THE RISK

Medium Risk

Why generate_svg_placeholder needs a policy

This tool creates new SVG content (reversible write operation). It does not execute code, delete data, move money, or trigger external systems. The output is a generated image file/string that can be modified or discarded. Severity is low because SVG placeholders are benign, non-destructive artifacts with minimal blast radius if misused by an agent.

From the tool's definition Tool description states 'Generate SVG placeholder images' — the verb 'generate' indicates creation of new data (SVG content). SVG placeholders are images, not code execution or external operations.

POLICY

How to control generate_svg_placeholder

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_svg_placeholder": {
      "limits": [
        {
          "counter": "generate_svg_placeholder_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_svg_placeholder 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.
