broadcast_message · Telegram Bot MCP: Risk & Policy

WHAT IT DOES

What broadcast_message does on Telegram Bot MCP

AI agents use broadcast_message to create or update resources in Telegram Bot MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Telegram Bot MCP environment.

WHY IT NEEDS A POLICY

Why broadcast_message needs a policy

This tool sends messages to all known users simultaneously, which is a write operation (creating/sending messages) but with a very high blast radius — a single misuse could spam every user in the database. It does not delete data or move money, but the wide-scale, potentially irreversible social/reputational impact justifies a high severity rating.

Verdict

broadcast_message Rate-limited

broadcast_message 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.
