What's Wrong?

First observed: mid-March 2026 | Duration: 6+ weeks
Related issues: #48806, #52367, #24593

The Claude in Chrome extension cannot connect to Claude Desktop. Error shown:

"Check your Claude in Chrome account — The Chrome extension needs to be signed in with the same account as Claude Desktop."

Both apps are signed into the same account. This dialog has never not appeared.

Why this is server-side (not local)
The switch_browser MCP tool broadcasts a connection request and waits up to 2 minutes for the user to click Connect. No dialog appears on my machine. The broadcast is not reaching my extension at all.

Separately: the Control Chrome MCP (non-Anthropic infrastructure) successfully lists tabs in the same Chrome session that Claude in Chrome cannot reach. The local Chrome install is fully operational. The failure is isolated to bridge.claudeusercontent.com.

Client-side work completed
Full Chrome uninstall/reinstall including all profile data, caches, preferences, and saved state. Single native messaging host present (com.anthropic.claude_browser_extension.json). No conflicting hosts, no enterprise policies, no VPN, no interfering extensions. Issue persists across every rebuild.

Support status
Anthropic support has acknowledged in writing that this requires "a human agent with backend access to investigate the bridge pairing state." No engineer has acted on it in 6+ weeks. Latest response sent was a generic remote MCP server / firewall template unrelated to the Chrome extension bridge.

What Should Happen?

Server-side reset of the bridge pairing state for my account. Support ticket has stalled — posting here to reach the team that owns the Chrome extension bridge infrastructure directly.
