What's Wrong?

The Claude in Chrome MCP tool (mcp__Claude_in_Chrome__navigate) can no longer navigate to library.libecity.com. It was working before but stopped at some point.

Error message:
Navigation to this domain is not allowed

Details:

• libecity.com (main domain) → accessible ✅
• library.libecity.com (subdomain) → blocked ❌
• x.com → also blocked ❌

Steps to reproduce:

1. Use Claude in Chrome MCP navigate tool
2. Try to navigate to https://library.libecity.com/
3. Error: "Navigation to this domain is not allowed"

Expected behavior:
Navigation should be allowed as it was previously. I was using this to automate article posting to the library.

What Should Happen?

Navigation to library.libecity.com should succeed, as it did previously. I was using this workflow to automate article posting to the Libecity knowledge library.
