Dstotijn MCP Dutch Postal Codes Server

Provides Dutch address lookups by postal code or coordinates via MCP, enabling fast, reliable address data retrieval.

Installation

Add the following to your MCP client configuration file.

Configuration

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

This MCP server provides fast access to Dutch address information by postal code or coordinates in the WGS84 system. It lets you look up addresses efficiently from your MCP-enabled client, enabling seamless integration for location-aware workflows.

How to use

You connect to this MCP server from your MCP client and request address data by postal code or geographic coordinates. The server supports JSON-RPC over HTTP and a streaming transport, so you can choose the transport that best fits your application's needs. Use the server to enrich forms, validate addresses in bulk, or build location-based features that rely on accurate Dutch address data.

How to install

Prerequisites you need before installing this MCP server are Go 1.24 or newer and a configured Go toolchain on your development or runtime host.

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

Optionally, you can install the program directly with Go if you prefer a single binary in your Go bin directory.

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

To run manually with standard input/output (stdio) and enable streaming (SSE) transports, you can execute the binary via Go tooling after ensuring your PATH includes the Go bin directory.

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

When started with these settings, the server will expose an SSE transport URL that you can connect to from your MCP client, for example http://localhost:8080 if using default ports.

Additional notes

The server is built with the official MCP Go SDK and ships with a minimal runtime configuration example showing how to register the server under your MCP host. If you need to run in a different transport mode, adjust the flags accordingly and refer to your MCP host’s transport configuration for guidance.
