MCP server for querying Dutch postal codes

0 stars GoServers & Infrastructure Updated Jul 10, 2025

Documentation

mcp-dutch-postal-codes

MCP server for retrieving Dutch address information by postal code or WGS84

coordinates.

This server is built using the official MCP Go SDK.

Requirements

Go 1.24

Installation

Configuration for common MCP hosts (Claude Desktop, Cursor):

json

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

Alternatively, you can manually install the program (given you have Go installed):

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

Usage

code

$ 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 transport
  -stdio
        Enable stdio transport (default true)

Typically, your MCP host will run the program and start the MCP server, and you

don't need to manually do this. But if you want to run the MCP server manually,

for instance because you want to serve over HTTP (using SSE):

Given you have your `PATH` environment configured to include the path named by

`$GOBIN` (or `$GOPATH/bin` `$HOME/go/bin` if `$GOBIN` is not set), you can then

run:

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

Which will output the SSE transport URL:

code

2025/03/12 15:20:01 MCP server started, using transports: [sse]
2025/03/12 15:20:01 SSE transport endpoint: http://localhost:8080
