Chrome Extension shows "Connected" but Claude Code cannot connect

Environment:

• Windows 11 Build 26200.7623
• Claude Code: 2.1.27
• Chrome Extension: 1.0.41

Problem:
The Chrome extension shows "Connected" status, but when running Claude Code and calling tabs_context_mcp, it returns
"Browser extension is not connected."

Steps tried:

• Restarted Chrome
• Reloaded extension
• Reinstalled extension
• Killed all Claude processes and restarted
• Only one Claude Code instance running
• Problem persists for several days
