OpenStreetMap MCP server
The OpenStreetMap account API — who you are, your GPS traces, map notes (report a wrong bridge height or a closed road), and raw map data for a small area. Hosted by 0n3: 13 endpoints your AI can call with your own OpenStreetMap account, from Claude, ChatGPT, Cursor, Claude Code, Codex or Gemini CLI. One sign-in, one key per AI, a receipt for every call.

- Create a free account at 0n3.app and connect OpenStreetMap: paste a key or sign in through a door. It lands in your vault, encrypted.
- Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
- Ask your AI: whoami. It answers with your connected services. Then ask it to search notes in OpenStreetMap.

Questions
What can an AI do with the OpenStreetMap MCP server?
13 things: notes, traces, map data, account and more. Every call runs with your own OpenStreetMap connection and lands on a receipt.
Do I need to run anything on my computer?
No. 0n3 is hosted. Connect OpenStreetMap once, install 0n3 into your AI with one line, done.
Where does my OpenStreetMap key go?
Into your 0n3 vault, encrypted, one record per connection. The AI never sees it.
