- How long do Mureka requests take?
- Typically from about 60 s (Mureka 9.5) to about 2 min (Mureka 9), by the catalog's estimates for each model's fastest route. The API answers at once with a job id, so nothing waits on an open connection while it runs.

- Yes. Add the varg MCP server (https://mcp.varg.ai/mcp) to Claude, ChatGPT, Cursor or any other MCP client and sign in with varg, with no API key to paste. The agent runs a model with call_tool, passing tool "music" and the model id, for example "model": "mureka_9".
