ComputerPilot MCP v0.7.1 - Windows Console Shutdown Reliability

ComputerPilot MCP v0.7.1 is a focused patch release for Windows console shutdown behavior after the v0.7.0 Adaptive Execution Router release.

The patch does not add or remove MCP tools, change workflow schemas, alter execution-router policy, or change the cross-platform capability contract. It fixes the Windows launcher/supervisor interrupt path so intentional console shutdown is graceful on the first Ctrl+C and promptly forceable on the second.

Highlights

Graceful first Ctrl+C

  • Run the live ComputerPilot bootstrap through the virtual-environment Python process rather than keeping PowerShell in the live process chain after environment creation.
  • Let the Supervisor receive Windows console interrupts directly.
  • Treat the first Ctrl+C as an intentional graceful stop request.
  • Preserve lifecycle drain/stop coordination instead of immediately killing the runtime.
  • Prevent an intentional exit code 130 / Windows Ctrl+C termination from entering the launcher crash-restart loop.

Prompt forced shutdown on the second Ctrl+C

  • Track console interrupt count inside the Supervisor.
  • Let a second Ctrl+C set an explicit force-stop signal.
  • Abort a long runtime drain/stop wait when force-stop is requested.
  • Shorten process cleanup waits during a forced shutdown so the operator can exit promptly.
  • Record whether shutdown cleanup was forced in the drain result.

Signal-path safety

  • Use a re-entrant Supervisor lock for the console-shutdown path so a signal arriving while the main thread is already inside lock-protected lifecycle code cannot deadlock itself.
  • Install the SIGINT handler only from the main thread and restore the previous handler during Supervisor teardown.
  • Keep scripts.bootstrap and scripts.supervisor in one Python process for the live start path so console control signals are not obscured by an intermediate PowerShell process.

Compatibility

  • Public package/project identity remains computerpilot-mcp / ComputerPilot MCP.
  • Protocol-level MCP server identifier remains ali_windows_agent_mcp.
  • Windows full-profile catalog remains 150 unique tools.
  • deterministic-v1 routing behavior from v0.7.0 is unchanged.
  • Workflow schema remains v6.
  • Semantic Browser, Native Documents, durable jobs, recovery, workflows, and existing tool profiles are unchanged.
  • Linux/macOS portable-core behavior is unchanged; this patch targets the Windows console launcher and Supervisor interrupt path.

Packaging contract

v0.7.1 publishes deterministic packages for:

  • computerpilot-mcp-v0.7.1-windows-amd64.zip
  • computerpilot-mcp-v0.7.1-linux-amd64.tar.gz
  • computerpilot-mcp-v0.7.1-linux-arm64.tar.gz
  • computerpilot-mcp-v0.7.1-macos-amd64.tar.gz
  • computerpilot-mcp-v0.7.1-macos-arm64.tar.gz
  • SHA256SUMS.txt

Release archives continue not to vendor upstream Secure MCP Tunnel or Cloudflared binaries. Managed tunnel runtimes remain selected/downloaded/verified independently by the existing runtime-management path.

Linux arm64 and macOS amd64 remain deterministic package/updater targets without a dedicated native hosted-runner execution claim. Windows amd64, Linux amd64, and macOS arm64 continue to receive native hosted validation through the repository release gates.

Validation expectations

The patch release is gated by:

  • focused Windows launcher/bootstrap/Supervisor regression tests;
  • full pytest;
  • Ruff;
  • mypy;
  • compileall;
  • launcher validation / Full Doctor;
  • deterministic five-target packaging and checksum verification;
  • CI on Windows, Linux, and macOS for Python 3.10 and 3.12;
  • Platform Release Validation on Windows, Linux, and macOS for Python 3.12;
  • Release Packaging Smoke.

See docs/V0.7.1-VALIDATION.md for the recorded release evidence.

Known limits

  • The first Ctrl+C requests graceful shutdown, so a mutation-aware drain may still take bounded time when work is active. Pressing Ctrl+C again requests the force-stop path.
  • This patch does not introduce new visual-grounding, external-MCP extension, or delegated-browser capabilities. Those remain future roadmap work.
