How to Connect
Remote Plugin
No local installation needed. Your AI client connects to the remote endpoint directly.
Add this to your MCP configuration to connect:
{
"mcpServers": {
"io-github-pipeworx-io-crates": {
"url": "https://gateway.pipeworx.io/crates/mcp"
}
}

Crates.io MCP — wraps the crates.io REST API v1 (free, no auth)
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
Tools
| Tool | Description |
|---|---|
search_crates | Search crates.io for Rust packages by keyword. Returns crate name, description, downloads, latest version, and repo URL. |
get_crate | Get full metadata for a specific crate (e.g., 'serde'). Returns description, downloads, latest version, repo, homepage, and categories. |
get_versions | List all published versions for a crate in reverse chronological order. Returns version number, download count, and publish date. |
get_crate_dependencies | List the dependencies of a specific crate version — what itself depends on. Returns each dependency with its version requirement, kind (normal/build/dev), optional flag, enabled features, and target. Version is optional (defaults to the latest stable). Use for "what does depend on", dependency audits, or sizing a crate's footprint. |
get_crate_reverse_deps | List crates that DEPEND ON a given crate (reverse dependencies), most-downloaded first — answers "what uses ", "how widely adopted is ", "who depends on ". Returns the total dependent count plus the top dependents with their version requirement, dependency kind, and download counts. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"crates": {
"url": "https://gateway.pipeworx.io/crates/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/crates/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Crates data" })
The gateway picks the right tool and fills the arguments automatically.
