Why telegram-edit-topic needs a policy

This tool modifies (Write) forum topic properties including name, icon, and open/closed/visibility status. While reversible, the severity is elevated from medium to high because: (1) the MCP server operates as a userbot with full account access, meaning misuse could affect all topics the user has access to; (2) closing/hiding topics could disrupt communication in shared forums; (3) unauthorized modifications could…

From the tool's definition Tool description states it can "rename, change icon emoji, open/close, or show/hide" a forum topic. These are reversible modifications that alter topic metadata and visibility state without deleting data or executing arbitrary code.

POLICY

How to control telegram-edit-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-edit-topic:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "telegram-edit-topic": {
      "limits": [
        {
          "counter": "telegram-edit-topic_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

telegram-edit-topic 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.

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.
