The Docker publishing workflow preserves tag versions, including prereleases, and lets branch, pull-request and nightly builds use the linked source revision.

+Repository tools expose output schemas and typed `structuredContent` when the negotiated MCP protocol version is a supported version `2026-07-28` or newer. Older clients, clients with an unknown protocol version, and clients omitting the version receive the existing content without an output schema or structured output. Unknown versions are not treated as supported merely because they sort after `2026-07-28`. -Actions +For `get_file_contents`, directory results (including field projections) are structured arrays. File downloads and metadata-only responses use a `content` array of typed text, embedded-resource, or resource-link blocks, preserving status messages, text, base64 blobs, empty files, and download links. Text-only repository mutations such as starring and deletion also return a structured `message`; fork responses distinguish a repository reference from an in-progress message. Repository deletion still requires its existing confirmation flow before returning a completed result. -- **cancel_workflow_run** - Cancel workflow run - - `owner`: Repository owner (string, required) - - `repo`: Repository name (string, required) - - `run_id`: The unique identifier of the workflow run (number, required) +Structured repository results use compact DTOs rather than raw REST objects. Release lookups share the compact release shape with release listings; Git references retain the ref, object type, and SHA; annotated tags retain tag/message/tagger/target information; deletion commits retain SHA, message, authors, tree SHA, parent SHAs, and a human-facing `html_url` when available. Directory entries retain file metadata and useful HTML/download links, but omit API and hypermedia routing URLs even when those fields were requested in a projection. Legacy and unknown protocol versions retain the original text byte-for-byte; modern text-only JSON responses serialize the same compact DTO as `structuredContent`. Non-text resource blocks and tool errors retain their existing content behavior. Structured projections use the same sanitized and filtered source as the legacy formatter. -- **delete_workflow_run_logs** - Delete workflow logs - - `owner`: Repository owner (string, required) - - `repo`: Repository name (string, required) - - `run_id`: The unique identifier of the workflow run (number, required) +For `get_repository_tree`, `list_gists`, `get_gist`, `create_gist`, and `update_gist`, gist results retain file names, contents, sizes, language/type information, timestamps, visibility, and compact owner profiles, while omitting API/node and Git transport URLs. Tree entries omit their derivable API URLs. Create/update gist results contain the gist ID and HTML URL. Modern JSON text and structured content serialize the same compact result. Older or unknown protocol versions retain byte-for-byte legacy text without an output schema or structured content. -- **download_workflow_run_artifact** - Download workflow artifact - - `artifact_id`: The unique identifier of the artifact (number, required) - - `owner`: Repository owner (string, required) - - `repo`: Repository name (string, required) +The issue metadata (`list_issue_types`, `list_issue_fields`), comment (`add_issue_comment`, `update_issue_comment`), dependency (`issue_dependency_read`, `issue_dependency_write`), and duplicate-detection (`find_duplicate`) tools provide typed `outputSchema` and `structuredContent` for negotiated supported protocol versions `2026-07-28` or newer. Older or unknown protocol versions retain the same text responses without these fields. Tool errors do not return structured content. Dependency and duplicate-detection tools retain their existing feature gates. -- **get_job_logs** - Get job logs - - `failed_only`: When true, gets logs for all failed jobs in run_id (boolean, optional) - - `job_id`: The unique identifier of the workflow job (required for single job logs) (number, optional) - - `owner`: Repository owner (string, required) - - `repo`: Repository name (string, required) - - `return_content`: Returns actual log content instead of URLs (boolean, optional) - - `run_id`: Workflow run ID (required when using failed_only) (number, optional) - - `tail_lines`: Number of lines to return from the end of the log (number, optional) +For negotiated supported protocol versions `2026-07-28` or newer, the consolidated Actions tools (`actions_list`, `actions_get`, `actions_run_trigger`) return structured objects with a `method` discriminant and a method-specific typed field; JSON text contains the same compact projection. Workflow, job, and artifact projections omit API/hypermedia URLs while retaining browser links and useful identifiers, states, timestamps, and usage durations. Run usage lists billable runner environments in deterministic name order. Older and unknown-protocol text responses remain unchanged; `get_job_logs` retains its typed content, URL, or failed-job collection variants. -- **get_workflow_run** - Get workflow run - - `owner`: Repository owner (string, required) - - `repo`: Repository name (string, required) - - `run_id`: The unique identifier of the workflow run (number, required) + +

Normal Go short-circuiting avoids checks that cannot affect the result, +while one request-owned memo ensures each flag actually reached is resolved at +most once across tools, resources, prompts, and `deps.IsFeatureEnabled`. +Unavailable named tool calls skip rule evaluation but remain registered so the +handler can return the specific client-availability error. + +Feature predicates are pure and may depend only on their resolver.

For local development, it can also be enabled explicitly with the `csv_output` feature flag: + +```bash +github-mcp-server stdio --features csv_output +``` + +Because this changes list tool response shape, clients that require JSON list responses should avoid enabling this feature. + +--- + +## How feature flags are resolved + +> [!NOTE] +> This section is for contributors. End users only need the table at the top of this page. + +Insiders is a **meta feature flag** — the same shape as `default` or `all` for toolsets. It expands once at startup into a curated set of individual feature flags, and from that point on every code path keys off concrete flags, never `InsidersMode` directly. New experimental work should always get its own flag and then be added to the insiders expansion list, never folded into `insiders` as a catch-all. + +### Resolution order + +1. **User input.** Users may opt into specific features: + - Local server: `--features=,` CLI flag (or `GITHUB_FEATURES` env var). + - HTTP server: `X-MCP-Features: ,` request header or a + `?features=,` server URL. Header presence takes precedence, + and the two request channels are never combined. +2. **Allowlist filter.** User-supplied flags are filtered against [`AllowedFeatureFlags`](../pkg/github/feature_flags.go). Anything not on the allowlist is silently dropped — flags missing from the allowlist can only be turned on by remote-server feature management, not by end users. +3. **Insiders expansion.** If insiders mode is on (`--insiders`, `/insiders` route, or `X-MCP-Insiders: true`), every flag in [`InsidersFeatureFlags`](../pkg/github/feature_flags.go) is unioned in. The insiders expansion is **not** re-validated against the allowlist — insiders is a server-controlled switch that can reach internal-only flags. +4. **Server-side fallback (remote server only).** Any flag not yet decided falls back to the remote server's feature manager, which can roll a feature out independently of user input or insiders membership. + +For tool availability, functional rules declare the flags they may read and are +evaluated lazily after request narrowing. Short-circuiting skips unnecessary +checks, and request-owned state memoizes each flag that is reached. The same +state backs `deps.IsFeatureEnabled`. + +`AllowedFeatureFlags` and `InsidersFeatureFlags` are deliberately independent sets: + +- A flag in **`AllowedFeatureFlags` only** is a regular opt-in: users can turn it on, but insiders does not auto-enable it. Granular issues/PRs flags work this way. +- A flag in **`InsidersFeatureFlags` only** is reachable through insiders (and remote-server rollouts), but cannot be enabled by user input. Internal-only experiments work this way. +- A flag in **both** is opt-in for end users *and* automatically on under insiders. + +### Adding a new feature flag + +1. Add a constant in `pkg/github/feature_flags.go`. +2. Add it to `AllowedFeatureFlags` if end users should be able to opt in via + `--features`, `X-MCP-Features`, or the `features` URL query parameter. +3. Add it to `InsidersFeatureFlags` if insiders mode should turn it on automatically. +4. For tool availability, attach an `inventory.NewFeatureRule` that declares every flag used by its predicate. For behavior inside a handler, use `deps.IsFeatureEnabled(ctx, FeatureFlagX)`. +5. Gate on concrete flags, never on `cfg.InsidersMode`. There is a `TestGitHubPackageDoesNotReadInsidersMode` guard test that fails if `pkg/github` reads `InsidersMode` directly. +6. The MCP-diff CI workflow picks up new entries in `AllowedFeatureFlags` automatically — see `.github/workflows/mcp-diff.yml`. diff --git a/docs/installation-guides/README.md b/docs/installation-guides/README.md index 097d97b027..888caf64a4 100644 --- a/docs/installation-guides/README.md +++ b/docs/installation-guides/README.md @@ -3,28 +3,42 @@ This directory contains detailed installation instructions for the GitHub MCP Server across different host applications and IDEs.

GitHub requires a client secret at the +token endpoint (for both OAuth Apps and GitHub Apps), so the exchange sends it +together with the PKCE verifier. Because this is a public, distributed client, +that secret is baked into the binary and is **not truly confidential** — PKCE is +what secures the flow: it binds the authorization code to this one login attempt, +so a code intercepted on the loopback redirect can't be redeemed anywhere else. + +To present the authorization URL, the server uses the most secure channel your +MCP client offers, in order: + +1. **Open your browser automatically** (native runs). +2. **URL elicitation** — the client prompts you with the link out of band, so the + URL never enters the model's context. Requires a client that supports MCP + elicitation (e.g. VS Code 1.101+). +3. **A message in the first tool response** — a last resort for clients without + elicitation. This includes a [security advisory](#url-elicitation-and-the-security-advisory). + +If the authorization-code flow can't be used — for example, a container with no +published callback port — the server falls back to the +[device-code flow](#headless-and-device-code-fallback). + +GitHub App tokens that expire are refreshed transparently using the refresh +token, so long-running sessions keep working without re-authorizing. + +## Quick start + +**Native binary (recommended).** Best experience: a random loopback port is +used and your browser opens automatically. On github.com with an official build, +no flags are needed: + +```bash +github-mcp-server stdio +``` + +With your own application: + +```bash +github-mcp-server stdio --oauth-client-id +``` + +VS Code (`.vscode/mcp.json`), using your own app: + +```json +{ + "servers": { + "github": { + "command": "/path/to/github-mcp-server", + "args": ["stdio", "--oauth-client-id", ""] + } + } +} +``` + +For Docker, see [Running in Docker](#running-in-docker) — containers need a fixed +callback port. + +## Configuration reference + +OAuth login is configured with these stdio flags (each has an environment +variable equivalent). Flags apply only to the `stdio` command. + +| Flag | Environment variable | Description | +|------|----------------------|-------------| +| `--oauth-client-id` | `GITHUB_OAUTH_CLIENT_ID` | OAuth App or GitHub App client ID. Enables OAuth login when no token is set. Defaults to the baked-in app on github.com for official builds. | +| `--oauth-client-secret` | `GITHUB_OAUTH_CLIENT_SECRET` | Client secret, **if your app requires one**. For distributed clients this is a public, non-confidential credential. | +| `--oauth-scopes` | `GITHUB_OAUTH_SCOPES` | Comma-separated scopes to request. Also [filters tools](#scope-filtering) to those scopes. Defaults to the full supported set. | +| `--oauth-callback-port` | `GITHUB_OAUTH_CALLBACK_PORT` | Fixed local port for the callback server. Defaults to a random port; set a fixed port when mapping it through Docker. | + +A static token still takes precedence: if `GITHUB_PERSONAL_ACCESS_TOKEN` is set, +the server uses it and skips OAuth entirely. + +## Scope filtering + +The scopes you request determine which tools are exposed. Requesting the full +supported set (the default) hides no tools. Narrowing `--oauth-scopes` both +narrows the token's grant **and** filters out tools that would need a scope you +didn't request, so the tool list reflects what the token can actually do. + +For example, requesting only `repo,read:org` hides tools that require `gist`, +`workflow`, `notifications`, and so on. + +## Running in Docker + +A container can't reach a random loopback port on your host, so Docker OAuth +needs a **fixed** callback port that you publish into the container. Use port +**8085** to match the official app's registered callback URL. + +```bash +docker run -i --rm \ + -p 127.0.0.1:8085:8085 \ + -e GITHUB_OAUTH_CALLBACK_PORT=8085 \ + ghcr.io/github/github-mcp-server +``` + +VS Code (`.vscode/mcp.json`): + +```json +{ + "servers": { + "github": { + "command": "docker", + "args": [ + "run", "-i", "--rm", + "-p", "127.0.0.1:8085:8085", + "-e", "GITHUB_OAUTH_CALLBACK_PORT", + "ghcr.io/github/github-mcp-server" + ], + "env": { "GITHUB_OAUTH_CALLBACK_PORT": "8085" } + } + } +} +``` + +Because the container can't open your host browser, the authorization URL +arrives via [URL elicitation](#url-elicitation-and-the-security-advisory) or the +tool-response message. After you authorize, your browser hits +`localhost:8085`, which Docker forwards into the container's callback. + +If you bring your own app for Docker, register its callback URL as exactly +`http://localhost:8085/callback`. + +> **Two safety properties to be aware of with a fixed port:** +> +> - **Publish to loopback only** (`-p 127.0.0.1:8085:8085`, not `-p 8085:8085`). +> Inside a container the callback necessarily listens on all interfaces, so a +> plain publish would expose the authorization code to your network. The +> server logs a warning reminding you of this when it binds inside a container. +> - **A busy port is fatal, by design.** With a fixed port, if the server can't +> bind it (another process already holds it), it **stops with an error** rather +> than silently falling back to the device flow. A port you didn't get could +> belong to another user's process positioned to receive the redirect, so the +> server refuses to continue. Free the port or choose a different +> `--oauth-callback-port`. + +## Headless and device-code fallback + +When there's no usable browser or callback — a remote shell, CI, or a container +started without a published port — the server uses GitHub's **device-code +flow**. You'll get a short code and a verification URL to open on any device: + +``` +Visit https://github.com/login/device and enter the code WDJB-MJHT to authorize +the GitHub MCP Server. +``` + +The server polls GitHub until you finish authorizing, then continues. No +callback port is involved, so this works anywhere. + +## URL elicitation and the security advisory + +URL elicitation lets your MCP client present the authorization URL to you +directly, keeping it **out of the model's context** — the model never sees the +link or any code embedded in it. This is the most secure way to hand off the +authorization step. + +If your client doesn't support elicitation, the server falls back to placing the +URL in a tool response and appends a short advisory: + +> Note: your MCP client does not appear to support secure URL elicitation. For +> improved security, consider asking your agent, CLI, or IDE to add it (for +> example, by opening an issue). + +If you see this, your authorization still works — but consider asking your client +vendor to add elicitation support. + +## Bring your own app + +You need your own application when targeting a non-github.com host, or when you'd +rather not use the baked-in app. Either application type works: + +- **[Create an OAuth App](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/creating-an-oauth-app)** — + simplest to set up. Grants the scopes you request. +- **[Register a GitHub App](https://docs.github.com/en/apps/creating-github-apps/registering-a-github-app/registering-a-github-app)** — + finer-grained, per-resource permissions and short-lived tokens that refresh + automatically. Enable **Device Flow** in the app settings if you want the + [headless fallback](#headless-and-device-code-fallback). + +When registering, set the authorization callback URL: + +- **Native runs** use a random loopback port. For loopback redirects GitHub does + not require the callback port to match, so registering + `http://localhost/callback` is sufficient. +- **Docker / fixed port** must match exactly: register + `http://localhost:8085/callback` (or whichever port you publish). + +Then pass the client ID (and secret, only if your app requires one): + +```bash +github-mcp-server stdio \ + --oauth-client-id \ + --oauth-client-secret +``` + +## GitHub Enterprise Server and ghe.com + +The baked-in app is registered on github.com only, so it is **not** used when you +set a custom host. GitHub Enterprise Server and `ghe.com` (Enterprise Cloud with +data residency) users must **bring their own app** registered on that host and +pass `--oauth-client-id`. + +Set the host with `--gh-host` / `GITHUB_HOST`; the server derives the OAuth +authorization, token, and device endpoints from it, so login is directed at your +instance's authorization server rather than github.com: + +```bash +github-mcp-server stdio \ + --gh-host https://github.example.com \ + --oauth-client-id +``` + +- For GitHub Enterprise Server, prefix the host with `https://`. +- For `ghe.com`, use `https://YOURSUBDOMAIN.ghe.com`. + +Register the app's callback URL on the same host (e.g. +`http://localhost/callback` for native runs, or `http://localhost:8085/callback` +for Docker). + +## Building from source with baked-in credentials + +Official builds embed the default OAuth client via linker flags at build time, so +they are not present in the source tree. To produce your own build with embedded +credentials, set them with `-ldflags`: + +```bash +go build -ldflags "\ + -X github.com/github/github-mcp-server/v2/internal/buildinfo.OAuthClientID= \ + -X github.com/github/github-mcp-server/v2/internal/buildinfo.OAuthClientSecret=" \ + ./cmd/github-mcp-server +``` + +Without these, a source build simply has no baked-in app and expects +`--oauth-client-id` (or a PAT) at runtime. diff --git a/docs/remote-server.md b/docs/remote-server.md index 5ee6aea640..be91009148 100644 --- a/docs/remote-server.md +++ b/docs/remote-server.md @@ -17,53 +17,66 @@ The remote server has [additional tools](#toolsets-only-available-in-the-remote- Below is a table of available toolsets for the remote GitHub MCP Server.

It +therefore serves `/.well-known/oauth-protected-resource` but does not serve +`/.well-known/oauth-authorization-server` unless a separately deployed authorization +server is explicitly hosted on the same origin. + +Clients discover authorization-server metadata from the issuer listed in +`authorization_servers`. For the default `https://github.com/login/oauth` issuer, +RFC 8414 path insertion produces +`https://github.com/.well-known/oauth-authorization-server/login/oauth`. Browser-based +clients require that authorization server and its discovery endpoints to support +their browser origin through CORS. If the selected authorization server does not, +configure `--authorization-server` to advertise a browser-compatible OAuth proxy. + +### Behind a Trusted Proxy (advanced) + +By default, the server ignores the `X-Forwarded-Host` and `X-Forwarded-Proto` headers when constructing OAuth resource metadata URLs, so an untrusted client cannot influence the URL advertised to MCP clients. For most deployments, setting `--base-url` to the externally visible URL is the right approach. + +If the server sits behind an internal forwarder that you fully control (for example, an in-cluster gateway that needs to preserve the originating hostname per request), you can opt into honoring those headers: + +```bash +github-mcp-server http --trust-proxy-headers +``` + +Equivalent environment variable: `GITHUB_TRUST_PROXY_HEADERS=1`. Only enable this when the upstream proxy is trusted to set or strip these headers; otherwise prefer `--base-url`. When `--base-url` is set, it always takes precedence and `--trust-proxy-headers` has no effect. + +### With an OAuth Proxy (GHES / non-standard authorization server) + +When deploying against GitHub Enterprise Server, GHES does not natively support the OAuth extensions required by MCP (RFC 8414 metadata discovery, RFC 7591 Dynamic Client Registration, PKCE). In this case you can run a separate OAuth proxy that implements the MCP OAuth spec and forwards authentication to GHES. Use `--authorization-server` to advertise the proxy's URL in the protected resource metadata instead of the one derived from `--gh-host`: + +```bash +github-mcp-server http \ + --gh-host https://github.example.com \ + --base-url https://mcp.example.com \ + --authorization-server https://mcp.example.com/oauth-proxy +``` + +The `authorization_servers` field in the protected resource metadata will then point at your proxy: + +```json +{ + "resource": "https://mcp.example.com", + "authorization_servers": [ + "https://mcp.example.com/oauth-proxy" + ], + ... +} +``` + +Equivalent environment variable: `GITHUB_AUTHORIZATION_SERVER=https://mcp.example.com/oauth-proxy`. + +When neither the flag nor environment variable is set, the server preserves the existing behavior and derives the authorization server from `--gh-host`. The override only changes the URL advertised in OAuth protected resource metadata; it does not change token validation or the GitHub API host. + +## Client Configuration + +### Using OAuth Authentication + +If your IDE or client has GitHub credentials configured (i.e. VS Code), simply reference the HTTP server: + +```json +{ + "type": "http", + "url": "http://localhost:8082" +} +``` + +The server will use the client's existing GitHub authentication. + +### Using Bearer Tokens or Custom Headers + +To provide PAT credentials, or to customize server behavior preferences, you can include additional headers in the client configuration: + +```json +{ + "type": "http", + "url": "http://localhost:8082", + "headers": { + "Authorization": "Bearer ghp_yourtokenhere", + "X-MCP-Toolsets": "default", + "X-MCP-Readonly": "true" + } +} +``` + +See [Remote Server](./remote-server.md) documentation for more details on client configuration options. diff --git a/docs/testing.md b/docs/testing.md index 226660e9de..2186b564b7 100644 --- a/docs/testing.md +++ b/docs/testing.md @@ -7,7 +7,7 @@ This project uses a combination of unit tests and end-to-end (e2e) tests to ensu - Unit tests are located alongside implementation, with filenames ending in `_test.go`. - Currently the preference is to use internal tests i.e. test files do not have `_test` package suffix. - Tests use [testify](https://github.com/stretchr/testify) for assertions and require statements.
