rcon-cli

rcon-cli is a small command-line client implemented in Go for sending commands to game servers that expose the RCON protocol. It can run single commands or operate interactively, and supports multiple connection types (RCON, telnet, web) depending on the game server.

Key Features

• Implements Source RCON protocol (and supports alternate connection types such as telnet and web where applicable).
• Two operation modes: single-command mode (execute one or multiple commands and exit) and interactive input-stream mode (REPL-like session).
• YAML-based configuration file (rcon.yaml) with named environments to store multiple server credentials and per-environment logging paths.
• Docker image provided for containerized usage and easy deployment.
• Cross-platform prebuilt binaries published in releases for common OS/architectures.
• CLI options for address, password, connection type, config path, environment selection, timeout, logging, and a skip-errors mode.
• Works with many games tested by the project (examples include Minecraft, Rust, CS:GO, Factorio, ARK, Project Zomboid, 7 Days to Die, Conan Exiles, TF2, V Rising, Palworld).

Use Cases

• Send administrative or diagnostic commands to a remote game server from scripts or CI jobs.
• Interactive server management for game administrators who prefer a terminal-based tool.
• Integrate into automation pipelines (containers or host scripts) to query server status, list players, or run maintenance commands.

Limitations and Considerations

• Protocol scope is limited to RCON (Source RCON) and specific alternate connection types; servers using other remote-control protocols (e.g., BattlEye-specific protocols) are not supported unless they expose a compatible interface.
• Some games require server-side flags or specific connection types (e.g., enabling web RCON for Rust or using telnet for certain titles); operator must configure the server accordingly.
• No graphical interface or web UI; tool is purely command-line oriented and intended for administrators comfortable with terminals.

rcon-cli is a focused, minimal CLI tool for remotely executing commands on RCON-capable game servers. It emphasizes simplicity, scriptability, and small operational footprint while providing configuration and Docker support for common deployment patterns.
