Why log_short needs a policy

This tool queries and presents debugging or execution context information (stack visualization) with no side effects. It is a passive inspection tool typical of development debugging utilities. No data is created, modified, deleted, or executed—only retrieved and displayed.

From the tool's definition Tool name 'log_short' and description 'View current stack visualization' indicate a read-only operation that retrieves and displays stack information without modifying any state.

POLICY

How to control log_short

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

policy.json

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

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