Claude Code CLI connecting to Chrome MCP returns "not connected" despite extension showing as connected

Environment:

• macOS 14 (Sonoma/Sequoia)
• Claude Code CLI (latest)
• Chrome with Claude extension installed
• Single claude.ai account (xxxx@email.com — same account in extension and Claude Code

Steps to reproduce:

1. Install Claude browser extension
2. Set extension to "On All Sites" via Chrome extension permissions
3. Launch claude from terminal in a project directory
4. Confirm /mcp panel shows claude-in-chrome · ✓ connected
5. Confirm /chrome dialog shows Status: Enabled, Extension: Installed, Enabled by default: Yes
6. Call any mcp__claude-in-chrome__* tool (e.g., tabs_context_mcp)

Expected: Tool returns tab context / connects successfully

Actual: Tool returns:
Browser extension is not connected. Please ensure the Claude browser extension is installed and running
(https://claude.ai/chrome), and that you are logged into claude.ai with the same account as Claude Code.

Notes:

• Only one Claude account in use — no account mismatch possible
• Chrome restarted after extension install
• Claude Code restarted
• /mcp panel contradicts the tool error by showing the extension as connected
• "Reconnect extension" option in /chrome dialog does not resolve it
• Extension site access set to "On All Sites"
