MCP (Claude, Cursor, VS Code)

The package is an MCP server — it lets AI assistants generate media through your FATTLY account.

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

Connect your client to the hosted server. No npm, no key to paste — you approve access in the browser.

https://fattly.app/api/mcp

In Claude: Settings → Connectors → Add custom connector → paste the URL. Full setup guide: https://fattly.app/claude-mcp

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

1. On fattly.app open Dashboard → API keys and create a key.
2. Add this to your client's MCP config:

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

Installing with an AI agent (Cline, Claude Code, Cursor)? Point it at llms-install.md.

Tools

21 tools — the same set as the hosted server (the local server forwards every call to fattly.app with your key, so new tools appear without updating the package).
