gemini-researcher MCP

A stateless MCP server that proxies research queries to Gemini CLI, allowing agents like Claude Code and Cursor to perform deep codebase analysis locally. It reduces the calling agent's context window and model usage by offloading heavy analysis to Gemini's free tier, returning structured JSON results while maintaining read-only safety.
