CodeWiki MCP — AI-generated docs for GitHub repos

Connects Claude to codewiki.google, the AI-generated wiki service for open-source repos. Exposes three tools: search indexed repositories, fetch full markdown docs or structured page hierarchies, and ask natural language questions with conversation history. The implementation speaks Google's internal batchexecute RPC protocol directly, handling the XSSI-prefixed responses and retry logic for you. Repo resolution is flexible,paste a GitHub URL, use owner/repo format, or just describe what you're looking for and it extracts the right repo via NLP. Ships with stdio transport by default, plus HTTP and SSE options. Useful when you need to pull comprehensive documentation into context without leaving your editor, or when you want to query unfamiliar codebases conversationally rather than grep through raw source.
