WHAT IT DOES

What generate_pixel_art does on Image Generation MCP Server

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

WHY IT NEEDS A POLICY

Why generate_pixel_art needs a policy

This tool generates new image data and persists it to disk based on the server's documented behavior of saving assets. This is a Write operation (creates new data reversibly). Severity is medium because: (1) disk space consumption and storage modifications are side effects, (2) generated content could potentially consume resources or be used for spam/abuse, but (3) the operation is reversible (files can be deleted).

From the tool's definition Tool name 'generate_pixel_art' and sibling 'generate_image' both create visual assets; server description states 'automatic saving of generated visual assets to disk', indicating the tool writes new files to the system.
