Connect Windsurf to .0n App Marketplace

One line gives Windsurf your .0n App Marketplace account as tools: 5 endpoints, list apps, install app, checkout app, called with your own connection. No key in the prompt, a receipt for every call, revoke Windsurf's access alone any time.

Get the line for WindsurfConnect .0n App Marketplace first

Three steps

  1. Create a free 0n3 account and connect .0n App Marketplace. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Windsurf. The mcp_config.json block.
  3. Ask Windsurf: whoami. Then: "List apps in .0n App Marketplace".
Write it yourself · ~/.codeium/windsurf/mcp_config.json
{
  "mcpServers": {
    "0n3": {
      "serverUrl": "https://0n3.app/mcp",
      "headers": {
        "Authorization": "Bearer <your 0n token>"
      }
    }
  }
}

The line above carries a placeholder; 0n3.app/install mints a real key named for Windsurf and fills it in.
