BACpypes3 - Python library for BACnet applications
BACpypes provides a BACnet application layer and network layer written in Python for daemons, scripting, and graphical interfaces. This version is the next generation for Python3.8+, completely overhauled from the Python2.5+ version using async/await methods and asyncio for communications.
MCP (Model Context Protocol) integration
The bacpypes3.mcp module exposes the BACpypes3 CLI commands (whois,
read, write, rpm, wirtn, BBMD ops, …) as MCP tools with natural names
(who_is, read_property, write_property, read_property_multiple,
who_is_router_to_network, …). It has three personalities:
- Importable library. Each tool is a plain
asyncfunction returning JSON-serializable Python values. Inject anApplicationand call the tools directly. - Stand-alone MCP server.
python -m bacpypes3.mcp <BACpypes flags>builds anApplicationviaSimpleArgumentParserand serves the tools over stdio usingmcp.server.mcpserver.MCPServer(renamed fromFastMCPin the mcp 2.x SDK; BACpypes3 requiresmcp>=2). - Embedded server. A long-running BACnet server can inject its own
Applicationand startmcp.serve_http(...)as a concurrent asyncio task, so an LLM agent can drive it over HTTP without fighting the host application's stdout. Seesamples/mini-device-with-mcp.pyfor the reference pattern.
The mcp and pydantic packages are declared as an optional extra and are
only imported when a server is actually built; the tool functions are usable
without them:
pip install -e ".[mcp]" # to run the server
