How to Set Up and Use Remote MCP Functions .NET
Remote MCP Functions .NET is a quickstart template from Microsoft Azure Samples that shows how to build and deploy a custom remote MCP server using Azure Functions and C#. It includes five ready-to-run sample servers covering MCP Tools (snippet CRUD, QR code generation, badges), MCP Apps (interactive UI via fluent API), MCP Resources, MCP Prompts, and a Weather App demo. With `azd up`, you can go from a local clone to a cloud-hosted, Entra-authenticated MCP server in minutes.
Prerequisites
- .NET 10 SDK installed
- Azure Functions Core Tools v4.5.0 or higher
- Azure Developer CLI (azd) v1.23.x or above
- Docker (for the Azurite local storage emulator used during local development)
- An Azure subscription with permissions to create Function Apps and Entra app registrations
Clone the repository
Clone the Azure Samples repository to your local machine.
git clone https://github.com/Azure-Samples/remote-mcp-functions-dotnet.git && cd remote-mcp-functions-dotnetExplore the sample MCP servers
The repository contains five sample projects: FunctionsMcpTool, FunctionsMcpApp, FunctionsMcpResources, FunctionsMcpPrompts, and McpWeatherApp. Each project folder has its own README with specifics.
ls -laRun locally with Azure Functions Core Tools
Start a sample server locally. Azurite (via Docker) provides the local storage emulator. Navigate into the desired sample project directory first.
cd FunctionsMcpTool && func startDeploy to Azure with azd up
Deploy the sample to your Azure subscription. `azd up` provisions the Function App, sets up Entra authentication, and deploys the code in one command.
azd upConnect your MCP client to the remote endpoint
After deployment, azd outputs the Function App URL. Configure your MCP client to connect to it over HTTP with Entra bearer token authentication.

}Capabilities and example prompts
The FunctionsMcpTool sample exposes snippet management, QR code generation, and badge creation. The McpWeatherApp exposes interactive weather UI.
- "Save this code snippet with the title 'hello-world' and tag it as 'example'."
- "Generate a QR code for the URL https://example.com."
- "Create a shield badge showing version 1.0.0 in green."
- "What's the current weather in Seattle?" (McpWeatherApp)
- "List all my saved code snippets tagged as 'python'."Troubleshooting Remote MCP Functions .NET
func start fails with 'Azurite is not running' or storage connection errors
Start the Azurite storage emulator with `docker run -p 10000:10000 -p 10001:10001 -p 10002:10002 mcr.microsoft.com/azure-storage/azurite` before running `func start`, or install Azurite globally via `npm install -g azurite`.
azd up fails with authentication or permission errors
Run `azd auth login` to authenticate with your Azure account before running `azd up`. Ensure your account has Contributor rights on the target subscription and permission to create Entra app registrations.
MCP client gets 401 Unauthorized when connecting to the deployed Function App
The deployed server uses Microsoft Entra (AAD) authentication. Your MCP client must include a valid bearer token in the Authorization header. Consult the sample project's README for the correct Entra app registration scope and token acquisition flow.
