Overview

AI-generated overview

Local stdio MCP server that gives an assistant OpenStreetMap geocoding, place search, nearby lookup and distance tools.

What you can do
  • Convert addresses or place names into coordinates, and coordinates back into the nearest address
  • Search places by name and fetch details of a single OSM node, way or relation
  • Find places of a given category near a coordinate pair
  • Compute great-circle distance in kilometres between two coordinate pairs, locally without any API call
When to use it
Useful when an assistant needs to resolve addresses to coordinates, look up OpenStreetMap places, explore what is near a location, or measure distances between points, without building its own geocoding integration.
Requirements
Runs as a local process via npx (Node.js) or Docker. No account, API key or environment variable is declared. Network access to the public Nominatim and Overpass APIs is needed for all tools except the local distance calculation.
Before you install
Queries are sent to the public OpenStreetMap Nominatim and Overpass services, so searched addresses and coordinates leave the machine. Those public APIs have usage policies and rate limits; heavy or automated use may be throttled or blocked. Results depend on OpenStreetMap data (ODbL) and may be incomplete or inaccurate.

Installation

In SourceWeft

  1. Open Streetmap Port in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

bash
npx -y @reneturcios/streetmap-port mcp

CLI

bash

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