PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram MCP Complete, 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.
