What's Wrong?
Title:
--chrome flag: "No Chrome extension connected" despite Chrome, extension, and native host all running
Body:
## Environment
- Claude Code CLI on Windows 11 Pro (10.0.26200)
- Chrome running with Claude extension active
- chrome-native-host.exe confirmed running via tasklist
- Started with: claude --dangerously-skip-permissions --chrome "run precrime"
## Bug
Every mcp__claude-in-chrome__tabs_context_mcp call returns "No Chrome extension connected" despite:
- Chrome is open with tabs active
- The Claude Chrome extension is installed and showing as connected in the browser
- chrome-native-host.exe process is running
- The --chrome flag was passed at launch
Tried 15+ calls across tabs_context_mcp, tabs_create_mcp with various parameters. Same error every time. No recovery path available from
within the session.
This has recurred across multiple sessions over multiple days on Windows 11.
## Expected
Chrome tools should connect when --chrome is passed and the extension is active.
## Steps to Reproduce
- Install Claude Chrome extension
- Open Chrome, verify extension is active
- Launch Claude Code CLI with --chrome flag
- Call any mcp__claude-in-chrome__ tool
- Get "No Chrome extension connected" error every time
What Should Happen?
Claude should connect to the open chrome window and not argue with me
