Why meshy_process_multicolor needs a policy

Every invocation of this tool deducts 10 credits from the user's account balance, making it a financial commitment. While the primary action is processing/transforming a 3D model (Execute/Write), the mandatory credit cost elevates it to Financial as the most severe applicable category. Misuse by an AI agent could drain account credits rapidly.

From the tool's definition Cost: 10 credits — the tool consumes credits (a financial/quota resource) each time it is invoked.

POLICY

How to control meshy_process_multicolor

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

policy.json

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

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