MCP Server Documentation

MCP Server

Connect AI assistants like Claude, Cursor, or any MCP-compatible client to Deed Insight for natural language access to UK property & land data. Just point your client at https://deedinsight.co.uk/mcp — no install, no API key required.

What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants connect to external data sources. With Deed Insight's MCP server, you can ask your AI assistant questions like:

"What's the recent sale history for OX1 5BW?"
"List every property owned by Companies House number 07465254."
"Who are the proprietors of title CYM566831?"
"Show me the most expensive UK property sales ever recorded."

Connect

Our remote server speaks the MCP Streamable HTTP transport at:

https://deedinsight.co.uk/mcp

It's public and read-only — no API key, no install. Pick your client:

Claude Code (CLI)

claude mcp add --transport http deed-insight https://deedinsight.co.uk/mcp

Claude.ai / Claude Desktop

Go to Settings → Connectors → Add custom connector, give it a name (e.g. "Deed Insight") and paste the URL above.

Cursor / Windsurf / other URL-aware clients

Add to your MCP config (e.g. ~/.cursor/mcp.json):

{
  "mcpServers": {
    "deed-insight": {
      "url": "https://deedinsight.co.uk/mcp"
    }
  }
}

Stdio-only clients (bridge)

If your client only supports stdio, bridge to the hosted server with mcp-remote:

{
  "mcpServers": {
    "deed-insight": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://deedinsight.co.uk/mcp"]
    }
  }
}
