Cursor Flux Cloud flux_control_app

How to: Cursor Flux Cloud flux_control_app

client:Cursor transport:streamable-http tool:flux_control_app

Add Flux Cloud to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "flux-cloud-mcp": {
      "url": "https://mcp.runonflux.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something flux_control_app does. Cursor lists the server's tools on connect and calls flux_control_app itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Flux Cloud's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Set these first

Flux Cloud will not start until these are set, so flux_control_app never becomes available.

  • FLUX_PAYMENT_PRIVATE_KEY

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
