WHAT IT DOES

What openai_image_generation does on API Tester MCP Server

AI agents invoke openai_image_generation to trigger actions in API Tester 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 openai_image_generation needs a policy

This tool triggers an external operation (calling OpenAI's DALL-E API) to generate images. It executes an external service call whose effects (image generation, API usage/cost) depend on the arguments provided. While it has a minor financial dimension (API token consumption), it does not directly move money or commit financial obligations in the traditional sense, so Execute is the most appropriate category.
