genai-protocol 2.0.3

A universal agents connector library that integrates with GenAI.works infrastructure

GenAI Agent Protocol

GenAI Agent Protocol is an async‑first Python framework for building WebSocket‑based AI agents that let you:

• Connect an agent to the GenAI.works ecosystem
• Process messages via registered handler functions
• Upload and retrieve files with contextual metadata (agent_context)
• Log messages with contextual metadata (agent_context)

✨ Features

🧠 Agent Binding: Decorator-based agent registration
🪝 WebSocket Communication: Bidirectional messaging with a central server
📁 File Manager: Async file upload/download & metadata fetch
🪵 Context Logger: Structured, contextual WebSocket-based logging
🔎 OpenAI Schema Conversion: Automatically converts Pydantic-type function signatures to OpenAI-compatible schemas
📞 Agent‑to‑agent calls: invoke another registered agent from within your handler

📚 Core Concepts

⚙️ Environment Variables Setup

Before you run the GenAI Agent Protocol, make sure to configure the necessary environment variables.

You can do this by creating a .env file in your project root or exporting them directly in your terminal session.

Required:

AGENT_JWT_TOKEN="<your JWT token from GenAI CLI or UI>"

Defaults (you can override if needed):

ROUTER_WS_URL=ws://localhost:8080/ws           # WebSocket router URL
BACKEND_API_BASE_URL=http://localhost:8000     # Backend API URL
IS_LOCAL_SETUP=true                            # Flag to indicate local development

If your agent logic requires additional environment variables, just add them to the .env file or terminal session the same way.

GenAISession

A central controller that registers agents and manages the event lifecycle.

from genai_session.session import GenAISession

genai_session = GenAISession()

@bind(...)

Registers a handler function with the session and make them visible to GenAI infrastructure.

from genai_session.session import GenAISession
from genai_session.utils.context import GenAIContext

genai_session = GenAISession()

@genai_session.bind(name="test_name", description="Test Description")
async def message_handler(agent_context: GenAIContext, parameter: str) -> str:
    ...

GenAIContext

Provides contextual info (agent_uuid, request_id, etc.), a logger, and access to the FileManager.

from genai_session.session import GenAISession
from genai_session.utils.context import GenAIContext

genai_session = GenAISession()

@genai_session.bind(name="test_name", description="Test Description")
async def message_handler(agent_context: GenAIContext, parameter: str) -> str:
    request_id = agent_context.request_id

Files

Handles file uploads (save) and retrievals (get_by_id, get_metadata_by_id).

from genai_session.session import GenAISession
from genai_session.utils.context import GenAIContext

genai_session = GenAISession()

@genai_session.bind(name="txt_content_reader_agent", description="Agent returns txt file content")
async def get_file_content(agent_context: GenAIContext, file_id: str) -> str:
    file = await agent_context.files.get_by_id(file_id)
    file_metadata = await agent_context.files.get_metadata_by_id(file_id)
    ...

Logger

Sends JSON logs through WebSocket with severity levels (debug, info, warning, error, critical).

from genai_session.session import GenAISession
from genai_session.utils.context import GenAIContext

genai_session = GenAISession()

@genai_session.bind()
async def reverse_name(agent_context: GenAIContext, name: str) -> str:
    """Agent reverses the name"""
    agent_context.logger.info("Inside the reverse_name function")
    agent_context.logger.debug(f"name: {name}")
    ...

Invoke Agent from Agent

You can invoke another agent from within an agent using the genai_session.send method (this method is working ONLY in IS_LOCAL_SETUP=true).
This method takes the agent_uuid and params as arguments.

from genai_session.session import GenAISession
from genai_session.utils.context import GenAIContext
from genai_session.utils.agents import AgentResponse

genai_session = GenAISession()

@genai_session.bind()
async def invoke_another_agent(agent_context: GenAIContext, name: dict) -> str:
    """Agent invokes another registered agent"""
    agent_response: AgentResponse = await genai_session.send(
        agent_uuid="agent_uuid", # you can get UUID from - await agent_context.get_agents()
        params={
            "username": name,
            "interests": ["python", "genai"],
            "age": 30,
        } # key is a parameter name, value is the value you want to pass
    )
    response = agent_response.response
    is_success = agent_response.is_success
    ...

@session.bind(name="get_weather_agent", description="Get weather forecast data")

) -> dict[str, Any]:

    agent_context.logger.info("Inside get_translation")
    params = {"q": city_name, "dt": date, "key": API_KEY}

    return {"weather_forecast": response.json()["forecast"]["forecastday"][0]["day"]}

🚀 Running the Event Loop

Start your agent's event loop:

async def main():
    await genai_session.process_events()

if __name__ == "__main__":
    import asyncio
    asyncio.run(main())
