Restart Claude Desktop.

Usage

After setup, you can ask Claude to:

• "Send a message to [contact name]"
• "What are my unread chats?"
• "Reply to the last message from [contact name]"

Style Guide (Optional)

Create src/mcp_telegram/convostyle.txt to help Claude match your texting style:

I text casually with friends, formally with work contacts.
I use emojis sparingly and prefer short messages.
