[BUG] computer-use: "Cannot read properties of undefined (reading 'checkAccessibility')" on request_access

Preflight Checklist

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

What's Wrong?

The built-in computer-use MCP server shows as "connected" in /mcp, but every call to request_access fails with:

Cannot read properties of undefined (reading 'checkAccessibility')

Environment:

• Claude Code v2.1.87
• macOS Darwin 25.3.0 (Sequoia)
• Plan: Max
• Terminal has both Accessibility and Screen Recording permissions granted
• Restarted Claude Code multiple times, re-enabled computer-use via /mcp

What Should Happen?

Expected: macOS permission dialog appears to approve app access
Actual: JavaScript error before the dialog ever appears
