WHAT IT DOES

What send_photo_file does on Telegram Mcp Kit

WHY IT NEEDS A POLICY

Why send_photo_file needs a policy

Sending a photo file to a Telegram chat creates new data/content that persists and is visible to recipients. This is reversible (the message can be deleted by edit_message or delete_message tools also present), making it Write rather than Destructive. Severity is high because an AI agent could spam, harass, or send inappropriate images to unintended recipients or chats, causing reputational and operational damage.

From the tool's definition Tool name 'send_photo_file' indicates sending/uploading a photo file to Telegram. Server description states 'message sending' and 'file handling' as core capabilities.
