- Supports securing via API Management and network isolation with VNET
- Interactive UI capabilities through MCP Apps and the Weather App demo
- One‑command cloud deployment using Azure Developer CLI (azd up)
Clone the repository, restore dependencies, and run the samples locally with debugging using Visual Studio or Visual Studio Code. Once ready, run azd up to deploy the entire server infrastructure to Azure in a few minutes. Prerequisites include .NET 10 SDK, Azure Functions Core Tools >=4.5.0, Azure Developer CLI >=1.23.x, and Docker.
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.
If you're looking for samples in more languages check out the Node.js/TypeScript and Python samples.
Prerequisites
Required for all development approaches
+ .NET 10 SDK
+ Azure Functions Core Tools >= 4.5.0
+ Azure Developer CLI 1.23.x or above (for deployment)
+ Docker (for the Azurite storage emulator)
For Visual Studio development
+ Visual Studio 2022
+ Make sure to select the Azure development workload during installation
For Visual Studio Code development
+ Visual Studio Code
+ Azure Functions extension
> 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:
