{

## Why post_telegram is rated Medium

This tool sends messages to a Telegram chat, which is a Write action (creating/posting content). Although the description says 'IRREVERSIBLY', the irreversibility here refers to the public visibility of the message once sent (it cannot be unsent or retracted automatically), not data destruction.

From the tool's own definition: "'send a message to a Telegram chat via YOUR bot token' and 'POSTS PUBLICLY & IRREVERSIBLY'"

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gateway:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "post_telegram": {
      "limits": [
        {
          "counter": "post_telegram_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
