Desktop Commander MCP - Pros & Cons
Pros
- ✓Uses your existing Claude Desktop or Cursor subscription — no marginal API cost
- ✓Actually runs terminal commands and streams output, not just filesystem calls
- ✓Native Excel, PDF, and DOCX support is rare in MCP servers
- ✓Docker isolation option makes it usable on shared machines
- ✓Works across virtually every MCP-compatible client with one config
Cons
- ✗Giving AI real terminal access is a security decision — audit and restrict carefully
- ✗Command blocklist can miss creative agent workarounds without careful tuning
- ✗Companion desktop app is still in beta on macOS and Windows
- ✗In-memory code execution shares host resources — no full sandbox by default
- ✗Remote MCP mode adds latency compared to the local server
Code Airlock - Pros & Cons
Pros
- ✓Real security boundary at the microVM level — not just agent-side prompts
- ✓Host repo stays read-only; every change comes back as a reviewable git commit
- ✓Multi-agent: swap between Claude Code, Codex, OpenCode with one flag
- ✓Sandbox never needs GitHub creds — PRs push from the host
- ✓MIT licensed with npm/Homebrew/curl installs and preflight `doctor` diagnostics
Cons
- ✗Requires Docker Sandboxes and KVM/virtualization on the host
- ✗No MCP integration — wraps agents but doesn't extend their tool surface
- ✗Extra latency vs. running the agent directly on the host
- ✗Small project (thin wrapper) — you're also depending on the underlying sbx CLI
- ✗Adds cognitive load: another layer between you and the agent
