What is the Nominatim MCP Server?
Connect to Nominatim and search the world's most comprehensive open-source geographic database through natural conversation — no API key needed.
What you can do
- Address Search — Find any place by name, address or type of place (restaurants, schools, hospitals)
- Reverse Geocoding — Convert GPS coordinates to human-readable addresses
- OSM Lookup — Look up detailed info for any OpenStreetMap object by its ID
- Structured Addresses — Get detailed address components (street, city, state, postal code, country)
- Multi-language Names — Retrieve place names in different languages
- Bounding Boxes — Get geographic boundaries for cities, countries and regions
How it works
- Subscribe to this server
- No API key needed — start searching immediately
- Explore geographic data from Claude, Cursor, or any MCP-compatible client
No API key required — completely free, powered by OpenStreetMap community data.
Who is this for?
- Developers — geocode addresses and convert coordinates without paid geocoding services
- Travelers — find addresses and discover what's at any GPS coordinate
- Researchers — explore OpenStreetMap object details, administrative boundaries and place hierarchies
- Data Analysts — batch geocode addresses and extract structured location data
Built-in capabilities (5)
Returns the object's full name, display name, place rank, importance score, bounding box, parent place hierarchy, linked Wikipedia/Wikidata articles and optional extratags. OSM type: N (node), W (way), R (relation). Get detailed info for an OSM object
Returns status message and response latency. Useful for verifying the service is operational before making other requests. Get Nominatim server status
IDs are formatted as "type{id}" where type is N (node), W (way) or R (relation). Multiple IDs are comma-separated. Returns the object's display name, coordinates, bounding box and properties. Look up OSM objects by ID
Returns the nearest address, city, state, country and other location details. Supports different zoom levels for varying detail granularity. Convert coordinates to an address
Returns results with coordinates, bounding box, display name, address components and OSM type/id. Supports structured searches with country codes and viewbox for region prioritization. Rate limited to 1 request/second. Search for places by name or address

Frequently asked questions
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.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Nominatim MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
