Channel plugin MCP server silently fails to start on restart

Description

When Claude Code is restarted (either manually or via a .bat script), the channel plugin's MCP server (bun process) sometimes fails to start silently. Claude Code launches with the correct --channels plugin:telegram@claude-plugins-official flag, but no bun/MCP process is spawned. Telegram messages stop coming through.

Steps to reproduce

1. Install the Telegram channel plugin: /plugin marketplace add anthropics/claude-plugins-official
2. Start Claude Code with --channels plugin:telegram@claude-plugins-official --dangerously-skip-permissions
3. Verify Telegram channel is working
4. Close Claude Code window
5. Restart Claude Code with the same command
6. Telegram channel no longer works — no bun/MCP processes are running

Observed behavior

• Claude Code process is running with the correct --channels argument (confirmed via Win32_Process.CommandLine)
• installed_plugins.json shows the plugin is installed correctly (version 0.0.4, valid install path)
• Plugin is not in blocklist.json
• bun is available and can manually start the MCP server (bun run --shell=bun --silent start in the plugin directory works fine)
• No bun/node/MCP-related processes exist — the plugin's MCP server was never spawned
• /plugin UI does not show the installed Telegram/Discord plugins under "Installed" tab — only shows claudeai plugins
• No error messages or logs indicating the failure

Workaround

Reinstalling the plugin marketplace resolves the issue:

/plugin marketplace add anthropics/claude-plugins-official

However, this is required after nearly every restart, which is not sustainable for a 24/7 agent setup.

Expected behavior

Channel plugins should reliably start their MCP servers on every Claude Code launch when --channels flag is provided, or at minimum surface an error if initialization fails.

Environment

• Claude Code: v2.1.83
• OS: Windows 11 Pro for Workstations
• Bun: v1.3.11
• Plugin: telegram@claude-plugins-official v0.0.4
• Launch method: .bat script and Windows Task Scheduler (auto-start on boot)

Additional context

This is a recurring issue on a VM running Claude Code as a 24/7 Telegram agent. The health check script detects Claude Code process as running (since the main process is alive), but the channel plugin is non-functional. This creates a silent failure mode where the agent appears healthy but cannot receive messages.
