# mcp-usgswater

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

Part of [Pipeworx](https://pipeworx.io) — an MCP gateway connecting AI agents to 673+ live data sources.

## Tools

| Tool | Description |
|------|-------------|

## Quick Start

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

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

Or connect to the full Pipeworx gateway for access to all 673+ data sources:

```json
{
  "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 Usgswater data" })
```

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