Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "library-of-congress": {
      "url": "https://gateway.pipeworx.io/library-of-congress/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 965+ 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 Library Of Congress data" })

The gateway picks the right tool and fills the arguments automatically.
