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/go/.github/copilot-instructions.md b/go/.github/copilot-instructions.md new file mode 100644 index 0000000..f1b4cf9 --- /dev/null +++ b/go/.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.

However, the specific configuration process, syntax and stability of the integration will vary by host application. While many may follow a similar format to the examples above, this is not guaranteed. Please refer to your host application's documentation for the correct MCP configuration syntax and setup process. + +### Build from source + +If you don't have Docker, you can use `go build` to build the binary in the +`cmd/github-mcp-server` directory, and use the `github-mcp-server stdio` command with the `GITHUB_PERSONAL_ACCESS_TOKEN` environment variable set to your token. To specify the output location of the build, use the `-o` flag. You should configure your server to use the built executable as its `command`. For example: + +```JSON +{ + "mcp": { + "servers": { + "github": { + "command": "/path/to/github-mcp-server", + "args": ["stdio"], + "env": { + "GITHUB_PERSONAL_ACCESS_TOKEN": "" + } + } + } + } +} +``` + +### CLI utilities + +The `github-mcp-server` binary includes a few CLI subcommands that are helpful for debugging and exploring the server. + +- `github-mcp-server tool-search ""` searches tools by name, description, and input parameter names. Use `--max-results` to return more matches. +Example (color output requires a TTY; use `docker run -t` (or `-it`) when running in Docker): +```bash +docker run -it --rm ghcr.io/github/github-mcp-server tool-search "issue" --max-results 5 +github-mcp-server tool-search "issue" --max-results 5 +``` + +## Tool Configuration + +The GitHub MCP Server supports enabling or disabling specific groups of functionalities via the `--toolsets` flag. This allows you to control which GitHub API capabilities are available to your AI tools. Enabling only the toolsets that you need can help the LLM with tool choice and reduce the context size. + +_Toolsets are not limited to Tools. Relevant MCP Resources and Prompts are also included where applicable._ + +When no toolsets are specified, [default toolsets](#default-toolset) are used. + +> **Looking for examples?** See the [Server Configuration Guide](./docs/server-configuration.md) for common recipes like minimal setups, read-only mode, and combining tools with toolsets. + +#### Specifying Toolsets + +To specify toolsets you want available to the LLM, you can pass an allow-list in two ways: + +1. **Using Command Line Argument**: + + ```bash + github-mcp-server --toolsets repos,issues,pull_requests,actions,code_security + ``` + +2. **Using Environment Variable**: + + ```bash + GITHUB_TOOLSETS="repos,issues,pull_requests,actions,code_security" ./github-mcp-server + ``` + +The environment variable `GITHUB_TOOLSETS` takes precedence over the command line argument if both are provided. + +#### Specifying Individual Tools + +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. + +1. **Using Command Line Argument**: + + ```bash + github-mcp-server --tools get_file_contents,issue_read,create_pull_request + ``` + +2. **Using Environment Variable**: + + ```bash + GITHUB_TOOLS="get_file_contents,issue_read,create_pull_request" ./github-mcp-server + ``` + +3. **Combining with Toolsets** (additive): + + ```bash + github-mcp-server --toolsets repos,issues --tools get_gist + ``` + + This registers all tools from `repos` and `issues` toolsets, plus `get_gist`. + +4. **Combining with Dynamic Toolsets** (additive): + + ```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. + +### Using Toolsets With Docker + +When using Docker, you can pass the toolsets as environment variables: + +```bash +docker run -i --rm \ + -e GITHUB_PERSONAL_ACCESS_TOKEN= \ + -e GITHUB_TOOLSETS="repos,issues,pull_requests,actions,code_security" \ + ghcr.io/github/github-mcp-server +``` + +### Using Tools With Docker + +When using Docker, you can pass specific tools as environment variables.

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 + +To run the server in read-only mode, you can use the `--read-only` flag. This will only offer read-only tools, preventing any modifications to repositories, issues, pull requests, etc. + +```bash +./github-mcp-server --read-only +``` + +When using Docker, you can pass the read-only mode as an environment variable: + +```bash +docker run -i --rm \ + -e GITHUB_PERSONAL_ACCESS_TOKEN= \ + -e GITHUB_READ_ONLY=1 \ + ghcr.io/github/github-mcp-server +``` + +## 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= \ + -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` +- `issue_read:get_sub_issues` +- `pull_request_read:get_comments` +- `pull_request_read:get_review_comments` +- `pull_request_read:get_reviews` + +## i18n / Overriding Descriptions + +The descriptions of the tools can be overridden by creating a +`github-mcp-server-config.json` file in the same directory as the binary. + +The file should contain a JSON object with the tool names as keys and the new +descriptions as values. For example: + +```json +{ + "TOOL_ADD_ISSUE_COMMENT_DESCRIPTION": "an alternative description", + "TOOL_CREATE_BRANCH_DESCRIPTION": "Create a new branch in a GitHub repository" +} +``` + +You can create an export of the current translations by running the binary with +the `--export-translations` flag. + +This flag will preserve any translations/overrides you have made, while adding +any new translations that have been added to the binary since the last time you +exported. + +```sh +./github-mcp-server --export-translations +cat github-mcp-server-config.json +``` + +You can also use ENV vars to override the descriptions. The environment +variable names are the same as the keys in the JSON file, prefixed with +`GITHUB_MCP_` and all uppercase. + +For example, to override the `TOOL_ADD_ISSUE_COMMENT_DESCRIPTION` tool, you can +set the following environment variable: + +```sh +export GITHUB_MCP_TOOL_ADD_ISSUE_COMMENT_DESCRIPTION="an alternative description" +``` + +## Library Usage + +The exported Go API of this module should currently be considered unstable, and subject to breaking changes.

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/go/docs/installation-guides/README.md b/go/docs/installation-guides/README.md new file mode 100644 index 0000000..be967f8 --- /dev/null +++ b/go/docs/installation-guides/README.md @@ -0,0 +1,100 @@ +# GitHub MCP Server Installation Guides + +This directory contains detailed installation instructions for the GitHub MCP Server across different host applications and IDEs.

It supports two deployment modes, both built on the same underlying codebase. + +### 1. 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. 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). + * Can optionally use GitHub App installation tokens when embedded in a GitHub App-based tool (rare). + +**Supported SKUs:** Can be used with GitHub Enterprise Server (GHES) and GitHub Enterprise Cloud (GHEC). + +### 2. 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. SSO Enforcement (overlay control) + +* **Location:** Enterprise/Organization → SSO settings +* **What it controls:** OAuth tokens and PATs must map to a recent SSO login to access SSO-protected organization data. +* **How it works:** Applies to ALL host apps when using OAuth or PATs. + +> **Exception:** Does NOT apply to GitHub App installation tokens (these are installation-scoped, not user-scoped) + +## Current Limitations + +While the GitHub MCP Server provides dynamic tooling and capabilities, the following enterprise governance features are not yet available: + +### Single Enterprise/Organization-Level Toggle + +GitHub does not provide a single toggle that blocks all GitHub MCP server traffic for every user. Admins can achieve equivalent coverage by combining the controls shown here: +* **First-party Copilot Editors (GitHub Copilot in VS Code, Visual Studio, JetBrains, Eclipse):** + * Disable the "MCP servers in Copilot" policy for comprehensive control + * Or disable the Editor Preview Features policy (for editors still using the legacy policy) +* **Third-party Host Applications:** + * Configure OAuth app restrictions + * Manage GitHub App installations +* **PAT Access in All Host Applications:** + * Implement fine-grained PAT policies (applies to both remote and local deployments) + +### MCP-Specific Audit Logging + +At present, MCP traffic appears in standard GitHub audit logs as normal API calls. Purpose-built logging for MCP is on the roadmap, but the following views are not yet available: +* Real-time list of active MCP connections +* Dashboards showing granular MCP usage data, like tools or host apps +* Granular, action-by-action audit logs + +Until those arrive, teams can continue to monitor MCP activity through existing API log entries and OAuth/GitHub App events. + +## Security Best Practices + +### For Organizations + +**GitHub App Management** +* Review [GitHub App installations](https://docs.github.com/apps/using-github-apps/reviewing-and-modifying-installed-github-apps) regularly +* Audit permissions and repository access +* Monitor installation events in audit logs +* Document approved GitHub Apps and their business purposes + +**OAuth App Governance** +* Manage [OAuth App access policies](https://docs.github.com/organizations/managing-oauth-access-to-your-organizations-data/about-oauth-app-access-restrictions) +* Establish review processes for approved applications +* Monitor which third-party applications are requesting access +* Maintain an allowlist of approved OAuth applications + +**Token Management** +* Mandate fine-grained Personal Access Tokens over classic tokens +* Establish token expiration policies (90 days maximum recommended) +* Implement automated token rotation reminders +* Review and enforce [PAT restrictions](https://docs.github.com/organizations/managing-programmatic-access-to-your-organization/setting-a-personal-access-token-policy-for-your-organization) at the appropriate level + +### For Developers and Users + +**Authentication Security** +* Prioritize OAuth 2.0 flows over long-lived tokens +* Prefer fine-grained PATs to PATs (Classic) +* Store tokens securely using platform-appropriate credential management +* Store credentials in secret management systems, not source code + +**Scope Minimization** +* Request only the minimum required scopes for your use case +* Regularly review and revoke unused token permissions +* Use repository-specific access instead of organization-wide access +* Document why each permission is needed for your integration + +## Resources + +**MCP:** +* [Model Context Protocol Specification](https://modelcontextprotocol.io/specification/2025-03-26) +* [Model Context Protocol Authorization](https://modelcontextprotocol.io/specification/draft/basic/authorization) + +**GitHub Governance & Controls:** +* [Managing OAuth App Access](https://docs.github.com/organizations/managing-oauth-access-to-your-organizations-data/about-oauth-app-access-restrictions) +* [GitHub App Permissions](https://docs.github.com/apps/creating-github-apps/registering-a-github-app/choosing-permissions-for-a-github-app) +* [Updating permissions for a GitHub App](https://docs.github.com/apps/using-github-apps/approving-updated-permissions-for-a-github-app) +* [PAT Policies](https://docs.github.com/organizations/managing-programmatic-access-to-your-organization/setting-a-personal-access-token-policy-for-your-organization) +* [Fine-grained PATs](https://docs.github.com/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#fine-grained-personal-access-tokens) +* [Setting a PAT policy for your organization](https://docs.github.com/organizations/managing-oauth-access-to-your-organizations-data/about-oauth-app-access-restrictions) + +--- + +**Questions or Feedback?** + +Open an [issue in the github-mcp-server repository](https://github.com/github/github-mcp-server/issues) with the label "policies & governance" attached. + +This document reflects GitHub MCP Server policies as of July 2025.

This ensures you only see tools that your token has permission to use, reducing clutter and preventing errors from attempting operations your token can't perform. + +> **Note:** This feature applies to **classic PATs** (tokens starting with `ghp_`). Fine-grained PATs, GitHub App installation tokens, and server-to-server tokens don't support scope detection and show all tools. + +## How It Works + +When the server starts with a classic PAT, it makes a lightweight HTTP HEAD request to the GitHub API to discover your token's scopes from the `X-OAuth-Scopes` header.

With PATs, scopes are fixed at token creation, so the server proactively hides tools you can't use. + +## OAuth Scope Challenges (Remote Server) + +When using the [remote MCP server](./remote-server.md) with OAuth authentication, the server uses a different approach called **scope challenges**. Instead of hiding tools upfront, all tools are available, and the server requests additional scopes on-demand when you try to use a tool that requires them. + +**How it works:** +1. You attempt to use a tool (e.g., creating an issue) +2. If your current OAuth token lacks the required scope, the server returns an OAuth scope challenge +3. Your MCP client prompts you to authorize the additional scope +4. After authorization, the operation completes successfully + +This provides a smoother user experience for OAuth users since you only grant permissions as needed, rather than requesting all scopes upfront. + +## Checking Your Token's Scopes + +To see what scopes your token has, you can run: + +```bash +curl -sI -H "Authorization: Bearer $GITHUB_PERSONAL_ACCESS_TOKEN" \ + https://api.github.com/user | grep -i x-oauth-scopes +``` + +Example output: +``` +x-oauth-scopes: delete_repo, gist, read:org, repo +``` + +## Scope Hierarchy + +Some scopes implicitly include others: + +- `repo` → includes `public_repo`, `security_events` +- `admin:org` → includes `write:org` → includes `read:org` +- `project` → includes `read:project` + +This means if your token has `repo`, tools requiring `security_events` will also be available. + +Each tool in the [README](../README.md#tools) lists its required and accepted OAuth scopes. + +## Public Repository Access + +Read-only tools that only require `repo` or `public_repo` scopes are **always visible**, even if your token doesn't have these scopes. This is because these tools work on public repositories without authentication. + +For example, `get_file_contents` is always available—you can read files from any public repository regardless of your token's scopes. However, write operations like `create_or_update_file` will be hidden if your token lacks `repo` scope. + +> **Note:** The GitHub API doesn't return `public_repo` in the `X-OAuth-Scopes` header—it's implicit. The server handles this by not filtering read-only repository tools. + +## Graceful Degradation + +If the server cannot fetch your token's scopes (e.g., network issues, rate limiting), it logs a warning and continues **without filtering**. This ensures the server remains usable even when scope detection fails. + +``` +WARN: failed to fetch token scopes, continuing without scope filtering +``` + +## Classic vs Fine-Grained Personal Access Tokens + +**Classic PATs** (`ghp_` prefix) support OAuth scopes and return them in the `X-OAuth-Scopes` header. Scope filtering works fully with these tokens. + +**Fine-grained PATs** (`github_pat_` prefix) use a different permission model based on repository access and specific permissions rather than OAuth scopes. They don't return the `X-OAuth-Scopes` header, so scope filtering is skipped.
