send_photo · Telegram Mcp Kit MCP: Risk & Policy

WHAT IT DOES

What send_photo does on Telegram Mcp Kit

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

WHY IT NEEDS A POLICY

Why send_photo needs a policy

send_photo writes/creates new data (a photo message) to a Telegram chat. While messages can technically be deleted later, the primary action is content creation, placing it in the Write category rather than Execute (which would apply if the tool triggered arbitrary external operations).

From the tool's definition Tool description states 'Send a photo to a chat' — this creates new content (a message with photo attachment) in a chat, modifying the chat's message history irreversibly from the perspective of undo operations, but the action is not destructive in the sense…

Verdict

send_photo Rate-limited

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.
