[BUG] computer-use MCP server not appearing in /mcp on Max plan (CLI, macOS)

Description

The computer-use built-in MCP server does not appear in the /mcp server list, despite meeting all documented requirements.

Environment

• Claude Code version: 2.1.87 (latest)
• Platform: macOS (Darwin 25.3.0, Apple Silicon)
• Auth method: claude.ai OAuth login
• Subscription: Max plan (subscriptionType: "max")
• Session type: Interactive (not -p mode)

Steps to Reproduce

1. Run claude to start an interactive session
2. Run /mcp to open the MCP server list
3. Look for computer-use in the list

Expected Behavior

Per the computer use documentation, the computer-use built-in MCP server should appear in the /mcp list for Pro/Max users on macOS with v2.1.85+.

Actual Behavior

The computer-use server does not appear at all. Only 9 other MCP servers are listed (exec-utm, figma, claude.ai memory, Notion, Twitter Bridge, utm, context7, github, telegram).

Investigation

After digging into the binary, I found that the feature is gated behind a Statsig feature gate (tengu_malort_pedway), which defaults to enabled: false. The code, including the full ComputerUseSwift library, is present in the binary — it's just not being activated server-side for this account.

Question

Is computer use still in limited rollout? The blog post and documentation suggest it should be available to all Pro/Max users. When can we expect full availability?
