[BUG] mcp.notification() call is missing

What's Wrong?

I tried to send a message with the telegram bot and claude doesn't receive it. Below is the debug log from claude:

⏺ The entire pipeline works:

1. Telegram delivers messages to the bot API ✅
2. Bot token is valid ✅
3. Bot can send messages back ✅
4. Your user ID is on the allowlist ✅

The only broken link is: the plugin's mcp.notification() call → Claude Code's channel handler. This is the internal MCP stdio notification path.

This could be a Claude Code version issue — channel notifications may require a newer version. You're on 2.1.81 (installed Mar 31).

• Plugin: telegram@claude-plugins-official v0.0.4
• Claude Code: 2.1.81 (Homebrew)
• Symptom: MCP tools (reply, react) work fine. Inbound notifications/claude/channel from the plugin never surface in the conversation.
• Verified: Bot polling works, messages reach the bot API, user is on allowlist, single instance running (no 409 conflict).

What Should Happen?

claude responds to telgram bot properly

Error Messages/Logs

⏺ Send a message to the bot now — I'm polling directly.                                                                                                                                                                                         
                                                                                                                                                                                                                                             
⏺ Got it — your message (/check) came through from Telegram. The bot token and polling work fine.

⏺ I can't reload plugins from bash — please type /reload-plugins in the prompt to restart the Telegram bot process.                                                                                                                             
                                                                                                                                                                                                                                                
  As for the issue: since the bot receives messages and tools work, but channel notifications don't surface, this is likely a bug in Claude Code 2.1.81's channel notification handling. I'd recommend filing an issue at

  - Plugin: telegram@claude-plugins-official v0.0.4

  - Symptom: MCP tools (reply, react) work fine. Inbound notifications/claude/channel from the plugin never surface in the conversation.                                                                                                        
  - Verified: Bot polling works, messages reach the bot API, user is on allowlist, single instance running (no 409 conflict).

Steps to Reproduce

1. configure telegram bot
2. complete pairing
3. try to send a message from telegram
