If you're experimenting with the Model Context Protocol (MCP), you've already seen how powerful it is for connecting tools, agents, and applications into unified workflows.
But the real magic happens when your MCP server is not running on your laptop… but deployed in the cloud.
Azure now provides first-class support for Remote MCP Servers built in TypeScript and JavaScript, giving you scalable, secure, team-ready capabilities for AI-integrated workflows—from GitHub Copilot to custom agent frameworks.
This post covers why Remote MCP Servers matter, how Azure Functions make them simple, and where to start with official docs and sample repos.
🌩️ Why Build a Remote MCP Server?
Local MCP servers are great for quick prototyping, but teams hit real limits:
- Local servers can’t scale
- They aren’t shareable
- They break inside containers and DevBoxes
- They can’t reach VNet-secured resources
- They rely on local credentials
- Long-running tasks are fragile
Remote MCP Servers on Azure solve all of this.
Running in Azure Functions gives you:
- Serverless scale
- Enterprise-grade security
- Managed Identity (no secrets on laptops)
- Team-wide reusability
- Integration with Azure services (Key Vault, SQL, Cosmos, Storage, Container Apps, etc.)
If you're building anything “agentic,” this unlocks a new world of capabilities.
📘 Start With the Official Microsoft Docs
Azure has three key resources to help you get started:
👉 Full Tutorial (TypeScript)
Build a Remote MCP server on Azure Functions
https://learn.microsoft.com/en-us/azure/azure-functions/functions-mcp-tutorial?tabs=mcp-extension&pivots=programming-language-typescript
This covers:
- Setting up your project
- Writing your first MCP action
- Deploying with
azd - Securing access
- Testing from VS Code
👉 Quickstart: Custom Remote MCP Server
Perfect if you already understand Functions and want the shortest path to success.
👉 Official Sample Repo
https://github.com/Azure-Samples/remote-mcp-functions
Includes:
- Multiple MCP endpoints
- Schemas & patterns
- Deployment templates (
azd) - Logging + error-handling examples
- A recommended project structure
Use this repo as your starting point when building your own server.
🛠 How It Works (Simplified)
A Remote MCP server is just an Azure Function that returns MCP-compliant JSON.
Here’s a minimal TypeScript example:
// Hello function - responds with hello message
export async function mcpToolHello(_toolArguments:unknown, context: InvocationContext): Promise<string> {
console.log(_toolArguments);
// Get name from the tool arguments
const mcptoolargs = context.triggerMetadata.mcptoolargs as {
name?: string;
};
const name = mcptoolargs?.name;
console.info(`Hello ${name}, I am MCP Tool!`);
return `Hello ${name || 'World'}, I am MCP Tool!`;
}
// Register the hello tool
app.mcpTool('hello', {
toolName: 'hello',
description: 'Simple hello world MCP Tool that responses with a hello message.',
toolProperties:{
name: arg.string().describe('Required property to identify the caller.').optional()
},
handler: mcpToolHello
});
Deploy to Azure:
azd up
Now your MCP server is reachable from:
- VS Code MCP Extension
- GitHub Copilot
- LangChain agents
- Custom MCP clients
- Automation pipelines and CI/CD
💡 What Developers Are Building Today
🔹 Cloud & infra automation
Validate Bicep, deploy Container Apps, check resource health.
🔹 DevOps workflows
Run tests, inspect containers, automate PR tasks.
🔹 Secure enterprise data connectors
Provide scoped, read-only access to internal SQL, Storage, Key Vault, etc.
🔹 Knowledge tools
Chunk, embed, and search documents stored in Azure.
🔹 Multi-step orchestration
Expose “one-call” MCP actions that run entire workflows under the hood.
🌐 Why TypeScript + Azure Functions Is a Perfect Match
- Type-safe MCP schemas
- Serverless autoscale
- Zero infrastructure
- Managed Identity → no secrets in your MCP client
-
One-command deploy (
azd up) - Great for local dev, Codespaces, or remote teams
If you're already writing Node/TS, this feels natural and productive.
🧪 Try It Yourself — And Give Feedback
This is an evolving area—and Microsoft is actively looking for real developer feedback.
If you're building:
- custom AI tools
- cloud automation
- team-wide secure connectors
- multi-tool agent solutions
Now is the perfect time to explore Remote MCP Servers and help shape the next wave of agentic development.
🙌 Wrap-Up
Remote MCP Servers on Azure give developers cloud-grade scale, identity, and reliability, and TypeScript support makes them incredibly easy to adopt.
