Summary
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.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"crates": {
"url": "https://gateway.pipeworx.io/crates/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Crates data" })
The gateway picks the right tool and fills the arguments automatically.
