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

mcp-dutch-postal-codes

MCP server for retrieving Dutch address information by postcal code or WGS84 coordinates.

Requirements

Installation

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

{
  "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

$ 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:

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