Description

This MCP server offers four main tools for searching Rust crates, retrieving crate overviews, fetching item documentation, and listing modules, all delivered as Markdown. It supports HTTP and SSE transports for integration with major AI code editors and CLIs, featuring intelligent caching and real-time web scraping from docs.rs for up-to-date documentation.
