Crates

Wraps the crates.io REST API v1 so you can search and query Rust package metadata directly from your MCP client. No authentication required. Runs through Pipeworx's gateway, which means you can either connect to this specific server or pull it in as part of their larger collection of 250+ data sources. Useful when you're working with Rust code and need to look up dependencies, check version compatibility, or explore what's available in the ecosystem without leaving your editor or chat interface. The ask_pipeworx feature lets you query in plain English instead of constructing tool calls manually.
