+name: go-sdk-tool-migrator
+description: Agent specializing in migrating MCP tools from mark3labs/mcp-go to modelcontextprotocol/go-sdk
+---
+
+# Go SDK Tool Migrator Agent
+
+You are a specialized agent designed to assist developers in migrating MCP tools from the mark3labs/mcp-go library to the modelcontextprotocol/go-sdk. Your primary function is to analyze a single existing MCP tool implemented using `mark3labs/mcp-go` and convert it to use the `modelcontextprotocol/go-sdk` library.
+
+## Migration Process
+
+You should focus on ONLY the toolset you are asked to migrate and its corresponding test file. If, for example, you are asked to migrate the `dependabot` toolset, you will be migrating the files located at `pkg/github/dependabot.go` and `pkg/github/dependabot_test.go`. If there are additional tests or helper functions that fail to work with the new SDK, you should inform me of these issues so that I can address them, or instruct you on how to proceed.
+
+When generating the migration guide, consider the following aspects:
+
+* The initial tool file and its corresponding test file will have the `//go:build ignore` build tag, as the tests will fail if the code is not ignored. The `ignore` build tag should be removed before work begins.
+* The import for `github.com/mark3labs/mcp-go/mcp` should be changed to `github.com/modelcontextprotocol/go-sdk/mcp`
+* The return type for the tool constructor function should be updated from `mcp.Tool, server.ToolHandlerFunc` to `(mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])`.
+* The tool handler function signature should be updated to use generics, changing from `func(ctx context.Context, mcp.CallToolRequest) (*mcp.CallToolResult, error)` to `func(context.Context, *mcp.CallToolRequest, map[string]any) (*mcp.CallToolResult, any, error)`.
+* The `RequiredParam`, `RequiredInt`, `RequiredBigInt`, `OptionalParamOK`, `OptionalParam`, `OptionalIntParam`, `OptionalIntParamWithDefault`, `OptionalBoolParamWithDefault`, `OptionalStringArrayParam`, `OptionalBigIntArrayParam` and `OptionalCursorPaginationParams` functions should be changed to use the tool arguments that are now passed as a map in the tool handler function, rather than extracting them from the `mcp.CallToolRequest`.
+* `mcp.NewToolResultText`, `mcp.NewToolResultError`, `mcp.NewToolResultErrorFromErr` and `mcp.NewToolResultResource` no longer available in `modelcontextprotocol/go-sdk`. There are a few helper functions available in `pkg/utils/result.go` that can be used to replace these, in the `utils` package.
+
+### Schema Changes
+
+The biggest change when migrating MCP tools from mark3labs/mcp-go to modelcontextprotocol/go-sdk is the way input and output schemas are defined and handled. In `mark3labs/mcp-go`, input and output schemas were often defined using a DSL provided by the library. In `modelcontextprotocol/go-sdk`, schemas are defined using `jsonschema.Schema` structures using `github.com/google/jsonschema-go`, which are more verbose.
+
+When migrating a tool, you will need to convert the existing schema definitions to JSON Schema format. This involves defining the properties, types, and any validation rules using the JSON Schema specification.
+
+#### Example Schema Guide
+
+If we take an example of a tool that has the following input schema in mark3labs/mcp-go:
+
+```go
+...
+return mcp.NewTool(
+		"list_dependabot_alerts",
+		mcp.WithDescription(t("TOOL_LIST_DEPENDABOT_ALERTS_DESCRIPTION", "List dependabot alerts in a GitHub repository.")),
+		mcp.WithToolAnnotation(mcp.ToolAnnotation{
+			Title:        t("TOOL_LIST_DEPENDABOT_ALERTS_USER_TITLE", "List dependabot alerts"),
+			ReadOnlyHint: ToBoolPtr(true),
+		}),
+		mcp.WithString("owner",
+			mcp.Required(),
+			mcp.Description("The owner of the repository."),
+		),
+		mcp.WithString("repo",
+			mcp.Required(),
+			mcp.Description("The name of the repository."),
+		),
+		mcp.WithString("state",
+			mcp.Description("Filter dependabot alerts by state. Defaults to open"),
+			mcp.DefaultString("open"),
+			mcp.Enum("open", "fixed", "dismissed", "auto_dismissed"),
+		),
+		mcp.WithString("severity",
+			mcp.Description("Filter dependabot alerts by severity"),
+			mcp.Enum("low", "medium", "high", "critical"),
+		),
+	),
+...
+```
+
+The corresponding input schema in modelcontextprotocol/go-sdk would look like this:
+
+```go
+...
+return mcp.Tool{
+  Name: "list_dependabot_alerts",
+  Description: t("TOOL_LIST_DEPENDABOT_ALERTS_DESCRIPTION", "List dependabot alerts in a GitHub repository."),
+  Annotations: &mcp.ToolAnnotations{
+    Title: t("TOOL_LIST_DEPENDABOT_ALERTS_USER_TITLE", "List dependabot alerts"),
+    ReadOnlyHint: true,
+  },
+  InputSchema: &jsonschema.Schema{
+    Type: "object",
+    Properties: map[string]*jsonschema.Schema{
+      "owner": {
+        Type: "string",
+        Description: "The owner of the repository.",
+      },
+      "repo": {
+        Type: "string",
+        Description: "The name of the repository.",
+      },
+      "state": {
+        Type: "string",
+        Description: "Filter dependabot alerts by state. Defaults to open",
+        Enum: []any{"open", "fixed", "dismissed", "auto_dismissed"},
+        Default: "open",
+      },
+      "severity": {
+        Type: "string",
+        Description: "Filter dependabot alerts by severity",
+        Enum: []any{"low", "medium", "high", "critical"},
+      },
+    },
+    Required: []string{"owner", "repo"},
+  },
+}
+```
+
+### Tests
+
+After migrating the tool code and test file, ensure that all tests pass successfully. If any tests fail, review the error messages and adjust the migrated code as necessary to resolve any issues. If you encounter any challenges or need further assistance during the migration process, please let me know.
+
+At the end of your changes, you will continue to have an issue with the `toolsnaps` tests, these validate that the schema has not changed unexpectedly. You can update the snapshots by setting `UPDATE_TOOLSNAPS=true` before running the tests, e.g.:
+
+```bash
+UPDATE_TOOLSNAPS=true go test ./...
+```
+
+You should however, only update the toolsnaps after confirming that the schema changes are intentional and correct. Some schema changes are unavoidable, such as argument ordering, however the schemas themselves should remain logically equivalent.

+# GitHub MCP Server - Copilot Instructions
+
+## Project Overview
+
+This is the **GitHub MCP Server**, a Model Context Protocol (MCP) server that connects AI tools to GitHub's platform. It enables AI agents to manage repositories, issues, pull requests, workflows, and more through natural language.
+
+**Key Details:**
+- **Language:** Go 1.24+ (~38k lines of code)
+- **Type:** MCP server application with CLI interface
+- **Primary Package:** github-mcp-server (stdio MCP server - **this is the main focus**)
+- **Secondary Package:** mcpcurl (testing utility - don't break it, but not the priority)
+- **Framework:** Uses modelcontextprotocol/go-sdk for MCP protocol, google/go-github for GitHub API
+- **Size:** ~60MB repository, 70 Go files
+- **Library Usage:** This repository is also used as a library by the remote server. Functions that could be called by other repositories should be exported (capitalized), even if not required internally. Preserve existing export patterns.
+
+**Code Quality Standards:**
+- **Popular Open Source Repository** - High bar for code quality and clarity
+- **Comprehension First** - Code must be clear to a wide audience
+- **Clean Commits** - Atomic, focused changes with clear messages
+- **Structure** - Always maintain or improve, never degrade
+- **Code over Comments** - Prefer self-documenting code; comment only when necessary
+
+## Critical Build & Validation Steps
+
+### Required Commands (Run Before Committing)
+
+**ALWAYS run these commands in this exact order before using report_progress or finishing work:**
+
+1. **Format Code:** `script/lint` (runs `gofmt -s -w .` then `golangci-lint`)
+2. **Run Tests:** `script/test` (runs `go test -race ./...`)
+3. **Update Documentation:** `script/generate-docs` (if you modified MCP tools/toolsets)
+
+**These commands are FAST:** Lint ~1s, Tests ~1s (cached), Build ~1s
+
+### When Modifying MCP Tools/Endpoints
+
+If you change any MCP tool definitions or schemas:
+1. Run tests with `UPDATE_TOOLSNAPS=true go test ./...` to update toolsnaps
+2. Commit the updated `.snap` files in `pkg/github/__toolsnaps__/`
+3. Run `script/generate-docs` to update README.md
+4. Toolsnaps document API surface and ensure changes are intentional
+
+### Common Build Commands
+
+```bash
+# Download dependencies (rarely needed - usually cached)
+go mod download
+
+# Build the server binary
+go build -v ./cmd/github-mcp-server
+
+# Run the server
+./github-mcp-server stdio
+
+# Run specific package tests
+go test ./pkg/github -v
+
+# Run specific test
+go test ./pkg/github -run TestGetMe
+```

+```
+
+### Key Configuration Files
+
+- **go.mod / go.sum:** Go module dependencies (Go 1.24.0+)
+- **.golangci.yml:** Linter configuration (v2 format, ~15 linters enabled)
+- **Dockerfile:** Multi-stage build (golang:1.25.3-alpine → distroless)
+- **server.json:** MCP server metadata for registry
+- **.goreleaser.yaml:** Release automation config
+- **.gitignore:** Excludes bin/, dist/, vendor/, *.DS_Store, github-mcp-server binary
+
+### Important Scripts (script/ directory)
+
+- **script/lint** - Runs `gofmt` + `golangci-lint`. **MUST RUN** before committing
+- **script/test** - Runs `go test -race ./...` (full test suite)
+- **script/generate-docs** - Updates README.md tool documentation. Run after tool changes
+- **script/licenses** - Updates third-party license files when dependencies change
+- **script/licenses-check** - Validates license compliance (runs in CI)
+- **script/get-me** - Quick test script for get_me tool
+- **script/get-discussions** - Quick test for discussions
+- **script/tag-release** - **NEVER USE THIS** - releases are managed separately
+
+## GitHub Workflows (CI/CD)
+
+All workflows run on push/PR unless noted. Located in `.github/workflows/`:
+
+1. **go.yml** - Build and test on ubuntu/windows/macos. Runs `script/test` and builds binary
+2. **lint.yml** - Runs golangci-lint-action v2.5 (GitHub Action) with actions/setup-go stable
+3. **docs-check.yml** - Verifies README.md is up-to-date by running generate-docs and checking git diff
+4. **code-scanning.yml** - CodeQL security analysis for Go and GitHub Actions
+5. **license-check.yml** - Runs `script/licenses-check` to validate compliance
+6. **docker-publish.yml** - Publishes container image to ghcr.io
+7. **goreleaser.yml** - Creates releases (main branch only)
+8. **registry-releaser.yml** - Updates MCP registry
+
+**All of these must pass for PR merge.** If docs-check fails, run `script/generate-docs` and commit changes.
+
+## Testing Guidelines
+
+### Unit Tests
+
+- Use `testify` for assertions (`require` for critical checks, `assert` for non-blocking)
+- Tests are in `*_test.go` files alongside implementation (internal tests, not `_test` package)
+- Mock GitHub API with `go-github-mock` (REST) or `githubv4mock` (GraphQL)
+- Test structure for tools:
+  1. Test tool snapshot
+  2. Verify critical schema properties (e.g., ReadOnly annotation)
+  3. Table-driven behavioral tests
+
+### Toolsnaps (Tool Schema Snapshots)
+
+- Every MCP tool has a JSON schema snapshot in `pkg/github/__toolsnaps__/*.snap`
+- Tests fail if current schema differs from snapshot (shows diff)
+- To update after intentional changes: `UPDATE_TOOLSNAPS=true go test ./...`
+- **MUST commit updated .snap files** - they document API changes
+- Missing snapshots cause CI failure
+
+### End-to-End Tests
+
+- Located in `e2e/` directory with `e2e_test.go`
+- **Require GitHub PAT token** - you usually cannot run these yourself
+- Run with: `GITHUB_MCP_SERVER_E2E_TOKEN=<token> go test -v --tags e2e ./e2e`
+- Tests interact with live GitHub API via Docker container
+- **Keep e2e tests updated when changing MCP tools**
+- **Use only the e2e test style** when modifying tests in this directory
+- For debugging: `GITHUB_MCP_SERVER_E2E_DEBUG=true` runs in-process (no Docker)
+
+## Code Style & Linting
+
+### Go Code Requirements
+
+- **gofmt with simplify flag (-s)** - Automatically run by `script/lint`
+- **golangci-lint** with these linters enabled:
+  - bodyclose, gocritic, gosec, makezero, misspell, nakedret, revive
+  - errcheck, staticcheck, govet, ineffassign, unused
+- Exclusions for: third_party/, builtin/, examples/, generated code
+
+### Go Naming Conventions
+
+- **Acronyms in identifiers:** Use `ID` not `Id`, `API` not `Api`, `URL` not `Url`, `HTTP` not `Http`
+- Examples: `userID`, `getAPI`, `parseURL`, `HTTPClient`
+- This applies to variable names, function names, struct fields, etc.
+
+### Code Patterns
+
+- **Keep changes minimal and focused** on the specific issue being addressed
+- **Prefer clarity over cleverness** - code must be understandable by a wide audience
+- **Atomic commits** - each commit should be a complete, logical change
+- **Maintain or improve structure** - never degrade code organization
+- Use table-driven tests for behavioral testing
+- Comment sparingly - code should be self-documenting
+- Follow standard Go conventions (Effective Go, Go proverbs)
+- **Test changes thoroughly** before committing
+- Export functions (capitalize) if they could be used by other repos as a library
+
+## Common Development Workflows
+
+### Adding a New MCP Tool
+
+1. Add tool implementation in `pkg/github/` (e.g., `foo_tools.go`)
+2. Register tool in appropriate toolset in `pkg/github/` or `pkg/toolsets/`
+3. Write unit tests following the tool test pattern
+4. Run `UPDATE_TOOLSNAPS=true go test ./...` to create snapshot
+5. Run `script/generate-docs` to update README
+6. Run `script/lint` and `script/test` before committing
+7. If e2e tests are relevant, update `e2e/e2e_test.go` using existing test style
+8. Commit code + snapshots + README changes together
+
+### Fixing a Bug
+
+1. Write a failing test that reproduces the bug
+2. Fix the bug with minimal changes
+3. Verify test passes and existing tests still pass
+4. Run `script/lint` and `script/test`
+5. If tool schema changed, update toolsnaps (see above)
+
+### Updating Dependencies
+
+1. Update `go.mod` (e.g., `go get -u ./...` or manually)
+2. Run `go mod tidy`
+3. Run `script/licenses` to update license files
+4. Run `script/test` to verify nothing broke
+5. Commit go.mod, go.sum, and third-party-licenses* files
+
+## Common Errors & Solutions
+
+### "Documentation is out of date" in CI
+
+**Fix:** Run `script/generate-docs` and commit README.md changes
+
+### Toolsnap mismatch failures
+
+**Fix:** Run `UPDATE_TOOLSNAPS=true go test ./...` and commit updated .snap files
+
+### Lint failures
+
+**Fix:** Run `script/lint` locally - it will auto-format and show issues. Fix manually reported issues.
+
+### License check failures
+
+**Fix:** Run `script/licenses` to regenerate license files after dependency changes
+
+### Test failures after changing a tool
+
+**Likely causes:**
+1. Forgot to update toolsnaps - run with `UPDATE_TOOLSNAPS=true`
+2. Changed behavior broke existing tests - verify intent and fix tests
+3. Schema change not reflected in test - update test expectations
+
+## Environment Variables
+
+- **GITHUB_PERSONAL_ACCESS_TOKEN** - Required for server operation and e2e tests
+- **GITHUB_HOST** - For GitHub Enterprise Server (prefix with `https://`)
+- **GITHUB_TOOLSETS** - Comma-separated toolset list (overrides --toolsets flag)
+- **GITHUB_READ_ONLY** - Set to "1" for read-only mode
+- **GITHUB_DYNAMIC_TOOLSETS** - Set to "1" for dynamic toolset discovery
+- **UPDATE_TOOLSNAPS** - Set to "true" when running tests to update snapshots
+- **GITHUB_MCP_SERVER_E2E_TOKEN** - Token for e2e tests
+- **GITHUB_MCP_SERVER_E2E_DEBUG** - Set to "true" for in-process e2e debugging

+.gitignore          - Git exclusions (includes bin/, dist/, vendor/, binaries)
+.golangci.yml       - Linter configuration
+.goreleaser.yaml    - Release automation
+CODE_OF_CONDUCT.md  - Community guidelines

+SECURITY.md         - Security policy
+SUPPORT.md          - Support resources
+gemini-extension.json - Gemini CLI configuration
+go.mod / go.sum     - Go dependencies
+server.json         - MCP server registry metadata
+```
+
+### Main Entry Point
+
+`cmd/github-mcp-server/main.go` - Uses cobra for CLI, viper for config, supports:
+- `stdio` command (default) - MCP stdio transport
+- `generate-docs` command - Documentation generation
+- Flags: --toolsets, --read-only, --dynamic-toolsets, --gh-host, --log-file
+
+## Important Reminders
+
+1. **PRIMARY FOCUS:** The local stdio MCP server (github-mcp-server) - this is what you should work on and test with
+2. **REMOTE SERVER:** Ignore remote server instructions when making code changes (unless specifically asked). This repo is used as a library by the remote server, so keep functions exported (capitalized) if they could be called by other repos, even if not needed internally.
+3. **ALWAYS** trust these instructions first - only search if information is incomplete or incorrect
+4. **NEVER** use `script/tag-release` or push tags
+5. **NEVER** skip `script/lint` before committing Go code changes
+6. **ALWAYS** update toolsnaps when changing MCP tool schemas
+7. **ALWAYS** run `script/generate-docs` after modifying tools
+8. For specific test files, use `go test ./path -run TestName` not full suite
+9. E2E tests require PAT token - you likely cannot run them
+10. Toolsnaps are API documentation - treat changes seriously
+11. Build/test/lint are very fast (~1s each) - run frequently
+12. CI failures for docs-check or license-check have simple fixes (run the script)
+13. mcpcurl is secondary - don't break it, but it's not the priority

+You can also configure specific tools using the `--tools` flag. Tools can be used independently or combined with toolsets and dynamic toolsets discovery for fine-grained control.

+   ```bash
+   github-mcp-server --tools get_file_contents --dynamic-toolsets
+   ```
+   This registers `get_file_contents` plus the dynamic toolset tools (`enable_toolset`, `list_available_toolsets`, `get_toolset_tools`).
+
+**Important Notes:**
+- Tools, toolsets, and dynamic toolsets can all be used together
+- Read-only mode takes priority: write tools are skipped if `--read-only` is set, even if explicitly requested via `--tools`
+- Tool names must match exactly (e.g., `get_file_contents`, not `getFileContents`). Invalid tool names will cause the server to fail at startup with an error message
+- When tools are renamed, old names are preserved as aliases for backward compatibility. See [Deprecated Tool Aliases](docs/deprecated-tool-aliases.md) for details.

+## Lockdown Mode
+
+Lockdown mode limits the content that the server will surface from public repositories. When enabled, the server checks whether the author of each item has push access to the repository. Private repositories are unaffected, and collaborators keep full access to their own content.
+
+```bash
+./github-mcp-server --lockdown-mode
+```
+
+When running with Docker, set the corresponding environment variable:
+
+```bash
+docker run -i --rm \
+  -e GITHUB_PERSONAL_ACCESS_TOKEN=<your-token> \
+  -e GITHUB_LOCKDOWN_MODE=1 \
+  ghcr.io/github/github-mcp-server
+```
+
+The behavior of lockdown mode depends on the tool invoked.
+
+Following tools will return an error when the author lacks the push access:
+
+- `issue_read:get`
+- `pull_request_read:get`
+
+Following tools will filter out content from users lacking the push access:
+
+- `issue_read:get_comments`

+# Installing GitHub MCP Server in Antigravity
+
+This guide covers setting up the GitHub MCP Server in Google's Antigravity IDE.
+
+## Prerequisites
+
+- Antigravity IDE installed (latest version)
+- GitHub Personal Access Token with appropriate scopes
+
+## Installation Methods
+
+### Option 1: Remote Server (Recommended)
+
+Uses GitHub's hosted server at `https://api.githubcopilot.com/mcp/`.
+
+> [!NOTE]
+> We recommend this manual configuration method because the "official" installation via the Antigravity MCP Store currently has known issues (often resulting in Docker errors). This direct remote connection is more reliable.
+
+#### Step 1: Access MCP Configuration
+
+1. Open Antigravity
+2. Click the "..." (Additional Options) menu in the Agent panel
+3. Select "MCP Servers"
+4. Click "Manage MCP Servers"
+5. Click "View raw config"
+
+This will open your `mcp_config.json` file at:
+- **Windows**: `C:\Users\<USERNAME>\.gemini\antigravity\mcp_config.json`
+- **macOS/Linux**: `~/.gemini/antigravity/mcp_config.json`
+
+#### Step 2: Add Configuration
+
+Add the following to your `mcp_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "serverUrl": "https://api.githubcopilot.com/mcp/",
+      "headers": {
+        "Authorization": "Bearer YOUR_GITHUB_PAT"
+      }
+    }
+  }
+}
+```
+
+**Important**: Note that Antigravity uses `serverUrl` instead of `url` for HTTP-based MCP servers.
+
+#### Step 3: Configure Your Token
+
+Replace `YOUR_GITHUB_PAT` with your actual GitHub Personal Access Token.
+
+Create a token here: https://github.com/settings/tokens
+
+Recommended scopes:
+- `repo` - Full control of private repositories
+- `read:org` - Read org and team membership
+- `read:user` - Read user profile data
+
+#### Step 4: Restart Antigravity
+
+Close and reopen Antigravity for the changes to take effect.
+
+#### Step 5: Verify Installation
+
+1. Open the MCP Servers panel (... menu → MCP Servers)
+2. You should see "github" with a list of available tools
+3. You can now use GitHub tools in your conversations
+
+> [!NOTE]
+> The status indicator in the MCP Servers panel might not immediately turn green in some versions, but the tools will still function if configured correctly.
+
+### Option 2: Local Docker Server
+
+If you prefer running the server locally with Docker:
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "command": "docker",
+      "args": [
+        "run",
+        "-i",
+        "--rm",
+        "-e",
+        "GITHUB_PERSONAL_ACCESS_TOKEN",
+        "ghcr.io/github/github-mcp-server"
+      ],
+      "env": {
+        "GITHUB_PERSONAL_ACCESS_TOKEN": "YOUR_GITHUB_PAT"
+      }
+    }
+  }
+}
+```
+
+**Requirements**:
+- Docker Desktop installed and running
+- Docker must be in your system PATH
+
+## Troubleshooting
+
+### "Error: serverUrl or command must be specified"
+
+Make sure you're using `serverUrl` (not `url`) for the remote server configuration. Antigravity requires `serverUrl` for HTTP-based MCP servers.
+
+### Server not appearing in MCP list
+
+- Verify JSON syntax in your config file
+- Check that your PAT hasn't expired
+- Restart Antigravity completely
+
+### Tools not working
+
+- Ensure your PAT has the correct scopes
+- Check the MCP Servers panel for error messages
+- Verify internet connection for remote server
+
+## Available Tools
+
+Once installed, you'll have access to tools like:
+- `create_repository` - Create new GitHub repositories
+- `push_files` - Push files to repositories
+- `search_repositories` - Search for repositories
+- `create_or_update_file` - Manage file content
+- `get_file_contents` - Read file content
+- And many more...
+
+For a complete list of available tools and features, see the [main README](../../README.md).
+
+## Differences from Other IDEs
+
+- **Configuration key**: Antigravity uses `serverUrl` instead of `url` for HTTP servers
+- **Config location**: `.gemini/antigravity/mcp_config.json` instead of `.cursor/mcp.json`
+- **Tool limits**: Antigravity recommends keeping total enabled tools under 50 for optimal performance
+
+## Next Steps
+
+- Explore the [Server Configuration Guide](../server-configuration.md) for advanced options
+- Check out [toolsets documentation](../../README.md#available-toolsets) to customize available tools
+- See the [Remote Server Documentation](../remote-server.md) for more details

+# Install GitHub MCP Server in OpenAI Codex
+
+## Prerequisites
+
+1. OpenAI Codex (MCP-enabled) installed / available
+2. A [GitHub Personal Access Token](https://github.com/settings/personal-access-tokens/new)
+
+> The remote GitHub MCP server is hosted by GitHub at `https://api.githubcopilot.com/mcp/` and supports Streamable HTTP.
+
+## Remote Configuration
+
+Edit `~/.codex/config.toml` (shared by CLI and IDE extension) and add:
+
+```toml
+[mcp_servers.github]
+url = "https://api.githubcopilot.com/mcp/"
+# Replace with your real PAT (least-privilege scopes). Do NOT commit this.
+bearer_token_env_var = "GITHUB_PAT_TOKEN"
+```
+
+You can also add it via the Codex CLI:
+
+```cli
+codex mcp add github --url https://api.githubcopilot.com/mcp/  
+```
+
+<details>
+<summary><b>Storing Your PAT Securely</b></summary>
+<br>
+
+For security, avoid hardcoding your token. One common approach:
+
+1. Store your token in `.env` file
+```
+GITHUB_PAT_TOKEN=ghp_your_token_here
+```
+
+2. Add to .gitignore
+```bash
+echo -e ".env" >> .gitignore
+```
+</details>
+
+## Local Docker Configuration
+
+Use this if you prefer a local, self-hosted instance instead of the remote HTTP server, please refer to the [OpenAI documentation for configuration](https://developers.openai.com/codex/mcp).
+
+## Verification
+
+After starting Codex (CLI or IDE):
+1. Run `/mcp` in the TUI or use the IDE MCP panel; confirm `github` shows tools.
+2. Ask: "List my GitHub repositories".
+3. If tools are missing:
+   - Check token validity & scopes.
+   - Confirm correct table name: `[mcp_servers.github]`.
+
+## Usage
+
+After setup, Codex can interact with GitHub directly. It will use the default tool set automatically but can be [configured](../../README.md#default-toolset). Try these example prompts:
+
+**Repository Operations:**
+- "List my GitHub repositories"
+- "Show me recent issues in [owner/repo]"
+- "Create a new issue in [owner/repo] titled 'Bug: fix login'"
+
+**Pull Requests:**
+- "List open pull requests in [owner/repo]"
+- "Show me the diff for PR #123"
+- "Add a comment to PR #123: 'LGTM, approved'"
+
+**Actions & Workflows:**
+- "Show me recent workflow runs in [owner/repo]"
+- "Trigger the 'deploy' workflow in [owner/repo]"
+
+**Gists:**
+- "Create a gist with this code snippet"
+- "List my gists"
+
+> **Tip**: Use `/mcp` in the Codex UI to see all available GitHub tools and their descriptions.
+
+## Choosing Scopes for Your PAT
+
+Minimal useful scopes (adjust as needed):
+- `repo` (general repository operations)
+- `workflow` (if you want Actions workflow access)
+- `read:org` (if accessing org-level resources)
+- `project` (for classic project boards)
+- `gist` (if using gist tools)
+
+Use the principle of least privilege: add scopes only when a tool request fails due to permission.
+
+## Troubleshooting
+
+| Issue | Possible Cause | Fix |
+|-------|----------------|-----|
+| Authentication failed | Missing/incorrect PAT scope | Regenerate PAT; ensure `repo` scope present |
+| 401 Unauthorized (remote) | Token expired/revoked | Create new PAT; update `bearer_token_env_var` |
+| Server not listed | Wrong table name or syntax error | Use `[mcp_servers.github]`; validate TOML |
+| Tools missing / zero tools | Insufficient PAT scopes | Add needed scopes (workflow, gist, etc.) |
+| Token in file risks leakage | Committed accidentally | Rotate token; add file to `.gitignore` |
+
+## Security Best Practices
+1. Never commit tokens into version control
+3. Rotate tokens periodically
+4. Restrict scopes up front; expand only when required
+5. Remove unused PATs from your GitHub account

+# Server Configuration Guide
+
+This guide helps you choose the right configuration for your use case and shows you how to apply it. For the complete reference of available toolsets and tools, see the [README](../README.md#tool-configuration).
+
+## Quick Reference
+We currently support the following ways in which the GitHub MCP Server can be configured: 
+
+| Configuration | Remote Server | Local Server |
+|---------------|---------------|--------------|
+| Toolsets | `X-MCP-Toolsets` header or `/x/{toolset}` URL | `--toolsets` flag or `GITHUB_TOOLSETS` env var |
+| Individual Tools | `X-MCP-Tools` header | `--tools` flag or `GITHUB_TOOLS` env var |
+| Read-Only Mode | `X-MCP-Readonly` header or `/readonly` URL | `--read-only` flag or `GITHUB_READ_ONLY` env var |
+| Dynamic Mode | Not available | `--dynamic-toolsets` flag or `GITHUB_DYNAMIC_TOOLSETS` env var |
+| Lockdown Mode | `X-MCP-Lockdown` header | `--lockdown-mode` flag or `GITHUB_LOCKDOWN_MODE` env var |
+
+> **Default behavior:** If you don't specify any configuration, the server uses the **default toolsets**: `context`, `issues`, `pull_requests`, `repos`, `users`.
+
+---
+
+## How Configuration Works
+
+All configuration options are **composable**: you can combine toolsets, individual tools, dynamic discovery, read-only mode and lockdown mode in any way that suits your workflow.
+
+Note: **read-only** mode acts as a strict security filter that takes precedence over any other configuration, by disabling write tools even when explicitly requested.
+
+---
+
+## Configuration Examples
+
+The examples below use VS Code configuration format to illustrate the concepts. If you're using a different MCP host (Cursor, Claude Desktop, JetBrains, etc.), your configuration might need to look slightly different. See [installation guides](./installation-guides) for host-specific setup.
+
+### Enabling Specific Tools
+
+**Best for:** users who know exactly what they need and want to optimize context usage by loading only the tools they will use. 
+
+**Example:**
+
+<table>
+<tr><th>Remote Server</th><th>Local Server</th></tr>
+<tr valign="top">
+<td>
+
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/",
+  "headers": {
+    "X-MCP-Tools": "get_file_contents,get_me,pull_request_read"
+  }
+}
+```
+
+</td>
+<td>
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--tools=get_file_contents,get_me,pull_request_read"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+---
+
+### Enabling Specific Toolsets
+
+**Best for:** Users who want to enable multiple related toolsets.
+
+<table>
+<tr><th>Remote Server</th><th>Local Server</th></tr>
+<tr valign="top">
+<td>
+
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/",
+  "headers": {
+    "X-MCP-Toolsets": "issues,pull_requests"
+  }
+}
+```
+
+</td>
+<td>
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--toolsets=issues,pull_requests"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+---
+
+### Enabling Toolsets + Tools
+
+**Best for:** Users who want broad functionality from some areas, plus specific tools from others.
+
+Enable entire toolsets, then add individual tools from toolsets you don't want fully enabled.
+
+<table>
+<tr><th>Remote Server</th><th>Local Server</th></tr>
+<tr valign="top">
+<td>
+
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/",
+  "headers": {
+    "X-MCP-Toolsets": "repos,issues",
+    "X-MCP-Tools": "get_gist,pull_request_read"
+  }
+}
+```
+
+</td>
+<td>
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--toolsets=repos,issues",
+    "--tools=get_gist,pull_request_read"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+**Result:** All repository and issue tools, plus just the gist tools you need.
+
+---
+
+### Read-Only Mode
+
+**Best for:** Security conscious users who want to ensure the server won't allow operations that modify issues, pull requests, repositories etc.
+
+When active, this mode will disable all tools that are not read-only even if they were requested.
+
+**Example:** 
+<table>
+<tr><th>Remote Server</th><th>Local Server</th></tr>
+<tr valign="top">
+<td>
+
+**Option A: Header**
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/",
+  "headers": {
+    "X-MCP-Toolsets": "issues,repos,pull_requests",
+    "X-MCP-Readonly": "true"
+  }
+}
+```
+
+**Option B: URL path**
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/x/all/readonly"
+}
+```
+
+</td>
+<td>
+
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--toolsets=issues,repos,pull_requests",
+    "--read-only"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+> Even if `issues` toolset contains `create_issue`, it will be excluded in read-only mode.
+
+---
+
+### Dynamic Discovery (Local Only)
+
+**Best for:** Letting the LLM discover and enable toolsets as needed.
+
+Starts with only discovery tools (`enable_toolset`, `list_available_toolsets`, `get_toolset_tools`), then expands on demand.
+
+<table>
+<tr><th>Local Server Only</th></tr>
+<tr valign="top">
+<td>
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--dynamic-toolsets"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+**With some tools pre-enabled:**
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--dynamic-toolsets",
+    "--tools=get_me,search_code"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+When both dynamic mode and specific tools are enabled in the server configuration, the server will start with the 3 dynamic tools + the specified tools.
+
+---
+
+### Lockdown Mode
+
+**Best for:** Public repositories where you want to limit content from users without push access.
+
+Lockdown mode ensures the server only surfaces content in public repositories from users with push access to that repository. Private repositories are unaffected, and collaborators retain full access to their own content.
+
+**Example:**
+<table>
+<tr><th>Remote Server</th><th>Local Server</th></tr>
+<tr valign="top">
+<td>
+
+```json
+{
+  "type": "http",
+  "url": "https://api.githubcopilot.com/mcp/",
+  "headers": {
+    "X-MCP-Lockdown": "true"
+  }
+}
+```
+
+</td>
+<td>
+
+```json
+{
+  "type": "stdio",
+  "command": "go",
+  "args": [
+    "run",
+    "./cmd/github-mcp-server",
+    "stdio",
+    "--lockdown-mode"
+  ],
+  "env": {
+    "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}"
+  }
+}
+```
+
+</td>
+</tr>
+</table>
+
+---
+
+## Troubleshooting
+
+| Problem | Cause | Solution |
+|---------|-------|----------|
+| Server fails to start | Invalid tool name in `--tools` or `X-MCP-Tools` | Check tool name spelling; use exact names from [Tools list](../README.md#tools) |
+| Write tools not working | Read-only mode enabled | Remove `--read-only` flag or `X-MCP-Readonly` header |
+| Tools missing | Toolset not enabled | Add the required toolset or specific tool |
+| Dynamic tools not available | Using remote server | Dynamic mode is available in the local MCP server only |

+# Tool Renaming Guide
+
+How to safely rename MCP tools without breaking existing user configurations.
+
+## Overview
+
+When tools are renamed, users who have the old tool name in their MCP configuration (for example, in `X-MCP-Tools` headers for the remote MCP server or `--tools` flags for the local MCP server) would normally get errors. 
+The deprecation alias system allows us to maintain backward compatibility by silently resolving old tool names to their new canonical names.
+
+This allows us to rename tools safely, without introducing breaking changes for users that have a hard reference to those tools in their server configuration.
+
+## Quick Steps
+
+1. **Rename the tool** in your code (as usual, this will imply a range of changes like updating the tool registration, the tests and the toolsnaps).
+2. **Add a deprecation alias** in [pkg/github/deprecated_tool_aliases.go](../pkg/github/deprecated_tool_aliases.go):
+   ```go
+   var DeprecatedToolAliases = map[string]string{
+       "old_tool_name": "new_tool_name",
+   }
+   ```
+3. **Update documentation** (README, etc.) to reference the new canonical name
+
+That's it. The server will silently resolve old names to new ones. This will work across both local and remote MCP servers.
+
+## Example
+
+If renaming `get_issue` to `issue_read`:
+
+```go
+var DeprecatedToolAliases = map[string]string{
+    "get_issue": "issue_read",
+}
+```
+
+A user with this configuration:
+```json
+{
+  "--tools": "get_issue,get_file_contents"
+}
+```
+
+Will get `issue_read` and `get_file_contents` tools registered, with no errors.
+
+## Current Deprecations

+<!-- START AUTOMATED ALIASES -->

+|----------|----------|
+| *(none currently)* | |

+# Toolsets and Icons
+
+This document explains how to work with toolsets and icons in the GitHub MCP Server.
+
+## Toolset Overview
+
+Toolsets are logical groupings of related tools. Each toolset has metadata defined in `pkg/github/tools.go`:
+
+```go
+ToolsetMetadataRepos = inventory.ToolsetMetadata{
+    ID:          "repos",
+    Description: "GitHub Repository related tools",
+    Default:     true,
+    Icon:        "repo",
+}
+```
+
+### Toolset Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `ID` | `ToolsetID` | Unique identifier used in URLs and CLI flags (e.g., `repos`, `issues`) |
+| `Description` | `string` | Human-readable description shown in documentation |
+| `Default` | `bool` | Whether this toolset is enabled by default |
+| `Icon` | `string` | Octicon name for visual representation in MCP clients |
+
+## Adding Icons to Toolsets
+
+Icons help users quickly identify toolsets in MCP-compatible clients. We use [Primer Octicons](https://primer.style/foundations/icons) for all icons.
+
+### Step 1: Choose an Octicon
+
+Browse the [Octicon gallery](https://primer.style/foundations/icons) and select an appropriate icon. Use the base name without size suffix (e.g., `repo` not `repo-16`).
+
+### Step 2: Add Icon to Required Icons List
+
+Icons are defined in `pkg/octicons/required_icons.txt`, which is the single source of truth for which icons should be embedded:
+
+```
+# Required icons for the GitHub MCP Server
+# Add new icons below (one per line)
+repo
+issue-opened
+git-pull-request
+your-new-icon  # Add your icon here
+```
+
+### Step 3: Fetch the Icon Files
+
+Run the fetch-icons script to download and convert the icon:
+
+```bash
+# Fetch a specific icon
+script/fetch-icons your-new-icon
+
+# Or fetch all required icons
+script/fetch-icons
+```
+
+This script:
+- Downloads the 24px SVG from [Primer Octicons](https://github.com/primer/octicons)
+- Converts to PNG with light theme (dark icons for light backgrounds)
+- Converts to PNG with dark theme (white icons for dark backgrounds)
+- Saves both variants to `pkg/octicons/icons/`
+
+**Requirements:** The script requires `rsvg-convert`:
+- Ubuntu/Debian: `sudo apt-get install librsvg2-bin`
+- macOS: `brew install librsvg`
+
+### Step 4: Update the Toolset Metadata
+
+Add or update the `Icon` field in the toolset definition:
+
+```go
+// In pkg/github/tools.go
+ToolsetMetadataRepos = inventory.ToolsetMetadata{
+    ID:          "repos",
+    Description: "GitHub Repository related tools",
+    Default:     true,
+    Icon:        "repo",  // Add this line
+}
+```
+
+### Step 5: Regenerate Documentation
+
+Run the documentation generator to update all markdown files:
+
+```bash
+go run ./cmd/github-mcp-server generate-docs
+```
+
+This updates icons in:
+- `README.md` - Toolsets table and tool section headers
+- `docs/remote-server.md` - Remote toolsets table
+
+## Remote-Only Toolsets
+
+Some toolsets are only available in the remote GitHub MCP Server (hosted at `api.githubcopilot.com`). These are defined in `pkg/github/tools.go` with their icons, but are not registered with the local server:
+
+```go
+// Remote-only toolsets
+ToolsetMetadataCopilot = inventory.ToolsetMetadata{
+    ID:          "copilot",
+    Description: "Copilot related tools",
+    Icon:        "copilot",
+}
+```
+
+The `RemoteOnlyToolsets()` function returns the list of these toolsets for documentation generation.
+
+To add a new remote-only toolset:
+
+1. Add the metadata definition in `pkg/github/tools.go`
+2. Add it to the slice returned by `RemoteOnlyToolsets()`
+3. Regenerate documentation
+
+## Tool Icon Inheritance
+
+Individual tools inherit icons from their parent toolset. When a tool is registered with a toolset, its icons are automatically set:
+
+```go
+// In pkg/inventory/server_tool.go
+toolCopy.Icons = tool.Toolset.Icons()
+```
+
+This means you only need to set the icon once on the toolset, and all tools in that toolset will display the same icon.
+
+## How Icons Work in MCP
+
+The MCP protocol supports tool icons via the `icons` field. We provide icons in two formats:
+
+1. **Data URIs** - Base64-encoded PNG images embedded in the tool definition
+2. **Light/Dark variants** - Both theme variants are provided for proper display
+
+The `octicons.Icons()` function generates the MCP-compatible icon objects:
+
+```go
+// Returns []mcp.Icon with both light and dark variants
+icons := octicons.Icons("repo")
+```
+
+## Existing Toolset Icons
+
+| Toolset | Octicon Name |
+|---------|--------------|
+| Context | `person` |
+| Repositories | `repo` |
+| Issues | `issue-opened` |
+| Pull Requests | `git-pull-request` |
+| Git | `git-branch` |
+| Users | `people` |
+| Organizations | `organization` |
+| Actions | `workflow` |
+| Code Security | `codescan` |
+| Secret Protection | `shield-lock` |
+| Dependabot | `dependabot` |
+| Discussions | `comment-discussion` |
+| Gists | `logo-gist` |
+| Security Advisories | `shield` |
+| Projects | `project` |
+| Labels | `tag` |
+| Stargazers | `star` |
+| Notifications | `bell` |
+| Dynamic | `tools` |
+| Copilot | `copilot` |
+| Support Search | `book` |
+
+## Troubleshooting

+1. Ensure PNG files exist in `pkg/octicons/icons/` with `-light.png` and `-dark.png` suffixes
+2. Run `go run ./cmd/github-mcp-server generate-docs` to regenerate
+3. Check that the `Icon` field is set on the toolset metadata
+
+### Icons not appearing in MCP clients
+
+1. Verify the client supports MCP tool icons
+2. Check that the octicons package is properly generating base64 data URIs
+3. Ensure the icon name matches a file in `pkg/octicons/icons/`
+
+## CI Validation
+
+The following tests run in CI to catch icon issues early:
+
+### `pkg/octicons.TestEmbeddedIconsExist`
+
+Verifies that all icons listed in `pkg/octicons/required_icons.txt` have corresponding PNG files embedded.
+
+### `pkg/github.TestAllToolsetIconsExist`
+
+Verifies that all toolset `Icon` fields reference icons that are properly embedded.
+
+### `pkg/github.TestToolsetMetadataHasIcons`
+
+Ensures all toolsets have an `Icon` field set.
+
+If any of these tests fail:
+1. Add the missing icon to `pkg/octicons/required_icons.txt`
+2. Run `script/fetch-icons` to download the icon
+3. Commit the new icon files

+Field usage:

+	- Use EXACT returned field names (case-insensitive match). Don't invent names or IDs.
+	- Iteration synonyms (sprint/cycle) only if that field exists; map to the actual name (e.g. sprint:@current).
+	- Only include filters for fields that exist and are relevant.
+
+Pagination (mandatory):
+	- Loop while pageInfo.hasNextPage=true using after=pageInfo.nextCursor.
+	- Keep query, fields, per_page IDENTICAL on every page.
+	- Use before=pageInfo.prevCursor only when explicitly navigating to a previous page.
+
+Counting rules:
+	- Count items array length after full pagination.
+	- Never count field objects, content, or nested arrays as separate items.
+
+Summary vs list:
+	- Summaries ONLY if user uses verbs: analyze | summarize | summary | report | overview | insights.
+	- Listing verbs (list/show/get/fetch/display/enumerate) → enumerate + total.
+
+Self-check before returning:

+Query string - For advanced filtering of project items using GitHub's project filtering syntax:
+
+MUST reflect user intent; strongly prefer explicit content type if narrowed:
+	- "open issues" → state:open is:issue
+	- "merged PRs" → state:merged is:pr
+	- "items updated this week" → updated:>@today-7d (omit type only if mixed desired)
+	- "list all P1 priority items" → priority:p1 (omit state if user wants all, omit type if user specifies "items")
+	- "list all open P2 issues" → is:issue state:open priority:p2 (include state if user wants open or closed, include type if user specifies "issues" or "PRs")
+	- "all open issues I'm working on" → is:issue state:open assignee:@me
+
+Query Construction Heuristics:
+	a. Extract type nouns: issues → is:issue | PRs, Pulls, or Pull Requests → is:pr | tasks/tickets → is:issue (ask if ambiguity)
+	b. Map temporal phrases: "this week" → updated:>@today-7d
+	c. Map negations: "excluding wontfix" → -label:wontfix
+	d. Map priority adjectives: "high/sev1/p1" → priority:high OR priority:p1 (choose based on field presence)
+	e. When filtering by label, always use wildcard matching to account for cross-repository differences or emojis: (e.g. "bug 🐛" → label:*bug*)
+	f. When filtering by milestone, always use wildcard matching to account for cross-repository differences: (e.g. "v1.0" → milestone:*v1.0*)
+
+Syntax Essentials (items):
+   AND: space-separated. (label:bug priority:high).
+   OR: comma inside one qualifier (label:bug,critical).
+   NOT: leading '-' (-label:wontfix).
+   Hyphenate multi-word field names. (team-name:"Backend Team", story-points:>5).

-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
