Rust Docs Mcp Server

The Rust Docs MCP Server fetches documentation for a specified Rust crate, generates semantic embeddings, and provides a `query_rust_docs` tool that allows LLM coding assistants to retrieve accurate, up-to-date API information before generating code. It solves the problem of AI assistants lacking current knowledge of rapidly evolving Rust crates by enabling semantic search over cached documentation and generating answers through GPT-4o-mini based on retrieved context. Multiple server instances can run concurrently to provide documentation access for different crates during a single coding session.
