Stop both terminals with `Ctrl+C` when done. --- ## Deploy to Azure (remote MCP) Want the function app inside a VNet *before* provisioning? Just set: ```bash azd env set VNET_ENABLED true ``` Then provision + deploy in one step: ```bash azd up ``` --- ## Connect clients to the *remote* MCP server The hosted SSE endpoint will be: ``` https://.azurewebsites.net/runtime/webhooks/mcp/sse ``` > **Key required** > Grab the **system key** named `mcp_extension` from the Azure Portal > or via CLI: > `az functionapp keys list --resource-group --name ` ### MCP Inspector ``` https://.azurewebsites.net/runtime/webhooks/mcp/sse?code= ``` ### VS Code – GitHub Copilot Add a header in `mcp.json`: ```jsonc { "servers": { "remote-mcp-function": { "type": "sse", "url": "https://.azurewebsites.net/runtime/webhooks/mcp/sse", "headers": { "x-functions-key": "" } }, "local-mcp-function": { "type": "sse", "url": "http://127.0.0.1:7071/runtime/webhooks/mcp/sse" } } } ``` Start **remote-mcp-function** and chat as usual in Copilot. --- ## Redeploy code ```bash azd up # Safe to run repeatedly—always overwrites the app with the latest build ``` ## Clean up ```bash azd down ``` --- ## Source Code Layout | Tool | Path | Description | | ------------------------------ | -------------------------------------------------------------------------------------------- | ------------------------------------------- | | **HelloWorld** | [`src/main/java/com/function/HelloWorld.java`](./src/main/java/com/function/HelloWorld.java) | Logs an argument then prints “Hello World”. | | **SaveSnippets / GetSnippets** | [`src/main/java/com/function/Snippets.java`](./src/main/java/com/function/Snippets.java) | Saves / retrieves snippets to Blob Storage. | --- ## How It Works

### MCP Tool Trigger ```java @McpToolTrigger( toolName = "saveSnippets", description = "Saves a text snippet to your snippets collection.", toolProperties = SAVE_SNIPPET_ARGUMENTS // JSON schema string ) ``` * `toolProperties` defines the JSON payload expected from the client. * At runtime the JSON is passed to your function in `toolArguments`. ### Storage Bindings ```java @BlobOutput( name = "snippetOut", path = "snippets/{mcptoolargs.snippetName}.json", dataType = "binary") ``` * `SaveSnippets` writes to a blob; `GetSnippets` reads the same path. * The default storage account is referenced with `@StorageAccount("AzureWebJobsStorage")`. ### Required SDK + Extension Bundle ```xml 3.1.1-alpha ``` ```jsonc // host.json { "extensionBundle": { "id": "Microsoft.Azure.Functions.ExtensionBundle.Experimental", "version": "[4.*, 5.0.0)" } } ```

--- ## Next Steps * Front your MCP server with **API Management** for fine-grained policies. * Add **EasyAuth** to use your favourite OAuth provider (including Entra ID). * Toggle VNet integration via `VNET_ENABLED=true` for network isolation. * Explore the [Model Context Protocol](https://github.com/modelcontextprotocol) ecosystem for more tools.2a:T5cf,## What is Remote MCP Functions (Java)? Remote MCP Functions (Java) is a quickstart template designed to build and deploy a custom remote Model Context Protocol (MCP) server using Azure Functions with Java. It allows developers to run a secure and scalable server in the cloud. ## How to use Remote MCP Functions (Java)? To use this project, set up your local envir
