WHAT IT DOES

What piapi_derive_image does on MCP TS Toolkit

AI agents invoke piapi_derive_image to trigger actions in MCP TS Toolkit. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why piapi_derive_image needs a policy

This tool generates/derives a new image by executing an AI model (Qubico Flux) to produce a variation. It triggers an external AI generation operation, placing it in the Execute category. It does not read existing data, write/modify stored data reversibly, delete data, or involve financial transactions. Severity is medium as misuse could result in unintended content generation or API resource consumption.
