Azure-Samples/remote-mcp-functions-dotnet

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)

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:
