WHAT IT DOES

What generate_image does on AIquila — Nextcloud MCP Server

AI agents invoke generate_image to trigger actions in AIquila — Nextcloud 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.

RISK

Why generate_image is rated High

This tool triggers an AI image generation process based on arbitrary text input, executing an external operation (image generation) on the Nextcloud instance. It is not a simple read/write operation — it invokes a generative AI pipeline with potentially unbounded resource consumption and content risks.

RECOMMENDED RULE

The rule that runs generate_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AIquila — Nextcloud MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_image, this is the rule to start with:

generate_image Rate-limited

generate_image stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
