Tools

6 tools for geocoding and spatial queries against OpenStreetMap data:

Tool	Description
openstreetmap_search_places	Convert a place name or address to geographic coordinates and structured place data
openstreetmap_reverse_geocode	Convert latitude/longitude coordinates to the nearest address or place name
openstreetmap_lookup_objects	Fetch address details for one or more known OSM objects by their IDs
openstreetmap_query_nearby	Find OSM features within a radius around a geographic point
openstreetmap_query_bbox	Find OSM features within a rectangular bounding box
openstreetmap_query_raw	Execute a raw Overpass QL query for advanced spatial operations

openstreetmap_search_places

Convert a place name or address to geographic coordinates via Nominatim/OpenStreetMap.

• Two input modes: free-form query string (e.g., "Space Needle Seattle") or structured address fields (street, city, state, country, postal code) — mutually exclusive
• Country filtering via ISO 3166-1 alpha-2 codes (countrycodes)
• Data layer filtering: address, poi, railway, natural, manmade
• Feature type restriction: country, state, city, settlement
• Optional extra OSM tags (phone, website, opening_hours, wikidata)
• Preferred language override via BCP 47 code
• Returns results ordered by Nominatim importance score (global prominence)
• Results include coordinates, structured address, bounding box, OSM type/ID for chaining into openstreetmap_lookup_objects
