[BUG] MCP Telegram plugin drops initial messages requiring duplicates to register

Bug Description
Hi Anthropic Team,

Hope you're doing well. I wanted to reach out about an issue I've been experiencing with the MCP Telegram channel plugin for Claude Code.

When I send messages to Claude via Telegram, they sometimes don't get picked up on the first try. I end up having to send the same message twice before Claude registers it and responds. It doesn't happen every time, but it's frequent enough to be noticeable.

My setup:

• Claude Code CLI with the MCP Telegram plugin
• Telegram Bot API
• macOS, with the session running continuously

I've attached a screenshot showing the duplicate messages in the chat.

I'd really appreciate any guidance or a fix for this. Happy to share logs or any other info that might help.

Thank you for your time and support!

Best,
