nominatim

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.
