claude-code - 💡(How to fix) Fix Telegram plugin MCP connection drops after each conversation turn

Bug Report

Description

When running claude --channels plugin:telegram@claude-plugins-official, the Telegram MCP plugin connection (plugin:telegram:telegram) repeatedly disconnects after processing a conversation turn. This causes the bot to become unresponsive to new messages until the session is restarted.

Environment

• Claude Code v2.1.150
• macOS Darwin 25.3.0
• Plugin: telegram@claude-plugins-official v0.0.6
• Started via: tmux new-session -d -s claude-tg "claude --channels plugin:telegram@claude-plugins-official"

Reproduction Steps

1. Start Claude Code with Telegram channel: claude --channels plugin:telegram@claude-plugins-official
2. Send a message to the bot via Telegram
3. Bot receives and processes the message successfully
4. After Claude Code finishes its turn and returns to idle prompt (❯), check /mcp status
5. plugin:telegram:telegram shows ✘ failed
6. Subsequent Telegram messages are not received by the Claude Code session

Observed Behavior

• The MCP connection is ✔ connected immediately after startup
• After processing 1-2 messages (especially if tool use is involved like WebSearch), the connection drops to ✘ failed
• The bun polling process (bun server.ts) continues running but messages are not routed to the Claude session
• Restarting the tmux session restores connectivity temporarily

MCP Status Before/After

# After startup (working):
plugin:telegram:telegram · ✔ connected · 4 tools

# After processing a message (broken):
plugin:telegram:telegram · ✘ failed

Other MCP servers that also fail in the same session

• composio · ✘ failed
• plugin:github:github · ✘ failed

Workaround

Kill and restart the entire tmux session after each disconnection. This is not sustainable for a continuously running bot.

Frequency

Happens consistently — reproduced ~6 times in a single session (2025-05-25). The connection typically drops within 1-2 minutes of processing a message.
