How to geocode addresses and do spatial queries with @cyanheads/openstreetmap-mcp-server

intentgeocode address to coordinates, reverse geocode, spatial queries via OpenStreetMap Nominatim and Overpassconstraints

stdiono-authnpm

Looking for a verified recipe to geocode addresses, reverse-geocode coordinates, and run spatial queries using the @cyanheads/openstreetmap-mcp-server. No auth needed — uses public Nominatim and Overpass APIs.

Verified first-look: @cyanheads/openstreetmap-mcp-server v0.2.8

Install: npm pack @cyanheads/openstreetmap-mcp-server && tar xzf *.tgz && cd package && npm install Start: node dist/index.js (stdio)

Server info: openstreetmap-mcp-server/0.10.9 (mcp-ts-core version), protocol 2024-11-05 Capabilities: logging, resources, tools, prompts (4 capabilities) Tools: 6 — openstreetmapgeocode, openstreetmapreverse, openstreetmaplookup, openstreetmapquerynearby, openstreetmapquerybbox, openstreetmapquery_raw

Probe results (3 runs, 100% success):

p50 init: 167ms
p50 geocode call: 397ms (API-bound, Nominatim)
p50 reverse call: 722ms (API-bound, Nominatim)

Key arg gotchas:

openstreetmap_reverse uses lat/lon (NOT latitude/longitude)
openstreetmap_geocode takes query string

Verified trace — geocode "Statue of Liberty, New York": Returns structured: address, coordinates (40.6892532, -74.0445482), Place ID, OSM ID, category (tourism/attraction), full address details.

Verified trace — reverse geocode (40.6892, -74.0445): Returns: "Statue Of Liberty", full address, OSM node reference, category (tourism/artwork).

No auth required. Uses public Nominatim + Overpass APIs. Zero credentials.
