The Rust Docs MCP Server is a specialized Model Context Protocol (MCP) server designed to enhance AI-powered coding assistants' accuracy when working with Rust crates. It addresses the common issue where AI assistants provide outdated or incorrect code suggestions due to their training data cutoff, especially in fast-evolving ecosystems like Rust. This server fetches the latest documentation for a specified Rust crate, generates semantic embeddings using OpenAI's embedding models, and offers a tool that AI assistants can query to get precise, up-to-date information about the crate's API and usage. The server operates by downloading the crate's documentation via cargo doc, parsing the HTML content, and creating embeddings that represent the documentation semantically. These embeddings enable efficient semantic search to find the most relevant sections of the documentation in response to user queries. The server then uses an OpenAI language model to summarize and generate concise answers based solely on the retrieved documentation context, ensuring the responses are accurate and current. Users can run multiple instances of the server concurrently for different crates, allowing AI assistants to access documentation for various libraries during a coding session. The server supports specifying crate features required for documentation generation, which is essential for crates with optional features or runtime dependencies. Caching mechanisms store the downloaded documentation and generated embeddings locally to speed up subsequent server startups and reduce API usage costs. The server communicates over standard input/output using the MCP, exposing a tool named `query_rust_docs` that accepts questions about the crate and returns answers derived from the documentation. This project requires an OpenAI API key for embedding generation and summarization and network access to download crate dependencies and interact with the OpenAI API. It is available as precompiled binaries for easy installation or can be built from source using the Rust toolchain. Overall, the Rust Docs MCP Server significantly improves the relevance and correctness of AI-generated Rust code by providing real-time access to the latest crate documentation through a seamless MCP integration.
