THE RISK

Medium Risk

Why send-photo needs a policy

The tool sends data (a photo message) to a chat, modifying the chat's message history. This is a Write operation because: (1) it creates new content in a persistent medium (Telegram chat), (2) the action is reversible (messages can be deleted), and (3) it does not execute arbitrary code, delete data, or transfer funds.

From the tool's definition Tool name 'send-photo' and description 'Send photo with caption' indicate it creates/transmits a new message artifact (photo) to a specified chat. This is a reversible write operation—the message can be deleted afterward.

POLICY

How to control send-photo

PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram Bot MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for send-photo:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "send-photo": {
      "limits": [
        {
          "counter": "send-photo_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

send-photo 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 Telegram Bot 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.
