MCP Dutch Postal Codes

🚀 MCP Dutch Postal Code Service

The MCP server is used to search for Dutch address information using Dutch postal codes or WGS84 coordinates.

🚀 Quick Start

The MCP Dutch Postal Code Service enables users to retrieve Dutch address information through postal codes or WGS84 coordinates. It can be easily configured and run in common MCP hosts or installed manually.

✨ Features

• Search for Dutch address information using postal codes.
• Support for multiple connection methods, including HTTP, SSE, and stdio.

📦 Installation

Prerequisites

• Go 1.24

Configuration Example on Common MCP Hosts (ClaudeDesktop, Cursor)

{
  "mcpServers": {
    "dutch-postal-codes": {
      "command": "go",
      "args": ["run", "github.com/dstotijn/mcp-dutch-postal-codes@main"]
    }
  }
}

Manual Installation (Assuming Go is already installed)

go install github.com/dstotijn/mcp-dutch-postal-codes@main

💻 Usage Examples

Basic Usage

$ mcp-dutch-postal-codes --help

Usage of mcp-dutch-postal-codes:
  -http string
        HTTP listen address. For JSON-RPC over HTTP (default ":8080")
  -sse
        Enable SSE connection
  -stdio
        Enable stdio connection (default true)

Advanced Usage

Generally, the MCP host runs the program to start the MCP server. However, if you want to use HTTP or SSE manually, you can run the following command:

mcp-dutch-postal-codes --stdio=false --sse

This will display the URL for the SSE connection:

2025/03/12 15:20:01 SSE Transport endpoint: http://localhost:8080
