POLICY

How to control list_conversation_inboxes

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

policy.json

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

list_conversation_inboxes 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 Frontapp 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.
