About OpenStreetMap
Nominatim geocoding (place or address to coordinates and back) and Overpass spatial queries: everything within a radius of a point, everything inside a bounding box, or raw Overpass QL for advanced questions. Useful for geography, urban planning, public-health mapping and any study that needs distances, amenities or built-environment context.
Questions you can ask OpenStreetMap
Type them into Kahubi’s chat once OpenStreetMap is connected.
“How many pharmacies are within 1 km of each of these five hospital addresses?”
What comes back: Geocoded coordinates and counts of mapped features from OpenStreetMap.
“Geocode this list of school addresses in Malmö.”
What comes back: Coordinates with the matched address for each, so mismatches are easy to spot.
OpenStreetMap MCP tools
The 6 tools the OpenStreetMap server offers to Kahubi. The assistant picks the right one for each question.
openstreetmap_search_placesGeocode a place name or address to coordinates and structured place data via Nominatim.
openstreetmap_reverse_geocodeConvert a latitude/longitude pair to the nearest address or named place via Nominatim.
openstreetmap_lookup_objectsFetch 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.
openstreetmap_query_nearbyFind OSM features within a radius of a point via the Overpass API, the tool for "what is near X?" questions.
openstreetmap_query_bboxFind OSM features inside an area via the Overpass API, for surveys of everything in a region (openstreetmap_query_nearby covers proximity to a point).
openstreetmap_query_rawRun an arbitrary Overpass QL query for anything the convenience tools cannot express: multi-type or union queries, relation membership, historical queries, regex tag matching.
Using OpenStreetMap in Kahubi
- Community server. An open-source server maintained by the MCP community. Kahubi tests it with live queries before listing it and health-checks it regularly.
- Beta. The server works, but answers can be slower and its tools may still change.
- Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
- Your files stay private. Only the search the assistant writes for your question is sent to OpenStreetMap.
