MarketCode
Data properti dan analisis untuk asisten AI di Inggris, termasuk catatan properti, penilaian, perencanaan, dan kepemilikan, melalui server MCP.
Dokumentasi
UK property data. In your AI assistant, your code, or our app.
Land Registry, Ordnance Survey, planning, energy, ownership, listings and auctions, joined at every UK address. 79 tools over it. Connect Claude or ChatGPT in a minute, or call the REST API. Most calls are free, including valuations.
One core, four products
One data layer. A product for each job.
Each product is a screen over the same tools your agent already has. One login, one bill.
The data core
Every sale since 1995, every title, every address, planning, energy, flood, council tax, company and overseas ownership, live listings and auction results. Joined at the property and kept current. On top: our valuation model and five published indices.

Claude Code
/plugin marketplace add robosapien-ai/marketcode-plugin
/plugin install marketcode@marketcode
Two commands. The plugin adds the MCP server and every skill: a short file that turns a question into a finished report, sources cited.
Any other MCP client
https://mcp.marketcode.ai/mcp
Streamable HTTP with OAuth 2.1. Steps for each client.
How it works
Connect once. Then ask, or run a skill.
01
Connect
One URL and an OAuth sign-in for Claude, ChatGPT, Codex, Cursor or Claude Code. An API key if you are writing code.
02
Ask, or run a skill
A question in plain English gets an answer. A skill gets a finished piece of work: it tells the agent which tools to call, in what order, at what cost.
03
Check the sources
Every field says where it came from and how sure we are. An estimate always comes with a range, never a bare number.
04
Scale it
REST for your code, products for your team, one credit balance across all of it.
Backed by
Built on the records everyone else quotes.

Frequently asked
Questions we get asked.
What is MarketCode?+
One UK property data core with 79 tools over it, and three ways in: your AI assistant over MCP, your code over REST, and products in the app. One account, one credit balance.
What is a skill?+
A short markdown file that tells an agent how to produce a piece of work: which calls, in what order, what they cost, how to lay out the result with every figure cited. Install the plugin in Claude Code, or paste a skill into any other client.
Do I need an API key?+
Not for an AI assistant. The MCP server signs you in with OAuth and never asks for a key. API keys are for the REST API; you create them in the Hub.
Where does the data come from?+
From the official UK records, joined at the property: HM Land Registry, Ordnance Survey, MHCLG planning data, the Environment Agency, Companies House, the EPC register, the VOA, live portal listings and auction results. On top sit our own valuation model, five published indices and the auction outcomes.
What does it cost?+
46 of 79 tools are free, including valuations. A call costs credits only where a data licence obliges it, or where you shape the query yourself. 100 free credits when you sign up; packs from £125.

The first credits are on us. The demo is thirty minutes on a property you choose.
