Why music_generation needs a policy

The tool explicitly warns it may incur costs by calling the MiniMax API, placing it in the Financial category as it commits financial obligations (API usage charges) each time it is invoked.

From the tool's definition "This tool calls MiniMax API and may incur costs. Use only when explicitly requested by the user."

POLICY

How to control music_generation

PolicyLayer is an MCP gateway — it sits between your AI agents and MiniMax MCP JS, and nothing reaches the server without passing your rules. This is the rule we recommend for music_generation:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "music_generation": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to music_generation is blocked until a human approves it. The rest of the server keeps working.
