Why groupsInviteLinkRevoke needs a policy

Revoking an invite link is irreversible in effect — the old link becomes permanently invalid and anyone who had it can no longer use it to join the group. This is a destructive, non-undoable action with high blast radius since it could disrupt legitimate users from joining a group.

How to control groupsInviteLinkRevoke

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "groupsInviteLinkRevoke"
  ]
}

groupsInviteLinkRevoke 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 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.
