THE RISK

Low Risk

Why searxng_status needs a policy

This is a read-only status/health check operation. It queries the health endpoint of a SearXNG instance to determine reachability and responsiveness. No data is created, modified, deleted, or executed—only retrieved. The blast radius of misuse is minimal (information disclosure about service availability), warranting low severity.

From the tool's definition Tool name 'searxng_status' and description 'Check whether SearXNG is reachable and responding to healthz' indicate a health check query operation that retrieves status information without modifying data or triggering side effects.

How to control searxng_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 searxng_status:

policy.json

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

searxng_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.
