Quarry is a Python library that implements the Minecraft protocol. It allows you to write special purpose clients, servers and proxies.

Use pip to install quarry:

$ pip install quarry

• Supports Minecraft 1.7 and 1.8
• Supports Python 2.7 and 3.2+
• Built upon twisted and cryptography
• Exposes base classes and hooks for implementing your own client, server or proxy.
• Implements the design of the protocol - packet headers, modes, compression, encryption, login/session, etc.
• Implements all packets in "init", "status" and "login" modes
• Does not implement most packets in "play" mode - it is left up to you to hook and implement the packets you're interested in.
