What list_servers does on Komodo

AI agents call list_servers to retrieve information from Komodo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

Why list_servers needs a policy

This tool retrieves and displays server information from the Komodo platform without creating, modifying, or deleting any resources. It is a straightforward read operation with minimal security risk unless the server list itself contains sensitive information, but the baseline classification is Read with low severity due to its read-only nature.

From the tool's definition Tool name is 'list_servers' and description states 'List all servers in Komodo.' The verb 'list' indicates a query operation that retrieves data without modification or side effects.

Documented attack patterns abuse exactly the kind of access list_servers gives an agent:

How to control list_servers

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_servers": {}
  }
}

list_servers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Komodo — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
