Run this in your terminal, then type /mcp in Claude Code to sign in:

claude mcp add --transport http moongen https://www.moongenai.co/mcp

Cursor and others

Apps that support MCP sign-in only need the URL. For apps that use a config file, create an API key in Account → AI assistants and use:

{
    "mcpServers": {
        "moongen": {
            "url": "https://www.moongenai.co/mcp",
            "headers": {
                "Authorization": "Bearer YOUR_API_KEY"
            }
        }
    }
}

  • “How many credits do I have, and what would a 10-second video cost?”
  • “Show me the last five things I made.”
  • “Which model is best for a vertical product video, and what does it cost?”
  • “Add a warm British voice-over to that video saying: “Fresh from the lagoon, every morning.””
  • “I'm low on credits. Give me a link to buy more.”

Good to know

Does it cost more than the studio?

No. Every image and video costs the same credits as in the studio, the price is shown before anything runs, and failed generations are refunded automatically.

What can the assistant see?

Only your credit balance, the models and your past generations. It never sees your password or card details, and Moon Gen never sees the rest of your chat.

How do I disconnect it?

Open Account → AI assistants in the studio and click Disconnect, or remove the connector in the app. Changing your password disconnects every app too.

Why is my video not ready yet?

Videos take one to three minutes. Ask your assistant to check on it, or find it in your studio library.

The connection fails. What should I check?

Make sure you pasted the URL exactly as shown above, then remove the connector and add it again. If it still fails, contact us.
