THE RISK

Low Risk

Why get_html needs a policy

This tool retrieves and returns HTML markup from a webpage—a read-only operation with no side effects. It does not execute scripts, modify data, delete resources, or commit financial transactions. The blast radius is minimal; misuse would only expose publicly accessible HTML content. Confidence is high because the description is explicit and unambiguous.

From the tool's definition Tool name 'get_html' and description 'Get the HTML code of a webpage for a specified URL' indicate retrieval of static web content with no modification or execution of code.

POLICY

How to control get_html

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_html": {}
  }
}

get_html is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
