MCP.Pizza Chef: Azure-Samples

remote-mcp-functions-dotnet is a quickstart template for building and deploying a secure remote MCP server using Azure Functions and .NET/C#. It enables local development with debugging and easy cloud deployment via Azure Developer CLI. The server supports security features like keys, HTTPS, OAuth integration, API Management, and network isolation with VNET, making it ideal for scalable, secure MCP server hosting in the cloud.

README

Getting Started with Remote MCP Servers using Azure Functions (.NET/C#)

This repo has a collection of samples to help you easily build and deploy a custom remote MCP server to the cloud using Azure functions. You can clone/restore/run on your local machine with debugging, and azd up to have a server in the cloud in a couple minutes.

All sample MCP servers are configured with built-in authentication using Microsoft Entra as the identity provider.

You can also use API Management to secure the server, as well as network isolation using VNET.

Prerequisites

Required for all development approaches

For Visual Studio development

  • Visual Studio 2022
  • Make sure to select the Azure development workload during installation

For Visual Studio Code development

Choose one: You can use either Visual Studio OR Visual Studio Code. Both provide full debugging support, but the setup steps differ slightly.

Below is the architecture diagram for the Remote MCP Server using Azure Functions:
