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.

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. diff --git a/.github/copilot-instructions.md b/.github/copilot-instructions.md new file mode 100644 index 000000000..f1b4cf9cb --- /dev/null +++ b/.github/copilot-instructions.md @@ -0,0 +1,292 @@ +# 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.

Lastly you will need to [Create a GitHub Personal Access Token](https://github.com/settings/personal-access-tokens/new). The MCP server can use many of the GitHub APIs, so enable the permissions that you feel comfortable granting your AI tools (to learn more about access tokens, please check out the [documentation](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens)). +

+ +## Dynamic Tool Discovery + +**Note**: This feature is currently in beta and is not available in the Remote GitHub MCP Server. Please test it out and let us know if you encounter any issues. + +Instead of starting with all tools enabled, you can turn on dynamic toolset discovery. Dynamic toolsets allow the MCP host to list and enable toolsets in response to a user prompt. This should help to avoid situations where the model gets confused by the sheer number of tools available. + +### Using Dynamic Tool Discovery + +When using the binary, you can pass the `--dynamic-toolsets` flag. + +```bash +./github-mcp-server --dynamic-toolsets +``` + +When using Docker, you can pass the toolsets as environment variables: + +```bash +docker run -i --rm \ + -e GITHUB_PERSONAL_ACCESS_TOKEN= \ + -e GITHUB_DYNAMIC_TOOLSETS=1 \ + ghcr.io/github/github-mcp-server +``` + +## Read-Only Mode -### Repository Content +To run the server in read-only mode, you can use the `--read-only` flag.

These solutions are typically created, administered, and maintained by GitHub Organization administrators. Collaborate with a GitHub Organization administrator to configure either a **GitHub App** or an **OAuth App** to allow your client application to utilize GitHub OAuth support. Furthermore, be aware that it may be necessary for users of your client application to register your **GitHub App** or **OAuth App** within their own GitHub Organization in order to generate authorization tokens capable of accessing Organization's GitHub resources. + +> [!TIP] +> Before proceeding, check whether your organization already supports one of these solutions. Administrators of your GitHub Organization can help you determine what **GitHub Apps** or **OAuth Apps** are already registered. If there's an existing **GitHub App** or **OAuth App** that fits your use case, consider reusing it for Remote MCP Authorization. That said, be sure to take heed of the following warning. + +> [!WARNING] +> Both **GitHub Apps** and **OAuth Apps** require the client application to pass a "client secret" in order to initiate the OAuth flow. If your client application is designed to run in an uncontrolled environment (i.e. customer-provided hardware), end users will be able to discover your "client secret" and potentially exploit it for other purposes. In such cases, our recommendation is to register a new **GitHub App** (or **OAuth App**) exclusively dedicated to servicing OAuth requests from your client application. + +#### Create an OAuth-enabled App Using the GitHub UI + +Detailed instructions for creating a **GitHub App** can be found at ["Creating GitHub Apps"](https://docs.github.com/en/apps/creating-github-apps/about-creating-github-apps/about-creating-github-apps#building-a-github-app). (RECOMMENDED)
+Detailed instructions for creating an **OAuth App** can be found ["Creating an OAuth App"](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app). + +For guidance on which type of app to choose, see ["Differences Between GitHub Apps and OAuth Apps"](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/differences-between-github-apps-and-oauth-apps). + +#### Things to Consider: +- Tokens provided by **GitHub Apps** are generally more secure because they: + - include an expiration + - include support for fine-grained permissions +- **GitHub Apps** must be installed on a GitHub Organization before they can be used.
In general, installation must be approved by someone in the Organization with administrator permissions. For more details, see [this explanation](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/differences-between-github-apps-and-oauth-apps#who-can-install-github-apps-and-authorize-oauth-apps).
By contrast, **OAuth Apps** don't require installation and, typically, can be used immediately. +- Members of an Organization may use the GitHub UI to [request that a GitHub App be installed](https://docs.github.com/en/apps/using-github-apps/requesting-a-github-app-from-your-organization-owner) organization-wide. +- While not strictly necessary, if you expect that a wide range of users will use your MCP Server, consider publishing its corresponding **GitHub App** or **OAuth App** on the [GitHub App Marketplace](https://github.com/marketplace?type=apps) to ensure that it's discoverable by your audience. + + +#### Initiating the OAuth Flow from your Client Application + +For **GitHub Apps**, details on initiating the OAuth flow from a client application are described in detail [here](https://docs.github.com/en/apps/creating-github-apps/authenticating-with-a-github-app/generating-a-user-access-token-for-a-github-app#using-the-web-application-flow-to-generate-a-user-access-token). + +For **OAuth Apps**, details on initiating the OAuth flow from a client application are described in detail [here](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/authorizing-oauth-apps#web-application-flow). + +> [!IMPORTANT] +> For endpoint discovery, be sure to honor the [`WWW-Authenticate` information provided](https://modelcontextprotocol.io/specification/draft/basic/authorization#authorization-server-location) by the Remote GitHub MCP Server rather than relying on hard-coded endpoints like `https://github.com/login/oauth/authorize`. + + +### Handling Organization Access Restrictions +Organizations may block **GitHub Apps** and **OAuth Apps** until explicitly approved. Within your client application code, you can provide actionable next steps for a smooth user experience in the event that OAuth-related calls fail due to your **GitHub App** or **OAuth App** being unavailable (i.e. not registered within the user's organization). + +1. Detect the specific error. +2. Notify the user clearly. +3. Depending on their GitHub organization privileges: + - Org Members: Prompt them to request approval from a GitHub organization admin, within the organization where access has not been approved. + - Org Admins: Link them to the corresponding GitHub organization’s App approval settings at `https://github.com/organizations/[ORG_NAME]/settings/oauth_application_policy` + + +## Essential Security Considerations +- **Token Storage**: Use secure platform APIs (e.g. keytar for Node.js). +- **Input Validation**: Sanitize all tool arguments. +- **HTTPS Only**: Never send requests over plaintext HTTP. Always use HTTPS in production. +- **PKCE:** We strongly recommend implementing [PKCE](https://datatracker.ietf.org/doc/html/rfc7636) for all OAuth flows to prevent code interception, to prepare for upcoming PKCE support. + +## Additional Resources +- [MCP Official Spec](https://modelcontextprotocol.io/specification/draft) +- [MCP SDKs](https://modelcontextprotocol.io/sdk/java/mcp-overview) +- [GitHub Docs on Creating GitHub Apps](https://docs.github.com/en/apps/creating-github-apps) +- [GitHub Docs on Using GitHub Apps](https://docs.github.com/en/apps/using-github-apps/about-using-github-apps) +- [GitHub Docs on Creating OAuth Apps](https://docs.github.com/en/apps/oauth-apps) +- GitHub Docs on Installing OAuth Apps into a [Personal Account](https://docs.github.com/en/apps/oauth-apps/using-oauth-apps/installing-an-oauth-app-in-your-personal-account) and [Organization](https://docs.github.com/en/apps/oauth-apps/using-oauth-apps/installing-an-oauth-app-in-your-organization) +- [Managing OAuth Apps at the Organization Level](https://docs.github.com/en/organizations/managing-oauth-access-to-your-organizations-data) +- [Managing Programmatic Access at the GitHub Organization Level](https://docs.github.com/en/organizations/managing-programmatic-access-to-your-organization) +- [Building Copilot Extensions](https://docs.github.com/en/copilot/building-copilot-extensions) +- [Managing App/Extension Visibility](https://docs.github.com/en/copilot/building-copilot-extensions/managing-the-availability-of-your-copilot-extension) (including GitHub Marketplace information) +- [Example Implementation in VS Code Repository](https://github.com/microsoft/vscode/blob/main/src/vs/workbench/api/common/extHostMcp.ts#L313) diff --git a/docs/installation-guides/README.md b/docs/installation-guides/README.md new file mode 100644 index 000000000..097d97b02 --- /dev/null +++ b/docs/installation-guides/README.md @@ -0,0 +1,99 @@ +# GitHub MCP Server Installation Guides + +This directory contains detailed installation instructions for the GitHub MCP Server across different host applications and IDEs.

Local GitHub MCP Server +* **Runs:** Locally alongside your IDE or application +* **Authentication & Controls:** Requires Personal Access Tokens (PATs). Users must generate and configure a PAT to connect.

Remote GitHub MCP Server +* **Runs:** As a hosted service accessed over the internet +* **Authentication & Controls:** (determined by the chosen authentication method) + * **GitHub App Installation Tokens:** Uses a signed JWT to request installation access tokens (similar to the OAuth 2.0 client credentials flow) to operate as the application itself. Provides granular control via [installation](https://docs.github.com/apps/using-github-apps/installing-a-github-app-from-a-third-party#requirements-to-install-a-github-app), [permissions](https://docs.github.com/apps/creating-github-apps/registering-a-github-app/choosing-permissions-for-a-github-app) and [repository access controls](https://docs.github.com/apps/using-github-apps/reviewing-and-modifying-installed-github-apps#modifying-repository-access). + * **OAuth Authorization Code Flow:** Uses the standard OAuth 2.0 Authorization Code flow. Controlled via [OAuth App access policies](https://docs.github.com/organizations/managing-oauth-access-to-your-organizations-data/about-oauth-app-access-restrictions) for OAuth apps. For GitHub Apps that sign in ([are authorized by](https://docs.github.com/apps/using-github-apps/authorizing-github-apps)) a user, control access to your organization via [installation](https://docs.github.com/apps/using-github-apps/installing-a-github-app-from-a-third-party#requirements-to-install-a-github-app). + * **Personal Access Tokens (PATs):** Managed via [PAT policies](https://docs.github.com/organizations/managing-programmatic-access-to-your-organization/setting-a-personal-access-token-policy-for-your-organization#restricting-access-by-personal-access-tokens). + * **SSO enforcement:** Applies when using OAuth Apps, GitHub Apps, and PATs to access resources in organizations and enterprises with SSO enabled. Acts as an overlay control. Users must have a valid SSO session for your organization or enterprise when signing into the app or creating the token in order for the token to access your resources. Learn more in the [SSO documentation](https://docs.github.com/enterprise-cloud@latest/authentication/authenticating-with-single-sign-on/about-authentication-with-single-sign-on#about-oauth-apps-github-apps-and-sso). + +**Supported Platforms:** Currently available only on GitHub Enterprise Cloud (GHEC). Remote hosting for GHES is not supported at this time. + +> **Note:** This does not apply to the Local GitHub MCP Server, which uses PATs and does not rely on GitHub App installations. + +#### Enterprise Install Considerations + +- When using the Remote GitHub MCP Server, if authenticating with OAuth instead of PAT, each host application must have a registered GitHub App (or OAuth App) to authenticate on behalf of the user. +- Enterprises may choose to install these apps in multiple organizations (e.g., per team or department) to scope access narrowly, or at the enterprise level to centralize access control across all child organizations. +- Enterprise installation is only supported for GitHub Apps. OAuth Apps can only be installed on a per organization basis in multi-org enterprises. + +### Security Principles for Both Modes +* **Authentication:** Required for all operations, no anonymous access +* **Authorization:** Access enforced by GitHub's native permission model. Users and apps cannot use an MCP server to access more resources than they could otherwise access normally via the API. +* **Communication:** All data transmitted over HTTPS with optional SSE for real-time updates +* **Rate Limiting:** Subject to GitHub API rate limits based on authentication method +* **Token Storage:** Tokens should be stored securely using platform-appropriate credential storage +* **Audit Trail:** All underlying API calls are logged in GitHub's audit log when available + +For integration architecture and implementation details, see the [Host Integration Guide](https://github.com/github/github-mcp-server/blob/main/docs/host-integration.md). + +## Where It's Used + +The GitHub MCP server can be accessed in various environments (referred to as "host" applications): +* **First-party Hosts:** GitHub Copilot in VS Code, Visual Studio, JetBrains, Eclipse, and Xcode with integrated MCP support, as well as Copilot Coding Agent. +* **Third-party Hosts:** Editors outside the GitHub ecosystem, such as Claude, Cursor, Windsurf, and Cline, that support connecting to MCP servers, as well as AI chat applications like Claude Desktop and other AI assistants that connect to MCP servers to fetch GitHub context or execute write actions. + +## What It Can Access + +The MCP server accesses GitHub resources based on the permissions granted through the chosen authentication method (PAT, OAuth, or GitHub App). These may include: +* Repository contents (files, branches, commits) +* Issues and pull requests +* Organization and team metadata +* User profile information +* Actions workflow runs, logs, and statuses +* Security and vulnerability alerts (if explicitly granted) + +Access is always constrained by GitHub's public API permission model and the authenticated user's privileges. + +## Control Mechanisms + +### 1. Copilot Editors (first-party) → MCP Servers in Copilot Policy + +* **Policy:** MCP servers in Copilot +* **Location:** Enterprise/Org → Policies → Copilot +* **What it controls:** When disabled, **completely blocks all GitHub MCP Server access** (both remote and local) for affected Copilot editors. Currently applies to VS Code and Copilot Coding Agent, with more Copilot editors expected to migrate to this policy over time. +* **Impact when disabled:** Host applications governed by this policy cannot connect to the GitHub MCP Server through any authentication method (OAuth, PAT, or GitHub App). +* **What it does NOT affect:** + * MCP support in Copilot on IDEs that are still in public preview (Visual Studio, JetBrains, Xcode, Eclipse) + * Third-party IDE or host apps (like Claude, Cursor, Windsurf) not governed by GitHub's Copilot policies + * Community-authored MCP servers using GitHub's public APIs + +> **Important:** This policy provides comprehensive control over GitHub MCP Server access in Copilot editors. When disabled, users in affected applications will not be able to use the GitHub MCP Server regardless of deployment mode (remote or local) or authentication method. + +#### Temporary: Copilot Editor Preview Policy + +* **Policy:** Editor Preview Features +* **Status:** Being phased out as editors migrate to the "MCP servers in Copilot" policy above, and once the Remote GitHub MCP server goes GA +* **What it controls:** When disabled, prevents remaining Copilot editors from using the Remote GitHub MCP Server through OAuth connections in all first-party and third-party host applications (does not affect local deployments or PAT authentication) + +> **Note:** As Copilot editors migrate from the "Copilot Editor Preview" policy to the "MCP servers in Copilot" policy, the scope of control becomes more centralized, blocking both remote and local GitHub MCP Server access when disabled. Access in third-party hosts is governed separately by OAuth App, GitHub App, and PAT policies. + +### 2. Third-Party Host Apps (e.g., Claude, Cursor, Windsurf) → OAuth App or GitHub App Controls + +#### a. OAuth App Access Policies +* **Control Mechanism:** OAuth App access restrictions +* **Location:** Org → Settings → Third-party Access → OAuth app policy +* **How it works:** + * Organization admins must approve OAuth App requests before host apps can access organization data + * Only applies when the host registers an OAuth App AND the user connects via OAuth 2.0 flow + +#### b. GitHub App Installation +* **Control Mechanism:** GitHub App installation and permissions +* **Location:** Org → Settings → Third-party Access → GitHub Apps +* **What it controls:** Organization admins must install the app, select repositories, and grant permissions before the app can access organization-owned data or resources through the Remote GitHub Server. +* **How it works:** + * Organization admins must install the app, specify repositories, and approve permissions + * Only applies when the host registers a GitHub App AND the user authenticates through that flow + +> **Note:** The authentication methods available depend on what your host application supports. While PATs work with any remote MCP-compatible host, OAuth and GitHub App authentication are only available if the host has registered an app with GitHub. Check your host application's documentation or support for more info. + +### 3. PAT Access from Any Host → PAT Restrictions + +* **Types:** Fine-grained PATs (recommended) and Classic tokens (legacy) +* **Location:** + * User level: [Personal Settings → Developer Settings → Personal Access Tokens](https://docs.github.com/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#fine-grained-personal-access-tokens) + * Enterprise/Organization level: [Enterprise/Organization → Settings → Personal Access Tokens](https://docs.github.com/organizations/managing-programmatic-access-to-your-organization/setting-a-personal-access-token-policy-for-your-organization) (to control PAT creation/access policies) +* **What it controls:** Applies to all host apps and both local & remote GitHub MCP servers when users authenticate via PAT. +* **How it works:** Access limited to the repositories and scopes selected on the token. +* **Limitations:** PATs do not adhere to OAuth App policies and GitHub App installation controls. They are user-scoped and not recommended for production automation. +* **Organization controls:** + * Classic PATs: Can be completely disabled organization-wide + * Fine-grained PATs: Cannot be disabled but require explicit approval for organization access + +> **Recommendation:** We recommend using fine-grained PATs over classic tokens. Classic tokens have broader scopes and can be disabled in organization settings. + +### 4.

Each toolset is provided as a distinct URL so you can mix and match to create the perfect combination of tools for your use-case. Add `/readonly` to the end of any URL to restrict the tools in the toolset to only those that enable read access. We also provide the option to use [headers](#headers) instead. + + +| Name | Description | API URL | 1-Click Install (VS Code) | Read-only Link | 1-Click Read-only Install (VS Code) |

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.

Remote ServerLocal Server
+ +```json +{ + "type": "http", + "url": "https://api.githubcopilot.com/mcp/", + "headers": { + "X-MCP-Tools": "get_file_contents,get_me,pull_request_read" + } +} +``` + + + +```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": "${input:github_token}" + } +} +``` + +
+ +--- + +### Enabling Specific Toolsets + +**Best for:** Users who want to enable multiple related toolsets. + + + + + + + +
Remote ServerLocal Server
+ +```json +{ + "type": "http", + "url": "https://api.githubcopilot.com/mcp/", + "headers": { + "X-MCP-Toolsets": "issues,pull_requests" + } +} +``` + + + +```json +{ + "type": "stdio", + "command": "go", + "args": [ + "run", + "./cmd/github-mcp-server", + "stdio", + "--toolsets=issues,pull_requests" + ], + "env": { + "GITHUB_PERSONAL_ACCESS_TOKEN": "${input:github_token}" + } +} +``` + +
+ +--- + +### 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. + + + + + + + +

+ +**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:** + + + + + + +

+ +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:** + + + + + + +
