Local Development

bash

npm install
npm run dev     # hot-reload with tsx

Test the server:

bash

# Health check
curl http://localhost:3000/health

# Initialize MCP session
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}'

Build

bash

npm run build   # TypeScript → dist/
npm start       # run production build

Deploy to Azure

Prerequisites

Azure CLI installed
Azure Developer CLI (azd) installed
An Azure subscription

Deploy

bash

# Login to Azure
azd auth login

# Initialize environment (first time only)
azd init

# Provision infrastructure + deploy app
azd up

This will:

Create a Resource Group
Create an Azure Container Registry
Build and push the Docker image
Create a Container Apps Environment with Log Analytics
Deploy the Container App with auto-scaling (1–5 replicas)

Subsequent deploys

bash

azd deploy       # redeploy code only (no infra changes)

Environment outputs

After deployment, azd will display:

SERVICE_MCP_URI — The public HTTPS URL of your MCP server

Your MCP endpoint will be at: https://<your-app>.azurecontainerapps.io/mcp

Architecture

Client → HTTPS → Azure Container Apps (auto-scaled)
                    ├── /health  (GET — health check)
                    └── /mcp     (POST/GET/DELETE — MCP protocol)
                          ↕
                  Streamable HTTP Transport
                          ↕
                  MCP Server (tools, resources, prompts)

Infrastructure

Resource	Purpose
Container Registry	Hosts Docker images
Container Apps Environment	Managed Kubernetes with Log Analytics
Container App	Runs the MCP server (0.5 vCPU, 1 GiB RAM)

Adding Your Own Tools

Edit src/tools.ts to register custom tools:

typescript

server.tool(
  "my_tool",
  "Description of what this tool does",
  { param: z.string().describe("Parameter description") },
  async ({ param }) => ({
    content: [{ type: "text", text: `Result: ${param}` }],
  })
);

Rebuild and redeploy:

bash

npm run build && azd deploy
