WHAT IT DOES

What check_rich_message does on Telegram Bot

AI agents call check_rich_message to retrieve information from Telegram Bot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_rich_message is rated Low

Even though check_rich_message only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs check_rich_message safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Telegram Bot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For check_rich_message, this is the rule to start with:

check_rich_message Allowed

check_rich_message is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "check_rich_message": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Telegram Bot, apply this rule, and every check_rich_message call is checked against it from then on.
