Delete message for everyone. Only works for messages from you (from_me=True), within ~48 hour window. Args: message_id, phone, instance_name, from_me. Returns: confirmation.
AI agents call delete_message to permanently remove resources in Automagik Tools — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes messages, which is an irreversible action that destroys data. Even though it has restrictions (only messages from the user within a ~48 hour window), the core functionality is destructive in nature. The fact that deletions are confirmed 'for everyone' amplifies the impact, as it affects other users' access to the message.
From the tool's definition The tool description explicitly states 'Delete message for everyone' and operates on message data that cannot be recovered. The tool is designed to irreversibly remove messages from a messaging platform.
Documented attack patterns abuse exactly the kind of access delete_message gives an agent:
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 delete_message:
{
"version": "1",
"default": "deny",
"hide": [
"delete_message"
]
}delete_message disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete message for everyone. Only works for messages from you (from_me=True), within ~48 hour window. Args: message_id, phone, instance_name, from_me. Returns: confirmation. It is categorised as a Destructive tool in the Automagik Tools MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Automagik Tools MCP server in PolicyLayer and add a rule for delete_message: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Automagik Tools. Nothing to install.
delete_message is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_message rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_message. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_message is provided by the Automagik Tools MCP server (namastexlabs/automagik-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Automagik Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
