Nominatim (OpenStreetMap) + ChatGPT
Free, no-auth geocoding using OpenStreetMap's Nominatim service. Forward + reverse geocoding + place lookup + search. 4 tools.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
(none — public API)
Step 1 — Get credentials
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.
- …
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Nominatim (OpenStreetMap). - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ
Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
