--channels session disconnects when switching to agent view or opening multiple Claude Code sessions

Summary

Starting Claude Code CLI with --channels (e.g. for a Telegram MCP connection) and then either (a) switching to agent view in the CLI or (b) opening a second Claude Code CLI session causes the --channels session to break and MCP servers (e.g. Telegram) to disconnect.

Steps to Reproduce

1. Start Claude Code CLI with --channels flag (with at least one MCP server configured, e.g. Telegram)
2. Either:

• Switch to agent view in the Claude Code CLI, or
• Open a second Claude Code CLI session (any terminal window)

1. Observe that the --channels session breaks and MCP connections drop

Expected Behavior

Switching views or running concurrent CLI sessions should not affect active --channels sessions or cause MCP disconnections.

Actual Behavior

• Switching to agent view disconnects MCP servers mid-session
• Opening any additional Claude Code CLI session appears to break the --channels session
• Likely root cause: --channels binds to a single session context; a new session or view switch either steals the connection or creates a conflict

Environment

• Claude Code version: 2.1.139
• OS: Windows 11 Pro 10.0.26200
• MCP affected: Telegram (plugin:telegram)
