Why telegram-vote-poll needs a policy

This tool creates or modifies data (voting state) in a reversible manner. While it operates within a userbot context with elevated permissions, voting on a poll is fundamentally a Write operation—it changes state but doesn't delete or irreversibly destroy data.

From the tool's definition Tool description states 'Vote in a poll by option index' and 'retracts vote', indicating it modifies poll state and user voting records. The action is reversible (vote can be retracted via empty array), distinguishing it from destructive operations.

POLICY

How to control telegram-vote-poll

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-vote-poll:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "telegram-vote-poll": {
      "limits": [
        {
          "counter": "telegram-vote-poll_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

telegram-vote-poll stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
