THE RISK

Low Risk

Why find_chats needs a policy

This tool performs a read-only operation that queries and returns existing chat data from WhatsApp. It has no capability to create, modify, delete, or execute actions. The only parameter is 'instance_name' which specifies which WhatsApp instance to query. While the data returned could be sensitive (chat metadata), the tool itself is non-destructive and causes no side effects.

From the tool's definition Tool retrieves and lists existing chat conversations without modifying data. Description states 'Find all chat conversations' and 'Returns: list of chats with details' - purely a query/retrieval operation.

POLICY

How to control find_chats

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

policy.json

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

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