AI agents use generate_image_prompt to create or update resources in Paid MCP Server Template — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Paid MCP Server Template environment.

WHY IT NEEDS A POLICY

Why generate_image_prompt needs a policy

This tool generates new content (image generation prompts) rather than retrieving or executing arbitrary operations. While the prompts themselves are not persisted by this tool, they are created/generated and passed to external services for image synthesis. The 'Write' category applies because the tool produces new data artifacts.

From the tool's definition The tool 'generate_image_prompt' creates or modifies prompt data that is then used by external image generation systems. It produces new textual content (optimized prompts) intended for downstream consumption, which represents data creation.
