Wraps the OpenStreetMap Nominatim geocoding API so you can search addresses, reverse geocode coordinates, and query map data without leaving your MCP client. No API keys required since it uses OpenStreetMap's free public service. Part of the Pipeworx gateway ecosystem, which means you can either connect to this Nominatim endpoint directly or get it bundled with 673+ other data sources through their unified gateway. The ask_pipeworx tool lets you query in plain English instead of calling specific endpoints. Useful when you need location lookups or address validation in your agent workflows without managing another API account.
Nominatim MCP — wraps OpenStreetMap Nominatim geocoding API (free, no auth)
Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"nominatim": {
"url": "https://gateway.pipeworx.io/nominatim/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 Nominatim data" })
The gateway picks the right tool and fills the arguments automatically.
