image_scale_by_percent

THE RISK

High Risk

The tool name suggests it scales/resizes an image by a percentage value. Based on sibling tools like 'image_scale_by_size' and 'image_round_corner', these appear to be image processing/transformation operations that execute multimedia processing on Qiniu Cloud. The description is empty, so confidence is low.

From the tool's definition Tool name 'image_scale_by_percent' with empty description; inferred from sibling tool 'image_scale_by_size' which suggests image transformation operations on Qiniu Cloud multimedia services.

HOW TO CONTROL IMAGE_SCALE_BY_PERCENT

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

policy.json

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

image_scale_by_percent 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 Qiniu MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
