Music Prompter

Turn a musical brief into a coherent prompt, an approved SandBase generation, or a verified multi-clip deliverable. Keep prompt writing useful without an external service, and use SandBase for every generative music call.

Read the SandBase API map before selecting or running a model.

Choose the delivery mode

• Prompt only: return a polished prompt, optional lyrics, and arrangement plan. Do not call a paid model.
• Generate one track: select and inspect a current SandBase music model, show the execution price and arguments, obtain confirmation, then generate.
• Produce a long or multi-part piece: plan the full arrangement, generate an approved set of clips, assemble them locally, and verify the result.

If the six sandbase_* MCP tools are unavailable, continue only in Prompt only mode. Point the user to the current setup instructions in the SandBase CLI repository; do not request a provider-specific API key or silently switch services.
