Demo MCP Server (.NET 10)

Builds on section 02 by adding todo list tools (AddTodo, GetTodoList, DeleteTodo) backed by Azure Table Storage. No authentication. Introduces Azure Storage setup used in later sections.

Before you run

1. Azure Storage Connection String: Replace <AZURE_STORAGE_CONNECTION_STRING> in:

   • src/McpServerTodoList/appsettings.json
   • .vscode/launch.json (env section, for F5 debugging)

   Get the value from Azure Portal → Storage Account → Access keys.

MCP Server - Azure Table Storage Setup (Cheapest & Simplest)

This guide explains how to set up Azure Table Storage and connect it to a .NET MCP Server using a storage account connection string.

This approach is deliberately:

• ✅ Low cost
• ✅ Low ceremony
• ✅ Easy to understand
• ❌ Not production-grade security (by design, for teaching)

---

Overview

We will:

1. Create a low-cost Azure Storage Account
2. Enable Table Storage
3. Copy the connection string
4. Store it in appsettings.json
5. Use it from C# to read/write todos

---

1. Create the Azure Storage Account

In the Azure Portal:

1. Create resource → Storage account
2. Use the following settings:

Basics

• Resource group: your existing MCP server resource group
• Storage account name: any globally unique name (e.g. jcmpserverdemo01)
• Region: same as your Container App
• Performance: Standard
• Replication: Locally-redundant storage (LRS)
• Preferred storage type:
  👉 Other (tables and queues)

This is the cheapest possible configuration that supports Azure Table Storage.

---

2. Security & Networking (keep it simple)

You can leave most settings as default.

Important points:

• Public network access: Enabled
• Secure transfer required: Enabled
• Storage account key access: Enabled

We intentionally allow key-based access to avoid managed identity and RBAC complexity in this demo.

3. Create the Table

After the storage account is created:

1. Go to Storage account → Storage browser
2. Open Tables
3. Click Add table
4. Name it: Todos
