 Log in with OAuth instead of a token. On github.com the official image already includes the app credentials, so you provide none yourself — the server opens a browser login on first use and keeps the token in memory only. In Docker, publish a fixed callback port to loopback. Run the following command in the terminal (not in Claude Code CLI):
 
 ```bash
-claude mcp add github -e GITHUB_OAUTH_CALLBACK_PORT=8085 -- docker run -i --rm -p 127.0.0.1:8085:8085 -e GITHUB_OAUTH_CALLBACK_PORT ghcr.io/github/github-mcp-server

 See **[Local Server OAuth Login](../oauth-login.md)** for the native-binary flow (no fixed port), headless/device-code fallback, GitHub Enterprise, and bringing your own OAuth or GitHub App.

 To authenticate with a Personal Access Token instead (it takes precedence over OAuth):
 1. Run the following command in the terminal (not in Claude Code CLI):
 ```bash
-claude mcp add github -e GITHUB_PERSONAL_ACCESS_TOKEN=YOUR_GITHUB_PAT -- docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN ghcr.io/github/github-mcp-server
+claude mcp add github --env GITHUB_PERSONAL_ACCESS_TOKEN=YOUR_GITHUB_PAT -- docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN ghcr.io/github/github-mcp-server
 ```
 
 With an environment variable:
 ```bash
-claude mcp add github -e GITHUB_PERSONAL_ACCESS_TOKEN=$(grep GITHUB_PAT .env | cut -d '=' -f2) -- docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN ghcr.io/github/github-mcp-server

 ```
 2. Restart Claude Code
 3. Run `claude mcp list` to see if the GitHub server is configured
