Nominatim Mcp Server

Wraps OpenStreetMap's Nominatim geocoder and Overpass spatial query API into six MCP tools. You can forward geocode addresses, reverse geocode coordinates, look up OSM objects by ID, and run proximity or bounding box searches for features like amenities, POIs, or any OSM tag pair. The raw Overpass QL tool lets you write custom queries when the convenience methods don't fit. Built on the author's mcp-ts-core framework, so it supports both stdio and streamable HTTP transports out of the box. Includes proper rate limiting, structured error codes, and OSM attribution on every response. Useful when you need location intelligence without standing up a full GIS stack or hitting commercial geocoding quotas.
