THE RISK

Low Risk

Why getSyncedMessageStats needs a policy

This tool retrieves statistical information about messages in a channel—a read-only query operation with no side effects. It does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal; an AI agent could only over-query or leak metadata about message counts/statistics, which poses low risk compared to other categories.

From the tool's definition Tool name 'getSyncedMessageStats' and description 'Returns summary statistics for stored messages in a channel' indicate a retrieval operation that queries and returns aggregated data without modification, deletion, or execution of external operations.

POLICY

How to control getSyncedMessageStats

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 getSyncedMessageStats:

policy.json

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

getSyncedMessageStats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
