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

org).

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):

  1. 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.
  2. User-Agent header REQUIRED — every request must identify you. The connector pins User-Agent: AnythingMCP (https://anythingmcp.com) automatically.
  3. No heavy bulk geocoding — if you need >100 requests/hour, switch to MapTiler / OpenCage / Mapbox / Google.

Step 2 — Install the adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Step 3 — Add the connector in Claude

Recommended path — works on claude.ai web without editing any config file.

  1. Open claude.ai/customize/connectors.
  2. Click "Add custom connector".
  3. Fill in:
    • Name: Nominatim (OpenStreetMap)
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
