Connect Windsurf to Nominatim (OpenStreetMap search)
One line gives Windsurf your Nominatim (OpenStreetMap search) account as tools: 4 endpoints, geocode, more, called with your own connection. No key in the prompt, a receipt for every call, revoke Windsurf's access alone any time.
Three steps
- Create a free 0n3 account and connect Nominatim (OpenStreetMap search). Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Windsurf. The mcp_config.json block.
- Ask Windsurf: whoami. Then: "List customers in Nominatim (OpenStreetMap search)".
