VS Code reads MCP servers from a JSON file, and unlike most clients it requires you to declare the transport.

Add the server

Open the configuration file

Scope	Where
This workspace	`.vscode/mcp.json`
Every workspace	Command Palette, then MCP: Open User Configuration

Add Voiceflow

{
  "servers": {
    "voiceflow": {
      "type": "http",
      "url": "https://mcp.voiceflow.com/mcp"
    }
  }
}

Two details differ from other clients and both matter. The wrapper key is servers, not mcpServers. And "type": "http" is required, because VS Code will otherwise treat the entry as a local process to launch.

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

See Authentication for what the grant covers.

Confirm it worked

Ask Copilot Chat in agent mode 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
VS Code tries to run a command	`"type": "http"` is missing
The server never appears	The entry went in under `mcpServers` rather than `servers`
It appears but has no tools	The OAuth flow did not finish. Reconnect and complete the browser step
The tools never get called	Copilot Chat is not in agent mode

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