THE RISK

Why telegram-delete-topic needs a policy

This tool permanently removes a forum topic and its entire message history, which is an irreversible destructive action. The blast radius is high because an AI agent misusing this could erase important conversations and historical data from a user's Telegram forum without recovery. While not as severe as account-level destruction, the permanent loss of data classifies it as Destructive rather than Write.

From the tool's definition "Delete a forum topic and all its message history" — the tool irreversibly deletes data (topic and all associated messages) that cannot be recovered.

POLICY

How to control telegram-delete-topic

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-Telegram, and nothing reaches the server without passing your rules. This is the rule we recommend for telegram-delete-topic:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "telegram-delete-topic"
  ]
}

telegram-delete-topic disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register MCP-Telegram — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
