GitHub gotchas
- After a failed OAuth attempt, click "Clear stored OAuth state" in the Inspector before switching to a token, or the connection keeps failing.
- OAuth does not work in clients that rely on dynamic client registration. Use a fine-grained personal access token instead, or a client with a pre-registered GitHub OAuth app.
- issue_write is an MCP Apps interactive form. Calling it as a plain tool shows a form and creates nothing, so clients without MCP Apps support cannot create issues this way.
