Connect compatible AI assistants to your own registered and authorized Windows or macOS computers for file operations, terminal commands and device management. Free: 1 device, 10,000 MCP tool calls per month; allowance resets next month.
Scored across 18 tools
Each tool targets a distinct resource and action (files, processes, services, devices, platform), with descriptions explicitly cross-referencing related tools (e.g. list_processes -> kill_process). Minor overlap exists because run_command can subsume file/service operations, and service_control's query/status overlaps list_services, but boundaries remain clear.
Nearly all names follow a snake_case verb_noun pattern (create_directory, delete_path, move_path, write_file, list_*). A few read-only tools use noun phrases (file_info, device_system_info, platform_status) instead of a verb, a small but noticeable deviation.
18 tools for cross-platform remote device management (files, processes, services, devices, setup) is reasonable, and each tool maps to a real operation. It sits at the upper edge of comfortable, but nothing feels redundant.
File lifecycle (list/info/read/write/create/move/delete), process (list/kill), service (list/control) and device (list/pair/setup/status) coverage is solid. Gaps: no device deregistration/rename, no process start (though run_command covers it), and no dedicated file search, all of which agents can work around.
Approve a pending device enrollment after the account owner independently confirms the 8-digit pairing code shown by the local device. code is the displayed one-time code. Changes trusted device registration; the backend validates account and quota. Do not guess codes.
Inputs: code (required).
Create a directory at path on the specified registered, authorized online device. device_id selects the target computer; path is a path on that computer. Mutates its filesystem; inspect existing paths and ensure the destination is correct.
Inputs: path (required), device_id (required).
Delete a remote file or directory from a registered, authorized online device. device_id identifies the target; path is the item to remove; recursive defaults to true for directory trees. Destructive, potentially irreversible. Inspect file_info or list_files and confirm before use.
Inputs: path (required), device_id (required), recursive.
Read OS and hardware system information from the specified registered, authorized and currently online device. device_id must come from list_devices. Read-only; cannot inspect an offline or unbound device.
Inputs: device_id (required).
Retrieve filesystem metadata about a remote file or directory. device_id identifies an authorized online device; path identifies an item on it. Read-only. Use before move_path, delete_path or write_file to inspect the target.
Inputs: path (required), device_id (required).
Terminate a process by its integer pid on a registered, authorized online device identified by device_id. Mutates process state and may interrupt applications or lose unsaved work. Verify target and PID using list_processes before use.
Inputs: pid (required), device_id (required).
List the devices registered to this DNS-DATA account. Returns device_id, device name, platform, connection and online state. Use a returned device ID as device_id for other tools. Read-only; account-specific.
Inputs: no named parameters.
List directory entries on an authorized, online remote device. device_id identifies a registered device; path is the directory path on that device, not on the MCP server. Read-only; inspect file_info for a specific entry.
Inputs: path (required), device_id (required).
List running processes and their identifiers on a registered, authorized online Windows or macOS device. device_id identifies the target. Read-only. Use the PID from results when calling kill_process.
Inputs: device_id (required).
List Windows Services or macOS launchd jobs on the registered, authorized online device identified by device_id. Read-only. Returned service names can be passed to service_control.
Inputs: device_id (required).
Move or rename a remote file or directory on a registered, authorized online device. device_id identifies the target; source is the existing path and destination is the new path. overwrite defaults to false; when true it may replace existing data. Destructive if overwriting; confirm paths.
Inputs: source (required), device_id (required), destination (required), overwrite.
Inspect DNS-DATA platform status for the authenticated account, including subscription limits, monthly tool-call allowance, usage and device quota. No device_id required. Read-only; does not execute on a remote device.
Inputs: no named parameters.
Read the text content of a UTF-8 file on an authorized, online remote device. device_id identifies the target; path is its local file path. max_chars limits the returned text to 1–200000 characters (default 200000). Read-only; not suitable for binary files.
Inputs: path (required), device_id (required), max_chars.
Execute a shell command on a registered, authorized online device. device_id selects target, command is the command line, shell selects powershell/pwsh/cmd (Windows) or zsh/bash/sh (macOS); macOS -root shells need a local helper. Optional working_directory; timeout_seconds clamped to 1–1800 (default 120). Can modify system or files; confirm consequential commands.
Inputs: command (required), device_id (required), shell, timeout_seconds, +1 more.
Query, start, stop or restart an OS service on the specified registered, authorized online device. device_id selects target, name identifies the Windows Service or macOS launchd job. action is query/status/start/stop/restart; timeout_seconds is clamped to 1–300 (default 30). Mutating actions can disrupt connectivity.
Inputs: name (required), action (required), device_id (required), timeout_seconds.
Get Apple Silicon macOS setup information, official download URL and npm launcher command for pairing a new DNS-DATA device. Returns instructions only; does not execute installation or pair hardware. The launcher window controls the online session.
Inputs: no named parameters.
Get Windows x64 setup information, official download URL and npm launcher command for pairing a new DNS-DATA device. Returns instructions only; does not execute installation, pair hardware or consume a new device slot.
Inputs: no named parameters.
Write UTF-8 content to a remote file on an authorized online device. device_id chooses the device, path the local target and content the text. mode is 'rewrite' (default, replaces content) or 'append' (adds content). Mutates stored data; verify destination before use.
Inputs: path (required), content (required), device_id (required), mode.
