Model Context Protocol

Connect your AI to live UK mortgage rates.

Add our MCP server to ChatGPT, Claude or Cursor and your assistant can search, compare and price real mortgage products on demand — the same data that powers this site.

● LIVE · TIER-0https://api.mortgagesourcing.com/mcpCopy this URL into your client

Add it in 3 steps

Up and running in under a minute.

Copy the endpoint

Grab the MCP URL above. It's anonymous (Tier-0) — no API key or sign-up needed to read public rates.

Add to your client

Paste it into your assistant's MCP settings — ChatGPT connectors, Claude Desktop config, or Cursor.

Ask for a mortgage

“Find me the cheapest 5-year fix at 75% LTV.” Your AI calls the tools and answers with live data.

Configuration

Drop-in config for Claude & ChatGPT.

Streamable HTTP transport, no auth for public reads. When flag-gated OAuth 2.1 lands, only writes and user-specific data will require a token — public product reads stay open.

Works with any MCP-compatible client

Available tools

Four tools your assistant can call.

search_products

Filter live products by rate type, LTV, loan size and term. Returns matching mortgages with rates and fees.

compare_products

Side-by-side comparison of two or more products — rate, true cost over term, fees and ERCs.

get_product

Full record for one product, including the attributes detail: features, eligibility, lender quirks.

get_product_rates

Current rate and “as of” date for a product, so answers always cite a timestamp.
