Developed an AI-assisted PR Comment Reply Tool for the github/github-mcp-server repository, focusing on automating and accelerating code review conversations. The feature enables AI agents to reply to existing pull request comments, supporting threaded discussions that streamline review workflows. Implemented as a write operation within the pull_requests toolset, the solution required robust API integration and backend development using Go, with comprehensive error handling for missing inputs and API failures. Eight targeted test cases and snapshot updates ensured reliability, while README and type updates improved maintainability. This work contributed to more efficient, automated PR reviews by enabling AI-driven responses within GitHub discussions.
