  3. 03Retrieve Cargo package metadata
  4. 04Access download and maintainer health data
  5. 05Override remote snapshot or use local data

MCP support

It runs as a stdio MCP server and makes package metadata, downloads, and maintainer health data available to MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

npm/PyPI/Cargo package metadata + downloads + maintainer health. stdio MCP server.

Part of weiseer — AI-agent-native cached oracles.

Install

npm install -g @weiseer/package-meta-mcp

Use with Claude Desktop / Cursor / Cline / Continue / Windsurf

{
  "mcpServers": {
    "package-meta": {
      "command": "npx",
      "args": ["-y", "@weiseer/package-meta-mcp"]
    }
  }
}

Why use this instead of your agent doing it itself

The DIY cost in token-spend, latency, and rate-limit risk is 100-1500x our cost. See the weiseer organization README for the economic argument.

Environment

  • PKG_META_URL — override remote snapshot URL
  • PKG_META_LOCAL_ONLY=1 — skip remote fetch

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
