Announcing: A Smart Two-Way Bridge for Counter-Strike 1.6 and Discord!
Ever wanted to see what’s happening on your classic Counter-Strike 1.6 server right from Discord? Or maybe let your Discord community chat with players in-game, even if they’re not at their PC?
I’ve built a new Python bot that does just that, creating a seamless, two-way bridge between your CS 1.6 server and a designated Discord channel. It’s a lightweight, smart solution to keep your community connected.
What It Does: The Key Features
This isn’t just a simple log-dumper. It’s a smart bridge designed to be useful, not noisy.
- Smart Human Detection: This is the best part. The bot stays quiet and suppresses all server messages (like map changes or bot-only kills) when the server is empty. As soon as the first human player joins, the bot wakes up and starts relaying all activity. When the last human leaves, it goes quiet again. No more spamming your Discord channel when no one is playing!
- Two-Way Chat: Messages from Discord are sent directly into the in-game chat. In-game messages (
andsay) are relayed to Discord, complete with team icons (π΅/π΄) and even a tombstone emoji (πͺ¦) if the player is dead.say_team
- Full Game Event Reporting: Get real-time updates for all important events:
- Kills:
Player A killed Player B with an awp π₯
- Joins/Leaves:
π Player C joined the server
- Bomb Events:
π£ The bomb has been planted!
- Round/Win Events:
orπ Round started!π΄ Terrorists Win! (CT 5, T 2)
- Kills:
- GeoIP Player Flags: See where your players are from! The bot automatically looks up player IPs and assigns a country flag (e.g., π¨π¦, πΊπΈ). Bots get a π€ icon, and any failed human lookups get a π³οΈ.
How It Works
The bot is built on two simple principles:
- UDP Log Listener: You configure your CS 1.6 server to send its logs in real-time to the bot (using the
command). The bot listens on a port (default:logaddress_add), parses these logs, and formats them for Discord.8009
- Asynchronous RCON Client: When a user types a message in your Discord channel, the bot uses RCON (the server’s remote-control protocol) to send a
command to the game, broadcasting the message to all players.say
How to Set Up Your Own Bridge
Ready to try it? You’ll need a server (a simple VPS or even a home machine) to run the Python script.
Step 1: Get the Script & Install Dependencies
First, save the Python code above as
cs_discord_bridge.py
You’ll need Python 3 installed. Then, install the required Python libraries using pip:
Bash
pip install discord.py geoip2 tomli
(Note:
is used as a fallback for
tomli
on Python versions older than 3.11).tomllib
Step 2: Get the GeoIP Database
For the country flag feature, you need to download the free GeoLite2 Country database from MaxMind.
- Go to the MaxMind GeoLite2 free database page and sign up.
- Download the “GeoLite2-Country” database (it will be a
file)..mmdb
- Place this file (e.g.,
) on your server in a location the bot can access.GeoLite2-Country.mmdb
Step 3: Create Your
config.toml
config.toml
Next, create a file named
config.toml
Here is a template. You must fill in the required values.
Ini, TOML
# --- Required Settings ---
# Your Discord Bot Token (get from Discord Developer Portal)
discord_token = "YOUR_BOT_TOKEN_HERE"
# The ID of the Discord channel you want to bridge
discord_channel_id = "YOUR_CHANNEL_ID_HERE"
# Your Counter-Strike 1.6 server's IP or hostname
cs_host = "12.34.56.78"
# Your Counter-Strike 1.6 server's RCON port (usually the same as game port)
cs_port = 27015
# Your server's RCON password (from server.cfg)
cs_rcon_password = "YOUR_RCON_PASSWORD_HERE"
# --- Optional Settings ---
# Path to the GeoIP database you downloaded in Step 2
geoip_db = "/path/to/GeoLite2-Country.mmdb"
# The IP address for the bot to listen on.
# "0.0.0.0" is usually correct to listen on all available IPs.
listen_host = "0.0.0.0"
# The port for the bot to listen for CS logs on.
# This MUST match what you set in Step 4.
listen_port = 8009
# Set to 'true' to allow bot-on-bot kills and other bot-only
# activity to be posted even when no humans are on.
allow_bot_messages = false
# The prefix for bot commands in Discord (e.g., !players)
# The bridge will ignore messages starting with this.
discord_prefix = "!"
- To get a Bot Token: You need to create an “Application” in the Discord Developer Portal. Create a Bot, and be sure to enable the Message Content Intent under the “Bot” tab.
- To get a Channel ID: In Discord, enable Developer Mode (Settings > Advanced), then right-click your channel and select “Copy ID”.
Step 4: Configure Your CS 1.6 Server
Now, tell your Counter-Strike server to send its logs to your bot.
Add the following line to your server’s
server.cfg
autoexec.cfg
BOT_SERVER_IP
listen_port
config.toml
log on
logaddress_add BOT_SERVER_IP:8009
You will need to restart your server (or change maps) for this to take effect.
Step 5: Run the Bot!
You’re all set. Go to the directory with your script and config file and run:
Bash
python3 cs_discord_bridge.py
If all goes well, you’ll see console messages indicating it has logged into Discord and is listening for logs. Now, when you join your server, you should see the activity pop up in your Discord channel!
That’s it! You now have a smart, modern bridge to your classic CS 1.6 server. Feel free to grab the code and try it out.

cs_discord_bridge.py β Two-way Discord β Counter-Strike 1.6 bridge
Features:
- Chat relay (say, say_team) with tombstone for dead players
- Join / leave (posts leave messages always)
- Kill events (killer β victim, with flags, headshots)
- Suicide / world kills
- Bomb events (spawned, dropped, got, planted, defused, bombed) with π£ emoji
- Discord β CS chat via asynchronous RCON client
- Consistent GeoIP flags (π€ for bots, π³οΈ for failed human lookups)
- Enhanced debugging for shell command execution
- Round start/end and team win messages with scores
- Map change messages suppressed until human detected, re-suppressed when all humans leave
- Messages sent when human player (non-BOT SteamID) detected in logs
- Message suppression for non-disconnect events when no humans
Listen port set to 8008 for CS logs.
