pymfp 1.0.0

Mirror Frame Protocol — symmetric frame envelope for LLM agent communication

MFP — Python Implementation

Production-ready Python implementation of the Mirror Frame Protocol

This is the reference Python implementation of MFP, a protocol for secure, peer-to-peer communication between autonomous agents. It provides end-to-end encrypted channels, federated message transport, and a minimal API for agent lifecycle management.

Protocol Specification: For the complete MFP protocol design and specification, see mfp-spec

Features

• Symmetric design — no client/server distinction, all agents are peers
• End-to-end encryption — AES-256-GCM AEAD with HMAC-SHA-256 key derivation
• Federation-ready — bilateral channels, recovery protocols, TCP transport
• Production hardening — circuit breakers, timeouts, health checks, metrics
• High performance — Merkle tree for O(log N) global state updates
• Library-first — runtime embeds in any Python process
• Standalone server — YAML-configured process for managing agents
• Type-safe — full type annotations with py.typed marker

Installation

pip install pymfp

Or install from source:

git clone https://github.com/Madahub-dev/MFP.git
cd MFP
pip install -e .

Quickstart

5-minute hello world between two agents:

from mfp import Runtime, RuntimeConfig, bind, mfp_send, mfp_channels

# Create a runtime
config = RuntimeConfig()
runtime = Runtime(config)

# Define two simple agent callables
# Each receives a DeliveredMessage and returns None
def alice(msg):
    print(f"Alice received: {msg.payload.decode()}")

def bob(msg):
    print(f"Bob received: {msg.payload.decode()}")

# Bind agents to the runtime
alice_handle = bind(runtime, alice)
bob_handle = bind(runtime, bob)

# Establish a channel between them (Layer 2 / admin operation)
channel_id = runtime.establish_channel(alice_handle.agent_id, bob_handle.agent_id)

# Send a message from Alice to Bob
receipt = mfp_send(
    alice_handle,
    channel_id=channel_id,
    payload=b"Hello from Alice!",
)

print(f"Message sent, receipt step: {receipt.step}")

# Shutdown
runtime.shutdown()

Run this script to see agents communicate through MFP channels.
