This connects Claude to GitHub through Membrane's API layer, so you can query repos, manage issues and pull requests, create releases, and handle all the standard project management workflows without dealing with auth yourself. The free tier works fine. It's built around Membrane's CLI, which means you search for actions by intent rather than reading docs, and it handles OAuth and token refresh automatically. The action list is comprehensive enough for most repo management tasks, and when it's not, you can proxy raw requests directly to GitHub's API with auth still handled for you. Saves you from writing another OAuth flow or storing tokens locally.
