How to control image_multi_reference ↓

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

Medium Risk

Based on the server description mentioning 'multi-reference image fusion' and the tool name, this likely generates or creates a new image by fusing multiple reference images. This is a Write operation (creating new data). Confidence is lowered due to the empty description.

From the tool's definition Tool name 'image_multi_reference' on a server described as supporting 'multi-reference image fusion'; description is empty/uninformative.

Documented attack patterns abuse exactly the kind of access image_multi_reference gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Micu Image MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for image_multi_reference:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "image_multi_reference": {
      "limits": [
        {
          "counter": "image_multi_reference_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

image_multi_reference stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Micu Image MCP — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
