Telegram channel plugin MCP connection drops after Bash tool use (macOS Intel)

Description

The official Telegram channel plugin (telegram@claude-plugins-official) loses its MCP connection immediately after a Bash tool call. The plugin subprocess dies silently — no error output, no crash log. Messages received before the first Bash call work perfectly; the disconnect is reproducible every time.

Reproduction steps

1. Start Claude Code with the Telegram channel plugin:

``bash
claude --channels plugin:telegram@claude-plugins-official --dangerously-skip-permissions --continue
``

1. Send a message via Telegram — Claude receives it and replies successfully
2. Send 2-3 more messages — all work fine
3. Send a message that triggers a Bash tool call (e.g., "give me today's date and exact time down to the millisecond")
4. Claude runs the Bash command successfully, but when it tries to reply via the plugin, the MCP connection is gone:

``
Error: No such tool available: mcp__plugin_telegram_telegram__reply
``

What I've tried

• Commented out the orphan watchdog (server.ts lines 657-664, the process.ppid check) — same crash
• Swapped bun for Node/tsx as the plugin runtime (modified .mcp.json in the plugin cache) — same crash
• Both confirm the issue is not in the plugin's shutdown logic or bun specifically — it's in how Claude Code manages the MCP connection during Bash tool execution.

Expected behavior

The Telegram plugin MCP connection should survive Bash tool calls.

Environment

• Claude Code: 2.1.98
• macOS 14.3.1 (Sonoma)
• Hardware: MacBook Pro 2019, Intel Core i7-9750H (x86_64)
• Bun: 1.3.13 (latest available for Intel Mac)
• Node: v25.9.0
• Plugin version: 0.0.6 (telegram@claude-plugins-official)

Notes

• A friend running the same plugin on Linux reports no issues — this may be Intel Mac-specific
• The plugin works flawlessly for pure text exchanges (no tool calls). It consistently dies on the first Bash tool invocation
• No error output appears in the terminal when the plugin disconnects — it's completely silent
