This project is no longer actively developed. Development focus has moved to b00t, and specifically to PromptExecution/rust-docs-mcp-b00t — our fork of Govcraft/rust-docs-mcp-server, which we support upstream and send patches back to.
If you're looking for a Rust crate-docs MCP server, use one of those two instead of this repo. This repo is kept around (archived, read-only) for reference — the Docker/GHCR image approach documented below worked, but we consolidated on the Govcraft-lineage tool rather than maintaining two independent implementations.
Rust Cargo Docs RAG MCP
rust-cargo-docs-rag-mcp is an MCP (Model Context Protocol) server that provides tools for Rust crate documentation lookup. It allows LLMs to look up documentation for Rust crates they are unfamiliar with.
This README focuses on how to build, version, release, and install the project using two common paths:
- pkgx (build/install locally from source)
- Docker image (published to GitHub Container Registry — GHCR)
