send_document · Telegram Mcp Kit MCP: Risk & Policy

WHAT IT DOES

What send_document does on Telegram Mcp Kit

AI agents use send_document 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_document needs a policy

send_document performs a Write action: it transmits and stores a document in a Telegram chat, creating new data on the platform. While the document could theoretically be deleted later via delete_message, the tool itself is not destructive—it adds content reversibly.

From the tool's definition Tool description states 'Send a document/file to a chat' — this creates new content (a file upload) in a remote Telegram chat, modifying the chat state irreversibly from the perspective of the chat history.
