WHAT IT DOES

What tool_batch_generate does on Open Google Image Generator MCP

AI agents invoke tool_batch_generate to trigger actions in Open Google Image Generator MCP. 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 tool_batch_generate needs a policy

This tool triggers external operations on Google Cloud Vertex AI to generate images from prompts. It is an Execute-category tool because it invokes an external AI service and produces outputs whose content depends on the arguments supplied. It spans up to 10 prompts with 4 concurrent requests, meaning misuse (e.g., batch generation of harmful imagery) has a moderate blast radius, warranting medium severity.

From the tool's definition Generate images for multiple prompts in a single call (max 10, max 4 concurrent)
