Tools (20)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • cancel_execution

    Request local cancellation. Windows confirms Job Object tree termination asynchronously; failures remain unknown.

  • cancel_remote_batch

    Stop dispatch of queued targets; active targets become unknown, not confirmed terminated.

  • control_service

    Start, stop, or restart a Windows service (requires the MCP host process to have sufficient privileges).

  • delete_output_log

    Delete a session log by opaque handle.

  • execution_status

    Read a local execution state. Unknown after restart means no automatic replay or verified ownership.

  • get_service

    Get detailed status of one Windows service by name.

  • list_services

    List Windows services, optionally filtered by a name pattern. Returns Name, DisplayName, Status.

  • read_execution_output

    Read a bounded base64 output page, including while running.

  • read_output_log

    Read a bounded raw byte page from an opt-in session log; base64 encoded. Handles are process-local and expire after one hour.

  • remote_batch_status

    Read ordered per-target batch records; unavailable after process restart.

  • run_powershell

    Run a PowerShell script/command on this Windows host in a hidden process (no console window appears). Returns stdout, stderr and exit code. Use for any Windows command, file, or system task.

  • run_program

    Run a native executable DIRECTLY (no shell) in a hidden process and capture clean stdout/stderr + exit code. Use this for console programs like gh, git, docker, node, python, etc. -- direct execution captures their stdout/stderr without PowerShell pipeline semantics. Historical hidden-shell native stdout loss is executable/environment-specific; it is not universal. Provide the program and an args array (no shell quoting needed).

  • runtime_capabilities

    Read-only runtime package, protocol, supported and available engines, transports and limits; no identity, environment or secrets.

  • sftp_download

    Download a file from a remote host to this Windows host over SFTP, in-process (ssh2 — no scp.exe, no WSL, headless).

  • sftp_upload

    Upload a local file to a remote host over SFTP, in-process (ssh2 — no scp.exe, no WSL, headless). Use to deploy scripts/configs to Linux hosts.

  • ssh_exec

    Run a command on a remote host over SSH, fully in-process (no ssh.exe, no WSL — works headless). Use for Linux hosts or any OpenSSH target. Auth via privateKeyPath or password. Returns stdout, stderr, exit code.

  • start_execution

    Start a local executable directly with durable idempotency and bounded output. No shell; remote targets unsupported.

  • start_remote_batch

    Opt-in process-local SSH/WinRM batch; 1–32 explicit targets, up to 8 concurrent, per-target deadline. No discovery or retry. SSH supports at most four explicit jumps. Unknown after server restart.

  • system_info

    Return OS, CPU, memory and disk summary for this Windows host.

  • winrm_exec

    Run a command on a remote Windows host via PowerShell Remoting (WinRM / Invoke-Command). Native to Windows Server — no SSH server or agent needed on the target, only WinRM enabled. Output captured in-process (no console window).
