Ask your AI assistant about any UK property and get a real answer — pulled from live data, right there in the conversation.

That's Propalt AI. Connect it once and your assistant can answer for any address in the UK, straight from the official UK registers behind the API.

Connecting takes minutes. Three routes, depending on your setup — we'll walk through each: the no-code Apps route in ChatGPT, a custom connector in Claude, and a config-based setup for developer clients like Claude Code and Cursor.

What you’ll need

  • A Propalt account. The ChatGPT Apps route only needs your Propalt sign-in. The Claude custom connector and the developer-client route need an API key — subscribe to an API plan to generate one.
  • An MCP-compatible client: ChatGPT, Claude, Claude Code, or Cursor.

Connect in ChatGPT

In ChatGPT, Propalt is an official app — there’s nothing to install and no keys to paste. Signing in is all it takes.

Step 1: Open Apps and search for Propalt

In ChatGPT, click Apps in the left sidebar, type “Propalt” in the search box, and select Propalt — Property Data & Insights, UK from the results.

Step 2: Open the Propalt app page and click Connect

On the Propalt app page you’ll see a short description and a usage example. Click Connect in the top-right corner.

Step 3: Sign in to your Propalt account

Sign in with your email and password, then click Continue. This securely links your Propalt account to ChatGPT — your credentials are never shared with or stored by ChatGPT.

Step 4: Start asking property questions

You’re connected — Propalt now appears in the message box. Ask a UK property question naturally and Propalt pulls live data for ChatGPT to turn into a clear answer. For example:

  • “Give me 3 key market points an estate agent can tell a vendor in SA1”

Connect in Claude

Claude connects to Propalt through a custom connector. You add the Propalt MCP server once in Settings, then authorise it with your Propalt account.

Step 1: Open the Connectors settings

In Claude, go to Settings → Connectors → Add custom connector.

Step 3: Authorise and start asking

Sign in to your Propalt account when prompted to authorise the connection. Once authorised, Propalt’s tools are live in Claude — ask about any UK property to confirm it’s working.

Connect in a developer client

Developer clients like Claude Code and Cursor connect to Propalt over HTTP using your API key.

Step 1: Get your API key

If you don’t have one yet, subscribe to an API plan to generate your key.

Step 2: Add Propalt to your client

Add Propalt to your AI client's MCP configuration. Here are examples for popular clients:

CLAUDE CODE CLI
claude mcp add --transport http propalt-mcp https://api.propalt.io/mcp --header "Authorization: Bearer YOUR_API_KEY_HERE"
CURSOR IDE
{
  "mcp": {
    "servers": {
      "propalt-mcp": {
        "url": "https://api.propalt.io/mcp",
        "headers": { "Authorization": "Bearer YOUR_API_KEY_HERE" }
      }
    }
  }
}

Step 3: Start asking questions

Restart your client, then ask about UK property data. For example:

  • “What are property prices in Manchester?”
  • “Get rental data for SW1A 1AA”
  • “Show me planning history for 123 Baker Street”
  • “Analyze the local market yields in Liverpool L1”
