THE RISK

Low Risk

Why get_server needs a policy

This tool retrieves information about an MCP server from a registry. It performs a lookup/query operation without modifying, deleting, or executing any external operations. The low severity reflects that even if misused, it can only expose metadata about servers, not compromise systems or trigger actions.

From the tool's definition Tool name is 'get_server' and description states 'Get detailed information about a specific MCP server from the PulseMCP Sub-Registry.

POLICY

How to control get_server

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

policy.json

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

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