Protolink is a lightweight Python framework designed for the development of autonomous agents that leverage large language models (LLMs), facilitating native Agent-to-Agent (A2A) communication. Ideal for building distributed multi-agent systems, Protolink simplifies the integration of various tools while managing context and communication between agents with minimal boilerplate.

Key Features

• Autonomous, LLM-Powered Agents: Build agents that can communicate with each other directly, manage execution context, and integrate tools seamlessly.
• Agent-to-Agent Communication: Compliant with Google’s A2A specification, Protolink extends traditional A2A communication by providing enhanced LLM and tool integration capabilities.
• Dynamic Semantic Context Injection: Automatically enriches agent prompts with downstream capabilities, allowing them to adapt their behavior in real-time without being tightly coupled.
• Structured Flows: The latest update introduces Structured Flows, enabling users to define complex workflows for agents that can be executed deterministically within a unified framework.
• Flexible Architecture: With a centralized agent architecture, Protolink allows for individual components to be used independently or combined as needed, enhancing modularity and maintainability.

Simplified Agent Creation

Protolink emphasizes a straightforward API that encourages rapid development. Below is a brief example of creating an agent with Protolink:

from protolink.agents import Agent

# Initialize & start the Registry for A2A Discovery (optional)
from protolink.discovery import Registry
registry = Registry(url="http://127.0.0.1:9000", transport="http")
registry.start(background=True)

# Define the agent card
agent_card = {
    "url": "http://127.0.0.1:8020",
    "name": "example_agent",
    "description": "A dummy agent",
}

# Initialize the agent
agent = Agent(card=agent_card, transport="http", registry=registry)

# Start the agent.
agent.start()

Production-Ready Solutions
