Rabobank Server Training

Welcome to the Rabobank MCP-Server Training repository. This project contains a fully functional demo Model Context Protocol (MCP) server built with TypeScript that you can use as a starting point during the training.

---

What is MCP?

The Model Context Protocol is an open standard that allows AI assistants (like GitHub Copilot and Claude) to call external tools and data sources in a structured, secure way. An MCP server exposes tools, resources, and prompts that any MCP-compatible client can discover and invoke.

Demo tools included

Tool	Description
get_exchange_rate	Returns a (mocked) EUR exchange rate for a given currency code
calculate_mortgage	Calculates the monthly mortgage payment given principal, annual rate and term
get_branch_info	Returns contact details for a mock Rabobank branch

Prerequisites

• Node.js v18 or higher
• npm (comes with Node.js)

---

Quick start

# 1. Clone the repository
git clone https://github.com/RemseyMailjard/rabobank-mcp-server-training.git
cd rabobank-mcp-server-training

# 2. Install dependencies
npm install

# 3. Build
npm run build

# 4. Run (stdio)
node build/index.js

Use with VS Code (GitHub Copilot)

The .vscode/mcp.json file is already configured. Open the project in VS Code and Copilot will automatically discover the server.

Use with Claude for Desktop

Add the following entry to your claude_desktop_config.json:

{
  "mcpServers": {
    "rabobank-demo": {
      "command": "node",
      "args": ["C:\\path\\to\\rabobank-mcp-server-training\\build\\index.js"]
    }
  }
}

Exercises

During the training you will:

1. Explore the existing tools in src/index.ts and understand how they are registered.
2. Add a new tool – e.g. get_interest_rate that returns savings account interest rates.
3. Add a resource – expose a static JSON file with product information.
4. Add a prompt – create a reusable prompt template for a customer service scenario.
5. Connect the server to GitHub Copilot Chat or Claude for Desktop and test the tools interactively.
