Context Protocol (MCP) server, which provides access to GitHub tools like
repository management, issue tracking, and pull request operations.

> The GitHub MCP integration requires a Personal Access Token (PAT) and cannot use the built-in `GITHUB_TOKEN`.
### Authentication
You can authenticate the MCP server with **either**:
1. **Personal Access Token (PAT)** – user-scoped token
2. **GitHub App Installation Token** (`ghs_…`) – short-lived, app-scoped token

### Enabling MCP in the action
Set `enable-github-mcp: true` and provide a token via `github-mcp-token`.
