Code Review Analyst
Connects Claude to Google Gemini for automated code review workflows. Exposes 13 tools including diff generation, PR impact assessment, breaking change detection, code smell analysis, and documentation generation. Also includes logic verification through Gemini's code execution sandbox and web search with Grounding for current information. All outputs are validated JSON via Zod schemas. Supports the full MCP task lifecycle with polling and cancellation for long-running operations. Requires a Gemini API key and ships with 7 resources and 5 prompts over stdio. Useful when you want Gemini's analysis capabilities integrated directly into your MCP-enabled editor or workflow rather than switching contexts to external review tools.
