# Agent Framework Foundry This package contains the Microsoft Foundry integrations for Microsoft Agent Framework, including Foundry chat clients, preconfigured Foundry agents, Foundry embedding clients, and Foundry memory providers. ## Toolboxes A *toolbox* is a named, versioned bundle of hosted tool configurations — code interpreter, file search, image generation, MCP, web search, and so on — stored inside a Microsoft Foundry project. Toolboxes let you manage tool configuration once and reuse it across agents. ### Authoring a toolbox Toolboxes can be authored two ways: - **Foundry portal** — create and version toolboxes through the UI without touching code. - **Programmatically** — use the [`azure-ai-projects`](https://pypi.org/project/azure-ai-projects/) SDK to create, update, and version toolboxes from Python. > Toolbox authoring APIs (`ToolboxVersionObject`, `ToolboxObject`, `project_client.beta.toolboxes.*`) require `azure-ai-projects>=2.1.0`. Earlier versions can only consume toolboxes that already exist. ### Using toolboxes with `FoundryAgent` For hosted `FoundryAgent`, the toolbox must already be attached to the agent in the Microsoft Foundry project. Once attached, the agent invokes its toolbox tools transparently — no client-side wiring required — and you interact with the agent the same way you would with any other tool-equipped Foundry agent. ### Using toolboxes with `FoundryChatClient` Each toolbox is reachable as an MCP server. Connect to the toolbox's MCP endpoint with `MCPStreamableHTTPTool` — the agent then discovers and calls its tools over MCP at runtime: ```python from agent_framework import Agent, MCPStreamableHTTPTool from agent_framework.foundry import FoundryChatClient async with Agent( client=FoundryChatClient(...), instructions="You are a helpful assistant. Use the toolbox tools when useful.", tools=MCPStreamableHTTPTool( name="my_toolbox", description="Tools served by my Foundry toolbox", url="https://", ), ) as agent: result = await agent.run("What tools are available?") print(result.text) ```
