LibreFang Python SDK
Official Python client and SDK for the LibreFang Agent OS.
Installation
pip install librefang
Two Packages
This package provides two different interfaces:
1. REST API Client (librefang.client)
Control LibreFang remotely via its REST API.
from librefang import Client
client = Client("http://localhost:4545")
# Create an agent
agent = client.agents.create(template="assistant")
print(f"Agent created: {agent['id']}")
# Send a message
reply = client.agents.message(agent["id"], "Hello!")
print(reply)
# Stream a response
for event in client.agents.stream(agent["id"], "Tell me a story"):
if event.get("type") == "text_delta":
print(event["delta"], end="", flush=True)
2. Agent SDK (librefang.sdk)
Write Python agents that run inside LibreFang.
from librefang import Agent
agent = Agent()
@agent.on_message
def handle(message: str, context: dict) -> str:
return f"You said: {message}"
agent.run()
Or use the simple input/output functions:
from librefang import read_input, respond
data = read_input()
result = f"Echo: {data['message']}"
respond(result)
