What probably matters to youSection of the release

Unclear It is not clear whether the earlier check covered any case besides deniedMcpServers.

What

Claude in Chrome is the browser integration, delivered as a built-in MCP server (MCP is a standard for connecting outside tools). Organizations that deploy a managed MCP configuration, managed-mcp.json, take exclusive control of which MCP servers run, and that used to block Claude in Chrome with no way to allow it.

  • A new device policy key, allowClaudeInChromeWithManagedMcp, is off by default. When it is true and the enterprise configuration was read without fatal errors, Claude in Chrome can run alongside managed-mcp.json. deniedMcpServers and the organization's Claude in Chrome setting can still block it.
  • Without the key, trying to configure Chrome is refused with a Chrome-specific message: "Claude in Chrome is blocked by your organization's managed MCP configuration (managed-mcp.json). An administrator can allow it with allowClaudeInChromeWithManagedMcp in device policy." Before, it got the generic "You cannot dynamically configure MCP servers when an enterprise MCP config is present" message.
  • The prompt offering to install or set up Claude in Chrome is now also skipped when managed-mcp.json blocks Chrome. Before, only deniedMcpServers was checked.
  • Starting Remote Control with --chrome under a blocking policy now prints the specific reason Chrome is blocked, followed by "Start Remote Control without --chrome." It used to print one fixed message naming both an enterprise MCP config and a deniedMcpServers entry.

Why

Administrators using managed-mcp.json can now opt in to Claude in Chrome. Where it stays blocked, people are no longer offered a setup that cannot work, and error messages name the policy responsible.
