How to Set Up and Use MCP Azure Functions
MCP Azure Functions is a sample repository from Azure Samples that demonstrates how to host MCP servers built with the official Anthropic MCP Node.js SDK on Azure Functions, enabling remote cloud-hosted MCP server deployment with Microsoft Entra ID authentication. It provides both a local development workflow using Azure Functions Core Tools and a one-command cloud deployment via Azure Developer CLI (azd), complete with a weather tool example and a Microsoft Graph API On-Behalf-Of flow demo. Teams use it as a reference architecture for productionizing MCP servers in Azure with enterprise authentication baked in.
Prerequisites
- Azure subscription (free tier works for evaluation)
- Azure Developer CLI (azd) v1.17.2 or newer
- Azure Functions Core Tools v4.5.0 or newer
- Node.js 22 or newer
- Visual Studio Code with the Azure Functions extension (recommended)
Clone the repository
Download the sample to your local machine.
git clone https://github.com/Azure-Samples/mcp-sdk-functions-hosting-node.git
cd mcp-sdk-functions-hosting-node
npm installBuild the TypeScript source
Compile the TypeScript code to JavaScript before running locally.
npm run buildStart the local development server
Use Azure Functions Core Tools to start the server locally. The MCP server will be available for local testing via VS Code's .vscode/mcp.json configuration.
func startConfigure VS Code as an authorized MCP client
Set the pre-authorized client ID for VS Code so it can authenticate against your deployed Azure Function. This step uses the azd environment configuration.
azd env set PRE_AUTHORIZED_CLIENT_IDS aebc6443-996d-45c2-90f0-388ff96faa56Register the Azure resource provider
Before deploying to Azure, register the Microsoft.App resource provider in your subscription. This only needs to be done once per subscription.
az provider register --namespace 'Microsoft.App'
# Check status:
az provider show -n Microsoft.AppDeploy to Azure
Use azd up to provision all Azure resources (Azure Functions, Entra ID app registration, etc.) and deploy the MCP server in a single command. Follow the prompts to select your subscription and region.
azd upConnect VS Code to the remote MCP server
After deployment, update the .vscode/mcp.json file with the remote Azure Functions URL from the azd output. Open Copilot in Agent mode in VS Code and authenticate with your Microsoft account when prompted.
MCP Azure Functions Examples
Client configuration (local development)
VS Code MCP configuration for connecting to the locally running Azure Functions MCP server via func start.
{
"servers": {
"local-mcp-server": {
"type": "http",
"url": "http://localhost:7071/api/mcp"
}
}
}Prompts to try
Example prompts to test the weather tool and the Microsoft Graph OBO flow in VS Code Copilot Agent mode.
- "Return the weather in NYC using #local-mcp-server."
- "What is the current weather in Tokyo?"
- "Who is the currently authenticated Microsoft user?"
- "Show me the weather in London and Paris."Troubleshooting MCP Azure Functions
azd up fails with 'Microsoft.App provider not registered'
Run az provider register --namespace 'Microsoft.App' and wait for the status to show 'Registered' via az provider show -n Microsoft.App. Registration can take several minutes — do not retry azd up until the provider status is Registered.
VS Code Copilot cannot connect to the local server
Ensure the .vscode/mcp.json file is in the project root (not a subdirectory) and that func start is running. Also confirm the port in host.json matches the port in your mcp.json URL — the default Azure Functions port is 7071.
Authentication fails when connecting to the remote Azure Function
Make sure PRE_AUTHORIZED_CLIENT_IDS is set to the correct VS Code client ID (aebc6443-996d-45c2-90f0-388ff96faa56) before deploying. If you already deployed without it, set the env variable and re-run azd up to update the deployment.
