claude-code - 💡(How to fix) Fix [BUG] Claude in Chrome — MCP navigate blocks domains that are in "Your approved sites"

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• This is a single bug report (please file separate reports for different bugs)
• I am using the latest version of Claude Code

What's Wrong?

When I add a domain to Claude in Chrome settings → Permissions → "Your approved sites", the domain appears in the approved list (with a recent "Last used" timestamp), but mcp__Claude_in_Chrome__navigate calls to that domain still return "Navigation to this domain is not allowed".

I've verified the following:

The domain is clearly listed under "Your approved sites" in extension settings Chrome's chrome://extensions site access for the extension is set to "On all sites" I manually visited each domain in Chrome with the extension running (loads normally in the browser itself) I fully closed and reopened Chrome The issue persists across multiple sessions over the past month Affected domains in my testing (all listed as approved, all blocked from MCP navigation):

theverandahantigua.com stjamesclubantigua.com bluewaters.net www.royaltonresorts.com / royaltonresorts.com A different domain that is in the approved list (theescapeantigua.com) works correctly, so the bug appears to be inconsistent rather than universal.

Environment:

Claude in Chrome extension: v1.0.69 Browser: Chrome on Windows 11 Pro (10.0.22631)

What Should Happen?

When a domain is listed under "Your approved sites" in Claude in Chrome settings, MCP navigate calls to that domain should succeed and load the page — matching the behavior shown for domains that currently work. The approved-sites list and the MCP navigation guard should use the same source of truth.

Error Messages/Logs

Navigation to this domain is not allowed

This error is returned by every mcp__Claude_in_Chrome__navigate call to the affected domains, regardless of whether the domain appears in "Your approved sites" or has been manually visited in Chrome.

Steps to Reproduce

1. Install Claude in Chrome extension (v1.0.69) and sign in.

2. Open Claude in Chrome settings → Permissions → Your approved sites.

3. Add a domain to the approved list — e.g. theverandahantigua.com. Confirm it appears in the list.

4. In chrome://extensions, open the Claude extension and set Site access → On all sites.

5. Open a new tab in Chrome and manually navigate to https://theverandahantigua.com/. Confirm the page loads normally in the browser.

6. Fully close Chrome and reopen it.

7. From Claude (Desktop or Claude Code), invoke the MCP tool: mcp__Claude_in_Chrome__navigate url: https://theverandahantigua.com/ tabId: <id of an open tab in the current MCP tab group>

8. Observe: the call returns "Navigation to this domain is not allowed" even though the domain is in the approved list.

Additional notes:

• Reproduced consistently with these domains: theverandahantigua.com, stjamesclubantigua.com, bluewaters.net, www.royaltonresorts.com, royaltonresorts.com.
• A different approved domain (theescapeantigua.com) does not exhibit the bug — MCP navigation to it succeeds — so the approved-sites list works for some domains but not others.
• The issue has persisted for over a month across multiple extension updates, Chrome restarts, and re-additions of the domains.
