Tools (30)

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

  • execute_script

    Execute a script; this is only available to the our mcp-app

  • get_cpu_informationGet CPU informationread-only

    Get CPU information.

  • get_disk_usageGet disk usageread-only

    Get detailed disk space information including size, mount points, and utilization.

  • get_execution_detailsGet the execution details with request ID

    Get the execution details with request ID

  • get_hardware_informationGet hardware informationread-only

    Get hardware information such as CPU details, PCI devices, USB devices, and hardware information from DMI.

  • get_journal_logsGet journal logsread-only

    Get systemd journal logs.

  • get_listening_portsGet listening portsread-only

    Get details on listening port, protocols, and services.

  • get_memory_informationGet memory informationread-only

    Get detailed memory including physical and swap.

  • get_network_connectionsGet network connectionsread-only

    Get detailed information about active network connections.

  • get_network_interfacesGet network interfacesread-only

    Get detailed information about network interfaces including address and traffic statistics.

  • get_process_infoProcess detailsread-only

    Get information about a specific process.

  • get_service_logsGet service logsread-only

    Get recent logs for a specific systemd service.

  • get_service_statusGet service statusread-only

    Get detailed status of a specific systemd service.

  • get_system_informationGet system informationread-only

    Get basic system information, including operating system, distribution, kernel version, uptime, last boot time, PCP installation and service status, and historical PCP time ranges.

  • list_block_devicesList block devicesread-only

    List block devices on the system

Show 15 more tools
  • list_directoriesList directoriesread-only

    List directories under a specified path with various sorting options.

  • list_filesList filesread-only

    List files under a specified path with various sorting options.

  • list_processesList processesread-only

    List running processes

  • list_servicesList servicesread-only

    List all systemd services.

  • pcp_guideRead the PCP metrics guideread-only

    Returns the PCP metrics guide: a catalog of the metric names recorded on a typical Linux system, and how to read the values the other PCP tools return. Read it before investigating performance with PCP, and take metric names from it rather than from memory.

  • pcp_list_metricsList available PCP metricsread-only

    Browses the PCP metric namespace. Lists the metrics under 'prefix' with their descriptions, collapsing any large sub-namespace to one line giving its name and how many metrics it holds; call again with that name as the prefix to see inside it. Only metrics this system's pmlogger records are listed, so everything listed can be passed to pcp_query_metrics. The pcp_guide tool already names the commonly needed metrics, so reach for this when you need a subsystem the guide does not cover. Use only if get_system_information() indicates PCP is available.

  • pcp_performance_summaryGet PCP performance summaryread-only

    Produces a condensed snapshot of CPU, memory, disk, network, and process information using pcp xsos. Can summarize the live system or a particular time in the past. Use only if get_system_information() indicates PCP is available.

  • pcp_query_metricsQuery PCP historical metricsread-only

    Retrieves historical metric data from PCP archives as JSON samples. When start_time, end_time, or interval is omitted, reasonable defaults are chosen, targeting one hour or about 20 samples. Call pcp_guide first for the metric catalog and how to read the values; do not guess metric names. Use only if get_system_information() indicates PCP is available.

  • read_fileRead fileread-only

    Read the contents of a text file up to a safe size limit.

  • read_log_fileRead log fileread-only

    Read a specific log file.

  • reject_script

    Reject a script; this is only available to the our mcp-app

  • run_scriptRun a scriptread-only

    Call this tool to run a previously validated script. Use this when validate_script returned needs_confirmation: false.

  • run_script_interactiveRun a script with interactive user confirmationcan change or delete data

    Run a script that modifies the system. The user will be asked for approval interactively. A bash script should be used for simple operations that can be expressed cleanly as a few shell commands, but a Python script should be used if complex processing is needed. Bash scripts are run with strict mode (set -euo pipefail) applied by the invocation, so handle expected non-zero exit codes in the script (e.g. with `|| true`) where needed. Write short, simple scripts that are easy to review - do not include unnecessary complexity such as elaborate logging or handling unlikely corner cases.

  • run_script_with_confirmationRun a script with confirmationcan change or delete data

    Call this tool to run a previously validated script that modifies the system. Use this when validate_script returned needs_confirmation: true. The parameters must match those passed to validate_script.

  • validate_scriptValidate a scriptread-only

    Request validation of a script from the gatekeeper. The tool will return a unique token that must be included in the run_script tool call.
