What happened
Claude Code cannot connect to the Chrome extension. Every call to tabs_context_mcp (including with createIfEmpty: true) returns:
▎ Browser extension is not connected. Please ensure the Claude browser extension is installed and running, and that you are logged into claude.ai with
▎ the same account as Claude Code.
This persists across multiple retries.
Steps to reproduce
- Install/enable the Claude extension in Chrome
- In Claude Code, attempt any browser tool (e.g., tabs_context_mcp)
- Connection fails with the "not connected" message
Troubleshooting already tried
- Confirmed the extension is present and enabled at chrome://extensions
- Fully quit (Cmd+Q) and reopened Chrome
- Retried the connection multiple times
- Logged into claude.ai in Chrome with the same account as Claude Code
Expected
tabs_context_mcp returns the current tab group so browser automation can proceed.
Actual
Persistent "Browser extension is not connected" error; no tabs are ever returned.
