Surge CLI Updates

Surge CLI has been expanded with comprehensive management and diagnostics commands across Surge Mac, Surge iOS, and Surge tvOS.

Surge CLI has been significantly expanded into a comprehensive command-line management and diagnostics interface, with the following new commands:

New Commands

  • Added status to display the active profile and its full path, outbound mode, feature states, uptime, and version information.
  • Added version to display Surge, Core, Controller protocol, operating system, and device versions.
  • Added dump summary to provide a passive overview of the current network environment, including interfaces, IP addresses, default router, DNS servers, cellular or Wi-Fi information, and configuration warnings.
  • Added mode to view or switch between Rule, Direct, and Global Proxy modes.
  • Added global-policy to view or change the policy used in Global Proxy mode.
  • Added policy-group to list policy groups, inspect their current selections, manually select a policy, or clear an automatic-group override.
  • Added profile to list, inspect, validate, and switch profiles. Profile listing and validation are available on macOS.
  • Added module to list modules and enable or disable multiple modules in one operation.
  • Added feature to inspect and control MitM, Rewrite, Scripting, HTTP Capture, Packet Capture, and Cellular Mode. On macOS, it also supports System Proxy and Enhanced Mode.
  • Added device to list Gateway Mode devices or inspect an individual device by identifier or MAC address on macOS.
  • Added reconnect-device to reconnect a specified access-point client from the command line on macOS.
  • Added script list to display configured scripts and script run to execute a cron script by name, including disabled scripts, while returning its output or exception.
  • Added log to retrieve up to 10,000 recent log lines from either the persistent log file or the more detailed in-memory log.
  • Added log watch to continuously stream newly generated, unfiltered logs.
  • Added logbook to display recent structured Logbook records.
  • Added script-log to retrieve the log from a specific script execution.
  • Added benchmark encryption to measure the encryption and decryption performance of the device running Surge, with correctness, integrity, and tamper-detection checks.

Diagnostic Improvements

Existing diagnostic commands have also been improved:

  • proxy-runtime-status now provides detailed runtime information for Tailscale and WireGuard, including traffic, recent errors, peer handshakes, DERP connections, Exit Node state, peer paths, and MagicDNS information.
  • Query and diagnostic commands now produce structured, human-readable terminal output by default, while --raw remains available for automation.
  • Commands that change settings now return the resulting state and properly report failures. System Proxy and Enhanced Mode commands wait for the actual state transition to complete.
  • Remote Controller passwords can now be supplied through a secure terminal prompt, SURGE_CLI_PASSWORD, or --password-stdin, avoiding exposure in the process command line.
  • Remote connections now support bracketed IPv6 addresses and include timeouts for stalled connections and finite operations.
  • Interactive mode now supports quoted arguments and backslash escaping.

Availability

The above updates apply to Surge Mac 6.8.0, Surge iOS 5.21.0, and Surge tvOS 5.21.0. Please notice surge-cli can operate remote instances via --remote.

The corresponding updates have also been added to the AI Skills documentation. After the update, AI Agents can automatically gain the new capabilities.
