Why numbers_super_resolution needs a policy

This tool runs an AI processing operation (super resolution upscaling) on an image, which constitutes executing an external computation/transformation. It modifies image data by upscaling it, but this is an active operation/process rather than a simple write. The 'Execute' category fits best as it triggers an external AI operation whose effects depend on the input image.

POLICY

How to control numbers_super_resolution

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "numbers_super_resolution": {
      "limits": [
        {
          "counter": "numbers_super_resolution_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

numbers_super_resolution 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.

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

FAQ

Questions about numbers_super_resolution

What does the numbers_super_resolution tool do? +

Upscale an image using AI Super Resolution (Creator Studio only). Increases resolution while preserving quality. It is categorised as a Execute tool in the Iwork MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on numbers_super_resolution? +

Register the Iwork MCP server in PolicyLayer and add a rule for numbers_super_resolution: 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 Iwork. Nothing to install.

What risk level is numbers_super_resolution? +

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

Can I rate-limit numbers_super_resolution? +

Yes. Add a rate_limit block to the numbers_super_resolution 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 numbers_super_resolution completely? +

Set action: deny in the PolicyLayer policy for numbers_super_resolution. 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 numbers_super_resolution? +

numbers_super_resolution is provided by the Iwork MCP server (reichenbach/iwork_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Iwork tool call.

Start from Iwork, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
