Why kick-chat-member needs a policy

Kicking a user is a destructive, hard-to-reverse action: the user is expelled from the chat and their membership is terminated. While a re-invite is theoretically possible, the action itself cannot be automatically undone and has significant social/operational impact. This qualifies as Destructive rather than Write because it removes access/membership rather than modifying data.

From the tool's definition 'Kick a user from a group, a supergroup or a channel' — forcibly removes a user from a chat, which is an irreversible removal action (the user loses access and must be re-invited).

POLICY

How to control kick-chat-member

PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram Bot MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for kick-chat-member:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "kick-chat-member"
  ]
}

kick-chat-member 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 Telegram Bot 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.
