streetmap-port

OpenStreetMap geography as a CLI and a stdio MCP server in one bin: geocode a name to coordinates, reverse geocode coordinates to an address, search places, look up an OSM object by type and id, find places of a category near a point, and compute great-circle distances locally.

Geocoding, reverse geocoding and lookup use the public Nominatim API (with the descriptive User-Agent its usage policy requires); nearby search uses the public Overpass API. All requests go through an injectable fetch function, coordinates are validated before any request is built, and API error payloads are surfaced as errors — never replaced with invented places. distance_between is a pure local haversine computation and makes no API call.

Install

npx -y @reneturcios/streetmap-port mcp

CLI

streetmap-port mcp
streetmap-port geocode <query...>
streetmap-port reverse <lat> <lon>
streetmap-port search <query...>

streetmap-port distance <lat1> <lon1> <lat2> <lon2>
streetmap-port --version

Exit codes: 0 success, 1 API/validation error, 2 usage error.
