MPowered has become the first UK mortgage lender to make its affordability calculator available to large language models (LLMs).
MPowered says the move marks a major step towards an 'LLM-first mortgage journey', enabling real-time affordability checks through AI agents like Claude.
By launching its affordability calculator as a Model Context Protocol server, MPowered has made its lending criteria natively accessible to LLMs. This allows AI agents to interact with the calculator in real time, returning tailored borrowing estimates without relying on static websites, screen scraping, or outdated third-party summaries.
MPowered says that as AI personal assistants become the "primary interface to the internet, websites will increasingly be visited by LLMs, not humans". These models will query data, interpret context, and return answers directly to users in natural language.
Jake Atkinson, director of growth at MPowered, commented: “We’re not just optimising for mobile or web anymore, we’re actively building for an LLM-first internet. This is about making sure that when your AI assistant goes looking for mortgage information, it can talk directly to the source. Safely, accurately, and in context."
Director of AI at MPowered, Stelios Constantinidis, added: “The MCP is rapidly becoming the standard for how models safely interface with live, trusted data sources. MPowered’s move sets a new precedent for how financial institutions can surface core functionality to AI, while maintaining full control over data integrity and context."
