This leads to frustrated developers watching their agents fail repeatedly, guessing at APIs, and producing broken code.

The Solution: Deep Crate Intelligence

This MCP server gives agents the tools they need to truly understand Rust crates:

• 🔍 Explore internal structure — Navigate module hierarchies and type relationships
• 📖 Access complete documentation — Full rustdoc with signatures, fields, and methods
• 🔗 Trace dependencies — Understand what a crate depends on and why
• 💾 Work offline — Cache crates locally for instant, reliable access
• 🎯 Query precisely — Search by pattern, kind, or path to find exactly what's needed

With these capabilities, agents can build confidently with any Rust crate — even ones released yesterday.

Agent Capabilities
