How to control list_api_categories

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

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

list_api_categories 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 ConnectWise API Gateway MCP Server — 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.
