HouseData MCP

An official MCP server by HouseData that enables AI assistants to access UK property data, including EPC history, flood risk, planning records, sale prices, and PRISM consent-gap scoring. It allows agents to search properties, check compliance, and retrieve detailed reports linked back to the vendor's platform.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http housedata-mcp https://housedata.uk/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add housedata-mcp --url https://housedata.uk/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable housedata-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "housedata-mcp": {
      "url": "https://housedata.uk/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "housedata-mcp": {
      "type": "streamableHttp",
      "url": "https://housedata.uk/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start housedata-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "housedata-mcp": {
      "type": "http",
      "url": "https://housedata.uk/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http housedata-mcp https://housedata.uk/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "housedata-mcp": {
      "url": "https://housedata.uk/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "housedata-mcp": {
      "serverUrl": "https://housedata.uk/mcp"
    }
  }
}
