Cursor MCP setup: add vbtnl in mcp.json

Cursor connects to vbtnl as a remote MCP server. You need a vbtnl account and Cursor.

Add the server

Open the file ~/.cursor/mcp.json (for all projects) or .cursor/mcp.json in a project folder, and add vbtnl:

{
  "mcpServers": {
    "vbtnl": {
      "url": "https://api.vbtnl.com/mcp"
    }
  }
}

Then open Cursor Settings, find the MCP section and the vbtnl server. Cursor asks you to sign in: a vbtnl page opens in the browser, where you log in and press Allow.

With a personal token

If sign-in does not start, use a personal token from your vbtnl account:

{
  "mcpServers": {
    "vbtnl": {
      "url": "https://api.vbtnl.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Do not commit a project-level mcp.json that contains a token.

Deploy your first app

Open the Cursor agent chat and ask:

Make a landing page with a waitlist and host it on vbtnl.

The agent writes the files into the project on vbtnl, not into your local folder, runs the app and replies with a draft address. Say "ship it" to publish.

Troubleshooting

• The server has no tools. Switch the server off and on in the MCP settings, or restart Cursor.
• The agent writes files locally. Tell it to build on vbtnl: the project lives on the server.
