MCP (Claude, Cursor)

The same package is an MCP server — it lets AI assistants generate through FATTLY. There are two ways to connect.

Option A — Hosted (no install, sign in with OAuth)

The fastest way: connect Claude straight to the hosted FATTLY MCP. No npm, no key to paste — you approve access in your browser.

In Claude → Settings → Connectors → Add custom connector, use this URL:

https://fattly.app/api/mcp

Claude discovers the login automatically and opens a consent page on fattly.app; approve it and the tools are ready. Uses your fattly.app account and credits.

Option B — Local (npx, with your API key)

Add this to your client's MCP config:

{
  "mcpServers": {
    "fattly": {
      "command": "npx",
      "args": ["-y", "fattly", "mcp"],
      "env": {
        "FATTLY_API_KEY": "gpx_live_YOUR_KEY"
      }
    }
  }
}

Available tools: fattly_credits, fattly_list_models, fattly_generate_image, fattly_generate_video, fattly_generate_audio.

API address

By default the CLI/MCP connects to the address set at login (or the default). Override it at login (fattly login --url https://your-domain) or with the FATTLY_API_URL environment variable.
