+# What this sample demonstrates
+
+This sample demonstrates how to use a Hosted Model Context Protocol (MCP) server with an AI agent.
+The agent connects to the Microsoft Learn MCP server to search documentation and answer questions using official Microsoft content.
+
+Key features:
+- Configuring MCP tools with automatic approval (no user confirmation required)
+- Filtering available tools from an MCP server
+- Using Azure OpenAI Responses with MCP tools
+
+## Prerequisites
+
+Before running this sample, ensure you have:
+
+1. An Azure OpenAI endpoint configured
+2. A deployment of a chat model (e.g., gpt-4o-mini)
+3. Azure CLI installed and authenticated
+
+**Note**: This sample uses Azure CLI credentials for authentication. Make sure you're logged in with `az login` and have access to the Azure OpenAI resource.
+
+## Environment Variables
+
+Set the following environment variables:
+
+```powershell
+# Replace with your Azure OpenAI endpoint
+$env:AZURE_OPENAI_ENDPOINT="https://your-openai-resource.openai.azure.com/"
+
+# Optional, defaults to gpt-4o-mini
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
+```
+
+## How It Works
+
+The sample connects to the Microsoft Learn MCP server and uses its documentation search capabilities:
+
+1. The agent is configured with a HostedMcpServerTool pointing to `https://learn.microsoft.com/api/mcp`
+2. Only the `microsoft_docs_search` tool is enabled from the available MCP tools
+3. Approval mode is set to `NeverRequire`, allowing automatic tool execution
+4. When you ask questions, Azure OpenAI Responses automatically invokes the MCP tool to search documentation
+5. The agent returns answers based on the Microsoft Learn content
+
+In this configuration, the OpenAI Responses service manages tool invocation directly - the Agent Framework does not handle MCP tool calls.
