sourcewatch 0.0.9

A library to query information of Goldsrc and Source servers.

SourceWatch

A Python 3 library for querying information from Valve's GoldSrc and Source game servers. This library provides a complete implementation of the Server Queries protocol used by games like Counter-Strike, Half-Life, Team Fortress, and many others.

Features

• Support for both GoldSrc and Source engine servers
• Query server information, player lists, and server rules
• Ping measurement functionality
• Multi-packet response handling
• Modern Python 3.8+ support with type hints (Pydantic)
• MCP ready

Installation

Install SourceWatch using pip:

pip install sourcewatch

Quick Start

import SourceWatch

# Connect to a server
server = SourceWatch.Query('server.example.com', 27015)

# Get basic server information
info = server.info()
print(f"Server: {info['info']['server_name']}")
print(f"Map: {info['info']['game_map']}")
print(f"Players: {info['info']['players_current']}/{info['info']['players_max_slots']}")

# Get player list
players = server.players()
for player in players['players']:
    print(f"Player: {player['name']} (Score: {player['kills']})")

# Get server rules/settings
rules = server.rules()
for key, value in rules['rules'].items():
    print(f"{key}: {value}")

# Measure ping
ping = server.ping()
print(f"Ping: {ping}ms")

            "play_time": 1234.5
        },
        # ... more players
    ],
    "server": {
        "ip": "127.0.0.1",
        "port": 27015,
        "ping": 45.2
    }
}

rules()

Returns server configuration and rules.

Returns: Dictionary with server rules

{
    "rules": {
        "sv_gravity": "800",
        "mp_friendlyfire": "1",

        "ping": 38.7
    }
}

ping(num_requests=3)

Measures server response time by sending multiple info requests.

Parameters:

• num_requests (int, optional): Number of ping requests to average (default: 3)

Returns: Average ping in milliseconds (float)

Supported Games

Error Handling

The library raises SourceWatchError for various error conditions:

import SourceWatch

try:
    server = SourceWatch.Query('invalid-server.com')
    info = server.info()
except SourceWatch.SourceWatchError as e:
    print(f"Query failed: {e}")
except socket.timeout:
    print("Connection timed out")
except socket.gaierror:
    print("Could not resolve hostname")

Advanced Usage

Custom Timeout

# Set a custom timeout for slow connections
server = SourceWatch.Query('server.example.com', timeout=30)
