API for interacting with Agents that use the Agent Protocol

Project description

Agent Protocol - Python SDK

Reference implementation of the Agent Protocol in Python by the AI Engineers Foundation (AIEF). This SDK allows you to easily wrap your agent in a webserver compatible with the protocol - you only need to define the task and step handlers for your agent.

Installation

pip install agent-protocol

Then add the following code to your agent:

from agent_protocol import Agent, Step, Task


async def task_handler(task: Task) -> None:
    # TODO: Create initial step(s) for the task
    await Agent.db.create_step(task.task_id, ...)


async def step_handler(step: Step) -> Step:
    # TODO: handle next step
    if step.name == "print":
        print(step.input)
        step.is_last = True

    step.output = "Output from the agent"
    return step


if __name__ == "__main__":
    # Add the task handler and start the server
    Agent.setup_agent(task_handler, step_handler).start()

Customization

Database

By default, the SDK stores data in memory. You can customize the database by setting db to your own database object.

Agent.db = your_database

The database object must implement the methods from db.py.

Routes

You can also add your own routes to the server. For example:

from agent_protocol import Agent, router
from fastapi import APIRouter

my_router = APIRouter()


@my_router.get("/hello")
async def hello():
    return {"hello": "world"}

my_router.include_router(router)

task_handler = ...
step_handler = ...
Agent.setup_agent(task_handler, step_handler).start(router=my_router)

Testing

You can test the compliance of your agent using the following script:

URL=http://127.0.0.1:8000 bash -c "$(curl -fsSL https://agentprotocol.ai/test.sh)"

What this does is run a series of GET and POST requests against your agent to verify that it's compliant with the Agent Protocol.

Docs

You can find more info and examples in the docs.

Development

If you want to use the agent_protocol package from the cloned repository, you should be able to use poetry to set it up, like below.

git clone git@github.com:AI-Engineers-Foundation/agent-protocol.git
cd agent-protocol/sdk/python
poetry install
poetry run python examples/minimal.py

Feel free to open an issue if you run into any problems!
