Connect Claude Code to OpenStreetMap
One line gives Claude Code your OpenStreetMap account as tools: 13 endpoints, notes, traces, map data, called with your own connection. No key in the prompt, a receipt for every call, revoke Claude Code's access alone any time.
Three steps
- Create a free 0n3 account and connect OpenStreetMap. Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Claude Code. Claude in your Terminal. Paste one line, and Claude can use every app you added.
- Ask Claude Code: whoami. Then: "Search notes in OpenStreetMap".
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>"
The line above carries a placeholder; 0n3.app/install mints a real key named for Claude Code and fills it in.
