Tools as reported by the server

openstreetmap_search_places
Geocode a place name or address to coordinates and structured place data via Nominatim. Send either a free-form query or the structured address fields (street, city, county, state, country, postalcode), never both; results are the best-ranked matches, not every matching object, and matching never us
openstreetmap_reverse_geocode
Convert a latitude/longitude pair to the nearest address or named place via Nominatim. The result is the closest indexed OSM object at the requested zoom (18 building, 10 city), which in dense areas can be a neighbouring feature rather than the one containing the coordinate; proximity and layer pick
openstreetmap_lookup_objects
Fetch the Nominatim address record for known OSM objects by ID, 50 per call with any more returned under deferred_ids, each prefixed N (node), W (way), or R (relation), e.g. "N240109189". Use it for IDs already in hand from openstreetmap_query_nearby or openstreetmap_query_bbox; it returns only obje
openstreetmap_query_nearby
Find OSM features within a radius of a point via the Overpass API, the tool for "what is near X?" questions. Filter with amenity, or with tag_key plus an optional tag_value, ANDing up to five more filters; every feature returns with its full OSM tag set (no extratags flag here), sorted nearest-first
openstreetmap_query_bbox
Find OSM features inside an area via the Overpass API, for surveys of everything in a region (openstreetmap_query_nearby covers proximity to a point). Scope with the four corner fields south, west, north, east, or with within and a single OSM boundary ref such as a city relation or a park way, which
openstreetmap_query_raw
Run an arbitrary Overpass QL query for anything the convenience tools cannot express: multi-type or union queries, relation membership, historical queries, regex tag matching. The query must include [out:json], e.g. "[out:json][timeout:15];node[\"natural\"=\"peak\"](47.5,-122.5,47.7,-122.2);out body
