Subaio Launches MCP Server to Connect AI Assistants with Real-Time Bank Data

Danish fintech Subaio has launched an MCP server to bridge the gap between bank account data and AI assistants like ChatGPT and Claude. While North American banks move to block AI agents, this integration uses regulated open banking to provide AI with real-time financial context, enabling precise budgeting and financial planning for Danish users.

What was announced

Subaio is opening its Model Context Protocol (MCP) server to the Danish market, providing a standardized gateway for AI assistants to access financial data. This allows private individuals and companies to connect their bank accounts to Large Language Models (LLMs) to receive answers based on actual transaction history rather than statistical guesswork. The service is available for free to individuals via monaio.dk, while corporate users are required to pay. Subaio has indicated that other European markets are expected to follow this initial launch.

The technical implementation relies on PSD2-regulated open banking rather than the credential-sharing or "screen scraping" methods recently blocked by major banks in the United States and Canada. Under this model, the AI assistant never receives the user’s bank login details and lacks the authority to transfer funds. Access is granted only through explicit user consent. Subaio’s proprietary engine, which has been operational within major European banks for ten years, processes the raw data by cleaning cryptic transaction strings and identifying recurring payments and subscriptions. This allows users to ask complex questions regarding their job changes, spending habits, and potential savings. Subaio is currently in discussions with several large Nordic banks, with expectations that the first white-labeled versions of this technology will be available to bank customers by 2026.

"For years the industry has talked about AI that understands your money. It never could, because it had never seen your money. As of this morning, it can,"

Thomas Laursen, CEO and co-founder of Subaio

The companies involved

Subaio is a Denmark-based fintech that specializes in subscription management and transaction enrichment. For a decade, the company has focused on transforming raw banking data into clear, actionable insights for financial institutions across the Nordics and wider Europe. Its core technology is designed to help consumers manage their recurring costs and help banks provide more transparent digital banking experiences. The firm’s engine is already in production at some of the largest financial institutions in the Nordic region, where it handles the categorization and identification of merchant data at scale.

The company has established itself as a key player in the European open banking ecosystem through significant industry collaborations. This includes a strategic partnership with Snowdrop Solutions aimed at advancing data-driven banking capabilities. Additionally, Subaio has previously integrated with open banking platform Aiia to automate creditworthiness assessments for financial institutions. These partnerships reflect Subaio’s position as a middle-layer provider that connects regulated banking infrastructure with modern consumer-facing applications. By acting as the bridge between raw bank data and user-facing AI, the company aims to position itself at the center of the emerging "agentic" finance sector.

What FF News has reported before

FF News has previously covered Subaio’s efforts to enhance the utility of banking data through strategic industry alliances. In 2025, the publication reported on how Subaio and Snowdrop Solutions Enter Strategic Partnership to Advance data-driven Banking, a move intended to refine the way banks present transaction data to their customers. Prior to this, FF News detailed the company's technical expansion in a report on how Subaio chooses open banking firm Aiia to automate creditworthiness for financial institutions. This earlier collaboration focused on using automated data retrieval to streamline the lending process, highlighting Subaio’s long-term commitment to the open banking framework and its role in automating complex financial assessments.

What this means

This move signals a significant shift in the global battle for the "financial interface." While North American incumbents are retreating into a defensive posture by blocking AI agents to protect account security, European fintechs are leveraging the PSD2 framework to invite AI into the ecosystem through regulated channels. This creates immediate competitive pressure on traditional banks. If institutions do not provide sophisticated AI tools within their own proprietary channels, they risk becoming "dumb pipes" while the high-value advisory relationship moves to third-party LLMs. The use of MCP as an open standard suggests that the future of personal finance may lie in interoperability rather than closed banking ecosystems.
