What it does

Point any MCP-capable client (Claude Desktop, Cursor, n8n, Make, Zapier, custom agents) at this server and get fast, structured answers to Hungarian address questions:

Validate a (postcode, city) pair before storing it in your DB
Look up the settlement and county for any HU postcode
Find all postcodes that serve a given city (handy for Budapest: 23 districts, 100+ postcodes)
List every postcode in a Hungarian county
Map Budapest district numbers (1–23 or I–XXIII) to their postcode ranges

Tools

Tool	Purpose	Price
`lookup_postcode(postcode)`	Settlement + county + (if BP) district for a 4-digit HU postcode	$0.001
`lookup_city(city)`	All postcodes for a city (diacritic-insensitive — `gyor` matches `Győr`)	$0.001
`validate_address(postcode, city)`	yes/no + corrected suggestion if mismatch	$0.001
`budapest_district_lookup(district)`	Budapest I-XXIII (or 1-23) → list of postcodes in that district	$0.001
`list_postcodes_in_county(county_name)`	Bulk listing — every postcode in a county	$0.005

Example responses

lookup_postcode(1102)

config.json

{
  "postcode": 1102,
  "found": true,
  "matches": [
    {
      "postcode": 1102,
      "settlement": "Budapest",
      "settlement_part": "X. kerület",
      "county": "Budapest"
    }
  ],
  "budapest_district": "X."
}

validate_address(1102, "Szeged")

config.json

{
  "valid": false,
  "reason": "city_mismatch",
  "postcode": 1102,
  "city": "Szeged",
  "expected_settlements": ["Budapest"]
}

budapest_district_lookup(14) (or "XIV") returns all postcodes in District XIV.

Pricing

Event	USD per call
`lookup-call` (most tools)	$0.001
`bulk-call` (`list_postcodes_in_county`)	$0.005

Effectively a free utility for occasional use; meaningful at high call volumes.

Data sources

Magyar Posta official postal catalog (Iranyitoszam-Internet_uj.xlsx) — postcode → settlement mapping
KSH (Hungarian Central Statistical Office) settlement registry — county / district / KSH code per settlement, via the open tamas-ferenci/IrszHnk compilation

Coverage: 3,484 postcode-settlement entries spanning 2,962 unique postcodes (1011–9985), all 19 Hungarian counties + Budapest. Refreshed quarterly.
