+# GitHub App authentication
+
+The local stdio server can authenticate as a GitHub App installation without a
+browser, device flow, or elicitation. It signs a short-lived JWT with the app's
+private key, exchanges it for an installation access token, and refreshes the
+token before it expires.
+
+This authentication mode is not available for the `http` command. HTTP clients
+must continue to provide their own `Authorization` token.
+
+> [!WARNING]
+> The private key can mint tokens for every repository and permission granted to
+> the installation. Keep it out of source control, restrict access to the server
+> process, and install the app only on the repositories it needs.
+
+## Configuration
+
+Configure exactly one of a Personal Access Token, OAuth login, or GitHub App
+authentication.
+
+| Flag | Environment variable | Description |
+|------|----------------------|-------------|
+| `--app-id` | `GITHUB_APP_ID` | App ID or client ID used as the JWT issuer |
+| `--app-installation-id` | `GITHUB_APP_INSTALLATION_ID` | Installation whose access token is used |
+| `--app-private-key-path` | `GITHUB_APP_PRIVATE_KEY_PATH` | Path to the private key PEM |
+| _(none)_ | `GITHUB_APP_PRIVATE_KEY` | PEM contents, optionally with literal `\n` escapes |
+
+A mounted private-key file is preferred. There is no flag for inline PEM
+contents because command-line arguments may be visible to other processes.
+
+## Usage
+
+```bash
+github-mcp-server stdio \
+ --app-id 123456 \
+ --app-installation-id 7891011 \
+ --app-private-key-path /secrets/github-app.pem
+```
+
+The equivalent environment configuration is:
+
+```bash
+export GITHUB_APP_ID=123456
+export GITHUB_APP_INSTALLATION_ID=7891011
+export GITHUB_APP_PRIVATE_KEY_PATH=/secrets/github-app.pem
+github-mcp-server stdio
+```
+
+For Docker, mount the key read-only:
+
+```bash
+docker run -i --rm \
+ -v /secrets/github-app.pem:/secrets/github-app.pem:ro \
+ -e GITHUB_APP_ID=123456 \
+ -e GITHUB_APP_INSTALLATION_ID=7891011 \
+ -e GITHUB_APP_PRIVATE_KEY_PATH=/secrets/github-app.pem \
+ ghcr.io/github/github-mcp-server
+```
+
+For GitHub Enterprise Server or `ghe.com`, also set `--gh-host` or
+`GITHUB_HOST`. The server derives the installation-token endpoint from that
+host.
+
+## Troubleshooting
+
+- **Private key required**: set `GITHUB_APP_PRIVATE_KEY_PATH` or
+ `GITHUB_APP_PRIVATE_KEY`.
+- **Invalid private key**: provide the RSA PEM generated in the GitHub App
+ settings. PKCS#1 and PKCS#8 keys are supported.
+- **401 from the installation-token endpoint**: verify the app ID or client ID,
+ private key, target host, and system clock.
+- **404 from the installation-token endpoint**: verify the installation ID and
+ that the app is installed on the target host.
