what3words MCP — 3-word grid geocoding

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

Tool	Description
`words_to_coords`	Convert a 3-word address ("filled.count.soap") to a lat/lon centre + 3m×3m bounding box.
`list_languages`	Supported languages for 3-word output (code + name).

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

{
  "mcpServers": {
    "what3words": {
      "url": "https://gateway.pipeworx.io/what3words/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 673+ 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 What3words data" })

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