Setting up Nominatim (OpenStreetMap)
From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.
This connector uses Nominatim — OpenStreetMap's free geocoding service (nominatim.org).
Setup: NO API KEY REQUIRED. Just install the connector. The base URL is https://nominatim.openstreetmap.org.
HOWEVER — usage policy you MUST respect (otherwise you'll get banned):
- Max 1 request per second per IP. The connector does NOT throttle for you — your agent must self-limit. For bulk usage, run a self-hosted Nominatim or use a paid Nominatim host.
- User-Agent header REQUIRED — every request must identify you. The connector pins
User-Agent: AnythingMCP (https://anythingmcp.com)automatically. - No heavy bulk geocoding — if you need >100 requests/hour, switch to MapTiler / OpenCage / Mapbox / Google.
- Cache results for at least 24h — avoid re-geocoding the same address.
Coordinate convention: latitude FIRST then longitude (unlike Mapbox). Format is lat,lon in some endpoints, lat=X&lon=Y query params in others.
Languages: pass accept-language query param (e.g. de, en, fr) to localize place names.
Result format: format=json (compact), format=jsonv2 (richer), format=geojson (GeoJSON Feature). Default xml — always pass format=json for our tools.
Address importance ranking: results include importance (0-1, Wikipedia-derived). High importance = well-known place; low = obscure.
Out of scope here: address_lookup batch (use repeated single calls), search by category beyond default, photon (separate but related service).
