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)
