THE RISK

Low Risk

Why caddy_status needs a policy

This tool retrieves and reports operational status metrics (API reachability, site count, TLS/ACME state) without creating, modifying, deleting, or executing any actions. It is a read-only diagnostic query. Severity is low because the information exposed is non-sensitive operational state that does not expose credentials or secrets, and misuse cannot cause system damage or data loss.

From the tool's definition Tool name 'caddy_status' and description 'Report Caddy status: admin-API reachability, number of configured sites, and TLS/ACME summary' indicates retrieval of status information only.

POLICY

How to control caddy_status

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 caddy_status:

policy.json

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

caddy_status 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.
