Crates.io MCP — wraps the crates.io REST API v1 (free, no auth)

Part of Pipeworx — an MCP gateway connecting AI agents to 1854+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

ToolDescription
search_cratesSearch crates.io for Rust packages by keyword. Returns crate name, description, downloads, latest version, and repo URL.
get_crateGet full metadata for a specific crate (e.g., 'serde'). Returns description, downloads, latest version, repo, homepage, and categories.
get_versionsList all published versions for a crate in reverse chronological order. Returns version number, download count, and publish date.
get_crate_dependenciesList the dependencies of a specific crate version — what <crate> 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 <crate> depend on", dependency audits, or sizing a crate's footprint.
get_crate_reverse_depsList crates that DEPEND ON a given crate (reverse dependencies), most-downloaded first — answers "what uses <crate>", "how widely adopted is <crate>", "who depends on <crate>". 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 1854+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/search_crates \
  -H 'Content-Type: application/json' \
  -d '{"query":"web framework"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/search_crates. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "crates": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-crates"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-crates

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

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.

الأسئلة الشائعة

ما هو Crates؟

Crates.io MCP — wraps the crates.io REST API v1 (free, no auth)

كيف أثبّت Crates؟

يعمل كخادم بعيد. في Claude Code: claude mcp add --transport http crates 'https://gateway.pipeworx.io/crates/mcp'. وفي العملاء الآخرين، الصق إعداد JSON من هذه الصفحة في إعدادات MCP الخاصة بهم.

هل يحتاج Crates إلى مفتاح API؟

لا يذكر إدراجه في السجل أي مفتاح أو سر إلزامي. قد تتطلب بعض الميزات حسابًا لدى الخدمة التي يتصل بها.

هل Crates مفتوح المصدر؟

نعم. شيفرته متاحة على GitHub بترخيص MIT.

من يصون Crates؟

ينشره pipeworx-io. يدرجه AI.tn لكنه لا يصونه ولا يوصي به.
