computer-use MCP fails on macOS Tahoe 26 — "Cannot read properties of undefined (reading 'checkAccessibility')"

Bug Description

The computer-use MCP server reconnects successfully but all tool calls fail with:

Cannot read properties of undefined (reading 'checkAccessibility')

The native accessibility bridge module appears to fail silently on macOS 26, returning undefined instead of the expected native object.

Environment

• Claude Code version: 2.1.90
• Claude desktop app version: 1.2.234
• macOS version: 26.3.1 (a) — Build 25D771280a
• Kernel: Darwin 25.3.0 arm64 (Apple Silicon — T6041)
• Architecture: ARM64

Steps to Reproduce

1. Run Claude Code 2.1.90 on macOS 26.3.1
2. Open Claude desktop app (1.2.234)
3. Connect the computer-use MCP via \/mcp\
4. Call any computer-use tool (e.g. \request_access\, \screenshot\)

Expected Behavior

Tool calls succeed, accessibility permission dialog appears.

Actual Behavior

Every call returns: \Cannot read properties of undefined (reading 'checkAccessibility')\

Notes

• macOS Accessibility and Screen Recording permissions are granted for Claude
• The MCP server connects (shows as "connected") but the native \.node\ bridge module fails to initialize
• Likely the native binary was not compiled for Darwin 25.x / macOS 26
