- Researchers — explore OpenStreetMap object details, administrative boundaries and place hierarchies
- Data Analysts — batch geocode addresses and extract structured location data
Frequently asked questions about the Nominatim MCP Server
Do I need an API key?
No! Nominatim is completely free and requires no authentication. It's powered by the OpenStreetMap community. Just subscribe and start searching. Rate limit is 1 request per second.
How accurate is the geocoding?
Nominatim uses OpenStreetMap data, which is crowd-sourced and varies by region. Urban areas typically have very accurate results. Use addressdetails=1 to get structured address components and namedetails=1 for multi-language names.
Can I convert coordinates to an address?
Yes! Use reverse_geocode with latitude and longitude. Returns the nearest address with street name, house number, city, state, postal code and country. Supports different zoom levels for varying detail granularity.
What is an OSM ID and how do I use it?
OSM IDs are unique identifiers for OpenStreetMap objects: N for nodes (points), W for ways (lines/areas), R for relations (groups). Use lookup_osm with IDs like 'W123456' or 'N987654'. Use get_details for comprehensive info on a single object.
