Summary
Wraps the what3words geocoding API into MCP so your assistant can translate those triplet addresses like "filled.count.soap" into actual coordinates and bounding boxes. You get two tools: words_to_coords for the conversion itself, and list_languages to see which locales are supported for output. Runs as a streamable HTTP server through Pipeworx's gateway, which means no local setup or API key wrangling in your config. Useful when you're building location features and want to handle what3words references without leaving the MCP ecosystem or when users drop three word addresses into chat and expect your agent to know where that is.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

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.
