computer-use built-in MCP server missing from /mcp on macOS Tahoe, Claude Code 2.1.92 (Max plan)

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: 2.1.92 (standalone install via ~/.local/share/claude/versions/2.1.92)
• OS: macOS Tahoe (Darwin 25.4.0)
• Plan: Claude Max
• Auth: claude.ai (first-party, not Bedrock/Vertex/Foundry)
• Session: Interactive (not -p flag)

Steps to reproduce

1. Launch Claude Code in a terminal (claude)
2. Run /mcp
3. Look for computer-use in the server list

Expected behavior

computer-use should appear as a built-in MCP server (enabled or disabled) in the /mcp list.

Actual behavior

computer-use does not appear at all. Only User MCPs (claude-peers, paper, pencil), Local/Project MCPs, and claude.ai integrations (Gmail, Google Calendar, Notion) are listed. No "Built-in" section exists.

Computer use is enabled in the Desktop app and works there. The CLI does not surface the server.

Related issues

• #43307 — same symptom (computer-use missing from /mcp), reported on v2.1.91
• #43547 — native module path hardcoded to CI build machine, making computer-use non-functional in npm CLI distribution
• #41538 — checkAccessibility undefined on macOS Tahoe even when server does appear

This may be the same root cause as #43547 (missing native module in the distribution), but filing separately since the install method differs (standalone vs npm).
