generateImage · Puch AI MCP Starter MCP: Risk & Policy

WHAT IT DOES

What generateImage does on Puch AI MCP Starter

AI agents invoke generateImage to trigger actions in Puch AI MCP Starter. 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 generateImage needs a policy

Generating an image involves triggering an external operation (likely an AI image generation service). The description is truncated and uninformative beyond confirming image generation. Since it triggers an external operation to create content, Execute is the most appropriate category. Confidence is lowered due to the incomplete description.

From the tool's definition Tool name 'generateImage' and truncated description 'Generate an image using the'
