telegram-mcp

The server loads Telegram API credentials from environment variables, which is good practice. It utilizes the Telethon library for API interaction. There are no explicit uses of `eval`, `exec`, or `os.system` for arbitrary code execution from user input found in the provided code. A critical security aspect is the `anon.session` file created locally, which stores session data; its compromise would grant access to the Telegram account. The `message` parameter in `send_message` is sent directly to Telegram, so an AI generating malicious markdown could potentially create annoying messages, but not execute code on the server itself. Overall, the direct code appears reasonably safe, but relies heavily on the security of the Telethon library and proper protection of the session file.
