THE RISK

Low Risk

Why playwright_get_persistence_stats needs a policy

This tool only retrieves statistical information about persisted sessions; it has no side effects, does not modify or delete data, and does not execute code or trigger external operations. It is purely informational, making it a Read category risk with low severity since misuse would only expose metadata about session persistence rather than enabling harmful actions.

From the tool's definition Tool name and description indicate a statistics retrieval operation: 'Get statistics about persisted sessions on disk'. The verb 'get' and the focus on gathering information about existing sessions without modification confirms a read-only operation.

POLICY

How to control playwright_get_persistence_stats

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

policy.json

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

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