MCP Server Azure Function

🚀 Azure Functions ⚡️❤️ MCP Server

This repository is part of a video on my YouTube channel, which demonstrates how to create an MCP (Model Context Protocol) server using Azure Functions and integrate it with the proxy mode of GitHub Copilot Chat.

🚀 Quick Start

✨ Features

This project allows you to create an MCP server using Azure Functions and interact with it through GitHub Copilot Chat.

📦 Installation

To create an MCP server using Azure Functions, you can use the following library:

dotnet add package Microsoft.Azure.Functions.Worker.Extensions.Mcp --version 1.0.0-preview.2

For more details about this NuGet package, please visit: https://www.nuget.org/packages/Microsoft.Azure.Functions.Worker.Extensions.Mcp

💻 Usage Examples

Basic Usage

To test the example code, you need to run the project locally:

func start

You can use the MCP inspector:

npx @modelcontextprotocol/inspector http://localhost:7071/runtime/webhooks/mcp/sse

You can also interact with this MCP server using GitHub Copilot Chat. To do this, simply create a .vscode/mcp.json file or include the following section in your .vscode/settings.json:

{
    "inputs": [
        {
            "type": "promptString",
            "id": "mcp-azure-function-key",
            "description": "Key to access the Azure function",
            "password": true
        },
        {
            "type": "promptString",
            "id": "mcp-azure-function-name",
            "description": "Name to access the Azure function"
        }
    ],
    "servers": {
        "local-mcp-azure-function": {
            "type": "sse",
            "url": "http://localhost:7071/runtime/webhooks/mcp/sse",
        },
        // "remote-mcp-azure-function": {
        //     "type": "sse",
        //     "url": "https://${input:mcp-azure-function-name}.azurewebsites.net/runtime/webhooks/mcp/sse",
        //     "headers": {
        //         "x-functions-key": "${input:mcp-azure-function-key}"
        //     }
        // }
    }
}

You can also add an MCP via the command line:

code --add-mcp '{"name": "local-mcp", "type": "sse", "url": "http://localhost:7071/runtime/webhooks/mcp/sse"}'

Advanced Usage

If you are using Terraform to deploy Azure resources, make sure to include the following in your outputs.tf file:

output "function_name" {
  value = azure_function.name
}

output "function_master_key" {
  value = azure_function.master_key
}

After deployment, you can find the function name and master key in the Terraform output.

📚 Documentation

Install the NuGet Package

Install the following NuGet package in your project:

dotnet add package Microsoft.Azure.Functions.Worker.Extensions.Mcp --version 1.0.0-preview.2

Run the Project

Start your Azure Functions project:

func start

When prompted for the function name and master key, provide the corresponding information you found in the Azure portal.

Test the MCP Server

Use the following command to test if the MCP server is running correctly:

npx @modelcontextprotocol/inspector http://localhost:7071/runtime/webhooks/mcp/sse

Configure GitHub Copilot Chat

To configure the MCP server in GitHub Copilot Chat, follow these steps:

1. Create or edit the .vscode/settings.json file in your project root directory.
2. Add the following content to configure the MCP server:

{
    "inputs": [
        {
            "type": "promptString",
            "id": "mcp-azure-function-key",
            "description": "Key to access the Azure function",
            "password": true
        },
        {
            "type": "promptString",
            "id": "mcp-azure-function-name",
            "description": "Name to access the Azure function"
        }
    ],
    "servers": {
        "local-mcp-azure-function": {
            "type": "sse",
            "url": "http://localhost:7071/runtime/webhooks/mcp/sse",
        },
        // "remote-mcp-azure-function": {
        //     "type": "sse",
        //     "url": "https://${input:mcp-azure-function-name}.azurewebsites.net/runtime/webhooks/mcp/sse",
        //     "headers": {
        //         "x-functions-key": "${input:mcp-azure-function-key}"
        //     }
        // }
    }
}
