generate_image · Mcp Litmedia MCP: Risk & Policy

WHAT IT DOES

What generate_image does on Mcp Litmedia

AI agents invoke generate_image to trigger actions in Mcp Litmedia. 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 generate_image needs a policy

This tool triggers an external AI image generation operation on litmedia.ai, producing externally hosted artifacts (public URLs). It is not a simple read/query, nor does it delete data or move money. It executes an external operation whose output depends on the prompt arguments, placing it firmly in Execute.

From the tool's definition Génère une ou plusieurs images depuis un prompt texte via litmedia.ai. Retourne les URLs publiques des images générées.
