WHAT IT DOES

What tool_live_generate does on Open Google Image Generator MCP

AI agents invoke tool_live_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_live_generate needs a policy

This tool triggers an external API call to Google Cloud Vertex AI Gemini models to generate text via streaming. It executes an external operation whose effects depend on the input arguments. While it does not modify local data, it invokes a live external service (incurring potential API costs and producing dynamic outputs), placing it in the Execute category.

From the tool's definition Generate text using Gemini streaming. The full streamed response is accumulated and returned.
