Describe the Bug

Where does the bug appear?
Cursor IDE (Desktop, macOS arm64), Browser Automation / team admin policy fetch

Description
Settings > Browser & Network shows “Unable to verify browser policy” under Browser Automation, and the agent has no browser tools: the built-in cursor-ide-browser server connects and registers 16 tools but is excluded from the agent’s catalog.

Logs show the cause. Every call to the team admin settings endpoint fails with a protobuf decode error, and the MCP service then fails closed on browser features:

[error] Connect error in unary AI connect
ConnectError: [internal] parse binary: illegal tag: field no 0 wire type 1
service: aiserver.v1.DashboardService
method: GetTeamAdminSettings (also GetTeamAdminSettingsOrEmptyIfNotInTeam)

[MCPService] Browser server skip reason changed: none -> browser_features_disabled
[MCPService] Server status update: cursor-ide-browser -> connected (toolCount: 16)

The error repeats continuously. No system proxy or VPN is configured.

Tried already, no effect: updating 3.15.6 → 3.15.19, full quit/restart, toggling Browser Automation off/on.

Steps to Reproduce

  1. Sign in with a team account
  2. Open Settings > Browser & Network: Browser Automation shows “Unable to verify browser policy”.
  3. Ask the agent to use the browser: no browser tools are available to it.
  4. Check window logs (exthost > anysphere.cursor-always-local > Cursor Structured Logs): repeated GetTeamAdminSettings ConnectError as above.

Expected Behavior

Team admin settings fetch succeeds, browser policy is verified, and cursor-ide-browser tools are available to the agent (our org has browser automation enabled in the admin dashboard).

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @Nick_McHenry Thanks for the detailed post and I’m sorry for the inconvenience here. We observed this bug internally and we fixed it. Nightly builds have the fix in place, but the stable builds do not yet have the fix in place. If you’d like to use a Nightly build you can go to Cursor Settings → Beta and switch to Nightly Update Access there and then Update Cursor. Should then work as expected. If you want to wait that is fine too, Stable build should land in the next few days.

Checking back in here. This should be resolved in the current Latest build. Please update Cursor from Cursor · Download or the in-app updater, then restart.

After that, Settings > Browser & Network should verify browser policy normally, and browser tools should show up for the agent. If you are already on Latest and still seeing “Unable to verify browser policy”, reply with the version from About Cursor and we can take another look.
