THE RISK

Why sicry_check_tor needs a policy

This tool only queries the state of the Tor service to confirm it is operational before other operations proceed. It retrieves information (Tor status) without modifying, executing external commands, deleting data, or moving funds. The read-only nature and negligible blast radius if misused by an agent (worst case: false status report) place it in the Read category with low severity.

From the tool's definition Tool name 'sicry_check_tor' and description 'Verify Tor is running' indicate a status check operation with no side effects.

POLICY

How to control sicry_check_tor

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

policy.json

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

sicry_check_tor 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 Sicry — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
