WHAT IT DOES

What gpt_image_gen does on GPT Tools MCP Server

AI agents invoke gpt_image_gen to trigger actions in GPT Tools 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 gpt_image_gen needs a policy

Based on the server description, this tool likely triggers external operations (browser automation via Playwright to interact with ChatGPT for image generation). This constitutes an Execute-category action as it runs browser actions and triggers external operations. Confidence is reduced because the tool description is empty, requiring inference from context.

From the tool's definition Tool name 'gpt_image_gen' and sibling tool 'gpt_image_gen_batch' suggest image generation via Playwright browser automation as described in the server description.
