MCP server that provides up-to-date documentation for a specific Rust crate to LLM coding assistants. Each instance fetches one crate's documentation, generates embeddings for semantic search, and exposes a query_rust_docs tool that answers questions using summaries of the retrieved docs; multiple instances can run at once for different crates, and an OpenAI API key is required for embeddings and summarization.
