* PR1: Add core context provider types and tests New types in _sessions.py (no changes to existing code): - SessionContext: per-invocation state with extend_messages/get_messages/ extend_instructions/extend_tools and read-only response property - _ContextProviderBase: base class with before_run/after_run hooks - _HistoryProviderBase: storage base with load/store flags, abstract get_messages/save_messages, default before_run/after_run - AgentSession: lightweight session with state dict, to_dict/from_dict - InMemoryHistoryProvider: built-in provider storing in session.state 35 unit tests covering all classes and configuration flags. * feat: keyword-only params, stateless InMemoryHistoryProvider, deep serialization - Make before_run/after_run parameters keyword-only - InMemoryHistoryProvider stores ChatMessage objects directly (no per-cycle serialization) - Deep serialization via to_dict/from_dict only at session boundary - State type registry for automatic deserialization of registered types - Updated tests for new serialization approach * feat: add new-pattern provider implementations for external packages - _RedisContextProvider(BaseContextProvider) - Redis search/vector context - _RedisHistoryProvider(BaseHistoryProvider) - Redis-backed message storage - _Mem0ContextProvider(BaseContextProvider) - Mem0 semantic memory - _AzureAISearchContextProvider(BaseContextProvider) - Azure AI Search (semantic + agentic) All use temporary _ prefix names for side-by-side coexistence with existing providers. Will be renamed in PR2 when old ContextProvider/ChatMessageStore are removed. * test: add tests for new-pattern provider implementations - 32 tests for _RedisContextProvider and _RedisHistoryProvider - 29 tests for _Mem0ContextProvider - 17 tests for _AzureAISearchContextProvider * fix: address PR review comments and CI failures - Move module docstring before imports in _sessions.py (review comment) - Import TYPE_CHECKING unconditionally in Redis _context_provider.py (NameError on Python <3.12) - Fix Mem0 test_init_auto_creates_client_when_none to patch at class level * feat: add source attribution to extend_messages Set attribution marker in additional_properties for each message added via extend_messages(), matching the tool attribution pattern. Uses setdefault to preserve any existing attribution. * refactor: make attribution value a dict with source_id key * add attribution and use sets for filters * Add source_type to message attribution and copy messages in extend_messages - SessionContext.extend_messages now accepts source as str or object with source_id attribute; when an object is passed, its class name is recorded as source_type in the attribution dict - Messages are shallow-copied before attribution is added so callers' original objects are never mutated - Filter framework-internal keys (attribution) from A2A wire metadata to prevent leaking internal state over the wire * fix: correct mypy type: ignore comment from union-attr to attr-defined * set attribution to _attribution * adjusted naming of bools
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
chat_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 ChatAgent
from agent_framework.openai import OpenAIChatClient
async def main():
agent = ChatAgent(
chat_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 ChatMessage
from agent_framework.openai import OpenAIChatClient
async def main():
client = OpenAIChatClient()
messages = [
ChatMessage("system", ["You are a helpful assistant."]),
ChatMessage("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 ChatAgent
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 = ChatAgent(
chat_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 ChatAgent
from agent_framework.openai import OpenAIChatClient
async def main():
# Create specialized agents
writer = ChatAgent(
chat_client=OpenAIChatClient(),
name="Writer",
instructions="You are a creative content writer. Generate and refine slogans based on feedback."
)
reviewer = ChatAgent(
chat_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())
