A developer discovered a security vulnerability in their MCP server's GitHub integration, where the server's GitHub token possessed write permissions (`repo` scope) despite the server's code only intending to perform read operations. The developer had implemented a guard in the `_gh` function to prevent non-GET requests, but this guard was not included in the server's automated self-tests. This oversight meant that a future accidental or intentional change to use write capabilities could bypass the intended read-only restriction without immediate detection. AI
