GraphHopper MCP server

Maps on OpenStreetMap — road distance and drive time (car and truck profiles), distance matrices, geocoding, isochrones, map matching, route optimization (VRP) and clustering. Hosted by 0n3: 15 endpoints your AI can call with your own GraphHopper account, from Claude, ChatGPT, Cursor, Claude Code, Codex or Gemini CLI. One sign-in, one key per AI, a receipt for every call.

Install in three steps

  1. Create a free account at 0n3.app and connect GraphHopper: paste a key or sign in through a door. It lands in your vault, encrypted.
  2. Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
  3. Ask your AI: whoami. It answers with your connected services. Then ask it to route in GraphHopper.
Paste this in Terminal and press Enter
claude mcp add --transport http --scope user 0n3 https://0n3.app/mcp --header "Authorization: Bearer <your 0n token>"

Questions

What can an AI do with the GraphHopper MCP server?

15 things: route, matrix, geocode, isochrone and more. Every call runs with your own GraphHopper connection and lands on a receipt.

Do I need to run anything on my computer?

No. 0n3 is hosted. Connect GraphHopper once, install 0n3 into your AI with one line, done.

Where does my GraphHopper key go?

Into your 0n3 vault, encrypted, one record per connection. The AI never sees it.
