Land Registry Open Data MCP Server

Land Registry Open Data

HM Land Registry publishes UK House Price Index (UKHPI) data and a linked data SPARQL endpoint. No authentication required.

Data Model

• UKHPI Regions — ~350 local authority areas plus national aggregates (united-kingdom, england, wales, scotland, northern-ireland).
• Monthly Observations — Each observation has average prices (overall + by property type), house price index values, percentage changes (monthly and annual), and sales volumes.
• Property Types — Detached, semi-detached, terraced, flat/maisonette, new-build, existing property.

Region Slugs

Region identifiers are kebab-case (e.g. united-kingdom, greater-london, city-of-bristol). List UKHPI regions to discover valid slugs.

SPARQL Endpoint

The SPARQL endpoint at /landregistry/query supports the full SPARQL 1.1 specification against the Land Registry linked data store. Key prefixes:

• ukhpi: <http://landregistry.data.gov.uk/def/ukhpi/>
• lrppi: <http://landregistry.data.gov.uk/def/ppi/>
• lrcommon: <http://landregistry.data.gov.uk/def/common/>

Gotchas

• The linked data API returns results wrapped in {"format": "linked-data-api", "result": {...}}.
• Region data uses _pageSize for pagination (max 200 per page).
• SPARQL queries must be POST-ed as form-urlencoded query=... with Accept: application/json.
• Some older months may lack sales volume or seasonally adjusted fields.
