Azure MCP Server Is Now a .mcpb — Install It Without Any Runtime

The Azure MCP Server is now available as an MCP Bundle (.mcpb) — download it, drag it into Claude Desktop, and you're done. No Node.js, Python, or .NET runtime required.

You know what was annoying about setting up MCP servers? You needed a runtime. Node.js for the npm version, Python for pip/uvx, .NET SDK for the dotnet flavor, Docker if you wanted containers. Just to get a tool connected to your AI client.

The Azure MCP Server just changed that. It’s now available as an .mcpb — an MCP Bundle — and the setup is drag-and-drop.

What’s an MCP Bundle?

Think of it like a VS Code extension (.vsix) or a browser extension (.crx), but for MCP servers. A .mcpb file is a self-contained ZIP archive that includes the server binary and all its dependencies. Everything needed to run on your platform, packaged together.

The end result: you download one file, open it in a supported client, and the server runs. No runtime to install, no package.json to manage, no version conflicts.

How to install it

Three steps:

1. Download the bundle for your platform

Go to the GitHub Releases page and grab the .mcpb file for your OS and architecture. Make sure you pick the right one — osx-arm64 for Apple Silicon, osx-x64 for Intel Mac, etc.

2. Install in Claude Desktop

The easiest way: drag and drop the .mcpb file into the Claude Desktop window while you’re on the Extensions settings page (☰ → File → Settings → Extensions). Review the server details, click Install, confirm. Done.

Tip: You can also set Claude Desktop as the default app for .mcpb files and double-click to install.

3. Authenticate to Azure

That’s it. The Azure MCP Server uses your existing Azure credentials.

What you can do with it

Once installed, you have access to 100+ Azure service tools directly from your AI client:

  • Query and manage Cosmos DB, Storage, Key Vault, App Service, Foundry
  • Generate az CLI commands for any task
  • Create Bicep and Terraform templates
  • Get architecture recommendations and diagnostics

Try prompts like:

  • “List all resource groups in my subscription”
  • “Generate a Bicep template for a web app with a SQL database”
  • “What Cosmos DB databases do I have?”
  • “Show me the secrets in my Key Vault named my-vault”

Which install method should you use?

MethodBest for
.mcpbClaude Desktop users who want zero-config
VS Code ExtensionDevelopers working in VS Code + GitHub Copilot
npm/npxDevelopers who already have Node.js
pip/uvxPython developers
DockerCI/CD pipelines and containers

All methods give you the same tools. The .mcpb is just the most frictionless path for Claude Desktop users.

Why this matters

MCP servers are genuinely useful — they let AI clients interact with external systems in a structured way. But the setup friction has been a real barrier, especially for users who aren’t developers or who just don’t want to manage runtimes for every tool they install.

The .mcpb format feels like the right direction. It’s the same principle as VS Code extensions or browser extensions: one file, platform-native binary, install and go.

If the MCP ecosystem keeps moving this direction, connecting AI clients to services will get a lot simpler.
