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). |
Quick Start
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"
}
}
}
Using with ask_pipeworx
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.
