This is not handled currently by [`server.go`](https://github.com/github/github-mcp-server/blob/56c1fce434d98cc5d4935979cc4c661a29bd0ed6/pkg/github/server.go#L234)\n\nExample Error:\n\n\u003e ```\n\u003e {\n\u003e   `body`: `This is a test issue created via Claude to verify GitHub API functionality.
