Denmark's Subaio Launches MCP Server Linking Bank Accounts to AI Assistants

Danish fintech Subaio, whose transaction categorization engine is used by banks including ABN AMRO, Nordea and Nykredit, has launched an MCP server that lets individuals and businesses connect their bank accounts to AI assistants such as ChatGPT and Claude through PSD2 open banking. The company says access is read-only, requires no sharing of banking credentials, and does not permit money transfers. The launch was announced on 6 November 2026.

The move contrasts with a wave of restrictions during October, when several large North American banks blocked external AI agents from customer accounts. Subaio's service is currently free for individuals in Denmark via monaio.dk and paid for corporate users; the company also says the server is designed so banks can offer it white-label to their own customers. Vendor-reported: Subaio states it is in dialogue with several large Nordic banks, with a first launch expected during 2026. Subaio positions the server as a controlled alternative to outright blocking of AI access to banking data.
