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.

Parameter	Type	Required	Description
`prompt`	string	Yes	Text description of the image to generate
`savePath`	string	—	Optional Nextcloud path to save the generated image (e.g. '/Photos/generated.png'). If omitted, only the task ID is returned.

Parameters from the server's own tool schema.

RISK

Why generate_image is rated High

This tool triggers an external AI computation (text-to-image generation via Stable Diffusion/LocalAI). It executes an external operation whose effects depend on the input prompt. It is not purely a read, and while it may write a result, the primary action is executing an AI inference task on an external system. Misuse could consume significant compute resources or generate inappropriate content.

From the tool's definition Generate an image from a text prompt using Nextcloud's text-to-image AI provider... triggers external operations (AI inference via LocalAI/Stable Diffusion)

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.

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AIquila — Nextcloud MCP Server, apply this rule, and every generate_image call is checked against it from then on.

FAQ

Questions about generate_image

What does the generate_image tool do? +

Generate an image from a text prompt using Nextcloud's text-to-image AI provider (e.g. Stable Diffusion via LocalAI). Returns the task ID; use get_task_result to check completion. It is categorised as a Execute tool in the AIquila — Nextcloud MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does generate_image accept? +

generate_image accepts 2 parameters: prompt, savePath. Required: prompt. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on generate_image? +

Register the AIquila — Nextcloud MCP Server MCP server in PolicyLayer and add a rule for generate_image: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AIquila — Nextcloud MCP Server. Nothing to install.

What risk level is generate_image? +

generate_image is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit generate_image? +

Yes. Add a rate_limit block to the generate_image rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block generate_image completely? +

Set action: deny in the PolicyLayer policy for generate_image. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides generate_image? +

generate_image is provided by the AIquila — Nextcloud MCP Server MCP server (elgorro/aiquila). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
