THE RISK

Low Risk

Why dozzle_container_url needs a policy

This tool constructs a URL pointing to a container's Dozzle log viewer. It only builds/returns a URL string — a read/query operation with no side effects. No data is modified, executed, or deleted. Severity is low since generating a URL has minimal blast radius.

POLICY

How to control dozzle_container_url

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

policy.json

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

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

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