Cursor keeps MCP servers in a JSON file, either for one project or for every project you open.

Add the server

Open the configuration file

Scope	File
Every project	`~/.cursor/mcp.json`
This project only	`.cursor/mcp.json`

Create the file if it does not exist.

Add Voiceflow

{
  "mcpServers": {
    "voiceflow": {
      "url": "https://mcp.voiceflow.com/mcp"
    }
  }
}

A remote server needs only url. Do not add a token: the server uses OAuth, and Cursor handles the exchange.

Cursor prompts you to authenticate the server and opens your browser. Approve the request, and the tab redirects back.

See Authentication for what the grant covers.

Confirm it worked

Ask Cursor to list your Voiceflow projects. A list means the transport, the grant, and your account access are all working.

If it does not connect

Symptom	Likely cause
The server never appears	The JSON is malformed, or it went in under `servers` rather than `mcpServers`
It appears but has no tools	The OAuth flow did not finish. Reconnect and complete the browser step
Tools exist but every call fails	The signed-in account cannot reach the workspace you are asking about

To disconnect, remove the voiceflow entry. That drops Cursor’s copy of the token; revoke access in Voiceflow to end every client’s session at once.
