USGS Water MCP — wraps USGS National Water Information System (NWIS) REST services (free, no auth)

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

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

{
  "mcpServers": {
    "usgswater": {
      "url": "https://gateway.pipeworx.io/usgswater/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 250+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Usgswater data" })

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