RCON Command Tester
Run console commands without opening the game client. Confirm RCON works after setup or send a quick broadcast with say.
Connection goes through our server — your RCON port must be reachable from the internet, not just localhost. Password is sent over the wire; use a dedicated RCON password, not your admin login.
In server.properties: enable-rcon=true, rcon.port=25575, rcon.password=yourpassword — then restart the server.
Setting up RCON after first install
Add enable-rcon=true, rcon.port=25575, and rcon.password to server.properties. Restart fully. Test with list. Some hosting panels expose an RCON password that overrides the file.
RCON vs hosting panel console
Panel consoles attach to the server process directly. RCON is for external automation — restart scripts, Discord bots, monitoring. If this tester works, your bot will too.
Useful RCON commands to test with
| Command | What it does |
|---|---|
| list | Show online players and count |
| say Hello | Broadcast message to all players |
| save-all | Flush world data to disk |
| tps | Show TPS (Paper) |
| whitelist list | Print whitelisted players |
How to use this tool
- 1
Enable RCON in server.properties
Set enable-rcon=true, rcon.port=25575, and rcon.password to a strong unique password. Restart the server fully — RCON does not hot-reload.
- 2
Enter connection details
Host or IP reachable from the internet, RCON port (default 25575), password, and a command like list. Forward TCP 25575 if testing from outside your network.
- 3
Send and read the response
A successful list command returns online players. Empty or error responses mean wrong password, blocked port, or RCON disabled. Use the port checker on 25575 if connection fails.
Frequently asked questions
What is RCON in Minecraft?
RCON (Remote Console) sends server commands over TCP with a password, default port 25575. Useful for list, say, save-all, stop, and plugin commands from scripts or bots without joining the game.
How do I enable RCON on a Minecraft server?
In server.properties: enable-rcon=true, rcon.port=25575, rcon.password=<strong-password>. Restart the server. Restrict port 25575 by firewall to trusted IPs when possible.
Why does RCON connection fail?
RCON disabled, wrong password, wrong port, firewall blocking 25575, server still starting, or port not forwarded externally. Check port 25575 with the port checker first.
Is RCON secure for a public Minecraft server?
RCON has no encryption — password travels in plaintext. Use VPN, SSH tunnel, or IP-restricted firewall. Many hosts prefer panel consoles over public RCON.
What commands can I send via RCON?
Any console command: list, say, whitelist add, save-all, tps (Paper), spark. No tab completion. Large outputs may truncate.
What is the default RCON port?
25575 TCP — separate from gameplay port 25565. Set rcon.port in server.properties if you need a different port and forward that port instead.
Does RCON work while the server is starting?
RCON accepts connections only after the server finishes loading. During world generation or plugin startup, connections may time out — wait for "Done" in the console.
