Get Started with Microsoft Agent Framework for Python Developers
Quick Install
We recommend two common installation paths depending on your use case.
1. Development mode
If you are exploring or developing locally, install the entire framework with all sub-packages:
pip install agent-framework --pre
This installs the core and every integration package, making sure that all features are available without additional steps. The --pre flag is required while Agent Framework is in preview. This is the simplest way to get started.
2. Selective install
If you only need specific integrations, you can install at a more granular level. This keeps dependencies lighter and focuses on what you actually plan to use. Some examples:
# Core only
# includes Azure OpenAI and OpenAI support by default
# also includes workflows and orchestrations
pip install agent-framework-core --pre
# Core + Azure AI integration
pip install agent-framework-azure-ai --pre
# Core + Microsoft Copilot Studio integration
pip install agent-framework-copilotstudio --pre
# Core + both Microsoft Copilot Studio and Azure AI integration
pip install agent-framework-microsoft agent-framework-azure-ai --pre
This selective approach is useful when you know which integrations you need, and it is the recommended way to set up lightweight environments.
Supported Platforms:
- Python: 3.10+
- OS: Windows, macOS, Linux
1. Setup API Keys
Set as environment variables, or create a .env file at your project root:
OPENAI_API_KEY=sk-...
OPENAI_CHAT_MODEL_ID=...
...
AZURE_OPENAI_API_KEY=...
AZURE_OPENAI_ENDPOINT=...
AZURE_OPENAI_CHAT_DEPLOYMENT_NAME=...
...
AZURE_AI_PROJECT_ENDPOINT=...
AZURE_AI_MODEL_DEPLOYMENT_NAME=...
You can also override environment variables by explicitly passing configuration parameters to the chat client constructor:
from agent_framework.azure import AzureOpenAIChatClient
client = AzureOpenAIChatClient(
api_key='',
endpoint='',
deployment_name='',
api_version='',
)
See the following setup guide for more information.
2. Create a Simple Agent
Create agents and invoke them directly:
import asyncio
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient
async def main():
agent = Agent(
client=OpenAIChatClient(),
instructions="""
1) A robot may not injure a human being...
2) A robot must obey orders given it by human beings...
3) A robot must protect its own existence...
Give me the TLDR in exactly 5 words.
"""
)
result = await agent.run("Summarize the Three Laws of Robotics")
print(result)
asyncio.run(main())
# Output: Protect humans, obey, self-preserve, prioritized.
3. Directly Use Chat Clients (No Agent Required)
You can use the chat client classes directly for advanced workflows:
import asyncio
from agent_framework import Message
from agent_framework.openai import OpenAIChatClient
async def main():
client = OpenAIChatClient()
messages = [
Message("system", ["You are a helpful assistant."]),
Message("user", ["Write a haiku about Agent Framework."])
]
response = await client.get_response(messages)
print(response.messages[0].text)
"""
Output:
Agents work in sync,
Framework threads through each task—
Code sparks collaboration.
"""
asyncio.run(main())
4. Build an Agent with Tools and Functions
Enhance your agent with custom tools and function calling:
import asyncio
from typing import Annotated
from random import randint
from pydantic import Field
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient
def get_weather(
location: Annotated[str, Field(description="The location to get the weather for.")],
) -> str:
"""Get the weather for a given location."""
conditions = ["sunny", "cloudy", "rainy", "stormy"]
return f"The weather in {location} is {conditions[randint(0, 3)]} with a high of {randint(10, 30)}°C."
def get_menu_specials() -> str:
"""Get today's menu specials."""
return """
Special Soup: Clam Chowder
Special Salad: Cobb Salad
Special Drink: Chai Tea
"""
async def main():
agent = Agent(
client=OpenAIChatClient(),
instructions="You are a helpful assistant that can provide weather and restaurant information.",
tools=[get_weather, get_menu_specials]
)
response = await agent.run("What's the weather in Amsterdam and what are today's specials?")
print(response)
"""
Output:
The weather in Amsterdam is sunny with a high of 22°C. Today's specials include
Clam Chowder soup, Cobb Salad, and Chai Tea as the special drink.
"""
if __name__ == "__main__":
asyncio.run(main())

5. Multi-Agent Orchestration
Coordinate multiple agents to collaborate on complex tasks using orchestration patterns:
import asyncio
from agent_framework import Agent
from agent_framework.openai import OpenAIChatClient
async def main():
# Create specialized agents
writer = Agent(
client=OpenAIChatClient(),
name="Writer",
instructions="You are a creative content writer. Generate and refine slogans based on feedback."
)
reviewer = Agent(
client=OpenAIChatClient(),
name="Reviewer",
instructions="You are a critical reviewer. Provide detailed feedback on proposed slogans."
)
# Sequential workflow: Writer creates, Reviewer provides feedback
task = "Create a slogan for a new electric SUV that is affordable and fun to drive."
# Step 1: Writer creates initial slogan
initial_result = await writer.run(task)
print(f"Writer: {initial_result}")
# Step 2: Reviewer provides feedback
feedback_request = f"Please review this slogan: {initial_result}"
feedback = await reviewer.run(feedback_request)
print(f"Reviewer: {feedback}")
# Step 3: Writer refines based on feedback
refinement_request = f"Please refine this slogan based on the feedback: {initial_result}\nFeedback: {feedback}"
final_result = await writer.run(refinement_request)
print(f"Final Slogan: {final_result}")
# Example Output:
# Writer: "Charge Forward: Affordable Adventure Awaits!"
# Reviewer: "Good energy, but 'Charge Forward' is overused in EV marketing..."
# Final Slogan: "Power Up Your Adventure: Premium Feel, Smart Price!"
if __name__ == "__main__":
asyncio.run(main())
For more advanced orchestration patterns including Sequential, Concurrent, Group Chat, Handoff, and Magentic orchestrations, see the orchestration samples.
