Longleo287 Omniclaw M365 Agents Py

Microsoft 365 Agents SDK (Python)

Build enterprise agents for Microsoft 365, Teams, and Copilot Studio using the Microsoft Agents SDK with aiohttp hosting, AgentApplication routing, streaming responses, and MSAL-based authentication.

Before implementation

• Use the microsoft-docs MCP to verify the latest API signatures for AgentApplication, start_agent_process, and authentication options.
• Confirm package versions on PyPI for the microsoft-agents-* packages you plan to use.

Important Notice - Import Changes

⚠️ Breaking Change: Recent updates have changed the Python import structure from microsoft.agents to microsoft_agents (using underscores instead of dots).

OAuth / Auto Sign-In

Copilot Studio Client (Direct to Engine)

    CopilotClient,

# Token cache (local file for interactive flows)

    # See samples for full implementation

    token_request = {"scopes": ["https://api.powerplatform.com/.default"]}
    accounts = pca.get_accounts()
    
    if accounts:
        response = pca.acquire_token_silent(token_request["scopes"], account=accounts[0])
        return response.get("access_token")
    else:
        response = pca.acquire_token_interactive(**token_request)
        return response.get("access_token")

    async for action in act:
        if action.text:
            print(action.text)
    
    # Ask question
    replies = copilot_client.ask_question("Hello!", action.conversation.id)

asyncio.run(main())

Best Practices

1. Use microsoft_agents import prefix (underscores, not dots).
2. Use MemoryStorage only for development; use BlobStorage or CosmosDB in production.
3. Always use load_configuration_from_env(environ) to load SDK configuration.
4. Include jwt_authorization_middleware in aiohttp Application middlewares.
5. Use MsalConnectionManager for MSAL-based authentication.
6. Call end_stream() in finally blocks when using streaming responses.
7. Use auth_handlers parameter on message decorators for OAuth-protected routes.
8. Keep secrets in environment variables, not in source code.
