"What did I miss on Telegram today?" sounds like the perfect question for an AI assistant. As of November 2026, neither Claude nor ChatGPT has a built-in Telegram connector, and most Telegram integrations you will find don't answer that question at all. Here is why, and what works.
Telegram has two very different APIs:
To catch up on your own chats, you need the second one.
Several open-source MCP servers use the user API. They work, but you create your own API credentials on my.telegram.org, run the server yourself, keep the session file safe, and they usually only run in desktop clients that can launch local processes. Check their tool list too: some expose sending and mark-as-read.
Fezola (disclosure: I work on it) connects your own Telegram account to a remote MCP server, next to your mailboxes and Google Chat, with a few deliberate constraints:
What the assistant gets:
list_recent_telegram: messages received in private chats and, in groups, the ones that mention you or reply to you, since a given time. Each item says whether it is unread and whether you wrote in that chat since (repliedAfter), which is what makes "what still needs my answer?" possible.list_telegram_chats: your conversations (people, groups, channels), most recently active first, with unread and mention counts.search_telegram: Telegram's own search, across all chats or inside one. get_telegram_chat: read a conversation, oldest first, and page back. https://api.fezola.com/mcp.
