Why convert_markdown_to_html needs a policy

This tool takes markdown input and produces HTML output. It is fundamentally a data transformation utility that creates new formatted content. While the output could theoretically be used destructively (e.g., injected into a webpage), the tool itself simply performs format conversion without executing code, accessing sensitive data, or modifying external systems.

From the tool's definition Tool description states 'Convert Markdown to HTML', which is a text transformation that creates or modifies data (HTML output) from input (Markdown).

How to control convert_markdown_to_html

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 convert_markdown_to_html:

policy.json

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

convert_markdown_to_html 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.
