Why convert_list needs a policy

This tool transforms data between different textual representations of lists. It performs a pure conversion/transformation operation with no side effects, no data persistence, no execution of commands, and no destructive actions. It is essentially a text-processing utility similar to other read/transform tools on this server.

From the tool's definition Convert between different list formats (comma-separated, line-separated, etc.)

POLICY

How to control convert_list

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

policy.json

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

convert_list 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 IT Tools 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.
