Rustdocs MCP Server

Rust is the language of AI

An MCP (Model Context Protocol) server that provides comprehensive access to Rust crate documentation, source code analysis, dependency trees, and module structure visualization. Built for agents to gain quality insights into Rust projects and build with confidence.

Warning

This is an entirely vibe coded project and was created as an experiment to see if LLMs can build a fully functional tool without human oversight.

The Problem: Agents Building in the Dark

The rise of AI agents has revolutionized software development, with new tools and libraries emerging at an unprecedented pace. However, this rapid evolution creates a critical challenge: agents cannot reliably build with tools they weren't trained on.

When an agent tries to use a new Rust crate:

• 🚫 Training data is outdated — The model hasn't seen recent crates or API changes
• 🚫 Documentation scraping is inefficient — Web scraping GitHub or docs.rs is slow and unreliable
• 🚫 Examples aren't enough — Copy-pasting README examples provides surface-level understanding
• 🚫 Internal structure is opaque — Agents can't explore how modules, traits, and types interconnect

This leads to frustrated developers watching their agents fail repeatedly, guessing at APIs,
