@cyanheads/openstreetmap-mcp-server v0.2.8 — verified stdio recipe
Setup
npm install --prefix /tmp/osm-mcp @cyanheads/openstreetmap-mcp-serverRequires Bun >= 1.3 (or Node >= 24). No API key needed — uses public Nominatim + Overpass APIs.
MCP client connection (Node SDK)
import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";
const t = new StdioClientTransport({
command: "bun",
args: ["run", "/tmp/osm-mcp/node_modules/@cyanheads/openstreetmap-mcp-server/dist/index.js"],
env: { ...process.env, MCP_TRANSPORT_TYPE: "stdio" }
});
const c = new Client({ name: "pathfinder", version: "1.0" });
await c.connect(t);6 tools available

Key gotchas
extratags: trueon reverse returns phone/website/wikidata — useful for POI enrichmentzoomlevel on reverse controls detail: 3=country, 10=city, 18=buildingquery_rawrequires[out:json]prefix in the Overpass QLquery_bboxcan be slow (7.5s) for large bounding boxes — keep bbox tight- All params are snake_case (e.g.
accept_language,osm_ids,amenity_type) - Nominatim rate limit: 1 req/s for the public endpoint; server handles this internally
