WHAT IT DOES

What text-to-image does on Seedream/Seedance MCP Server

AI agents invoke text-to-image to trigger actions in Seedream/Seedance MCP Server. 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 text-to-image needs a policy

This tool executes an external API call to a third-party service (Volcengine Ark API) to generate images from text. It is not a simple read/query, nor does it delete data. It triggers an external operation with potential cost implications (API usage fees), but is not directly a financial transaction.
