Crates MCP Server

Answer Rust dependency questions from crates.io and docs.rs instead of from memory.

Package Registries & Dependency Supply Chain
Summary
The crate question, answered from the registry.

Model knowledge of the Rust ecosystem goes stale between releases. This checks the registry instead: which versions exist now, what a crate pulls in, and what its current documentation says.

What it is

A lookup against crates.io and docs.rs. It finds crates by name, reports what a crate is and which versions exist, lists what it depends on, and pulls its documentation.

What you get
  • Crates found by name
  • The details of a crate
  • The list of published versions
  • A crate's dependencies
  • Documentation from docs.rs
Requirements

A Rust toolchain — the server is built with cargo build --release and run as the resulting binary. It queries crates.io and docs.rs over the network.

Setup effort

Build from source — clone the repository and build it, then point your client at the binary
