Show HN: MCP server ONLY app for personal finances (passage.money)

A new app called Passage has been launched, designed to provide users with secure and personalized financial analysis by connecting their financial data to large language models (LLMs) like ChatGPT, Claude, Grok, or Gemini. This approach enables users to receive tailored advice while ensuring full control over what data they choose to input, and guaranteeing that their financial credentials are never stored by the app itself. Users can manage their financial data meaningfully, deciding which pieces remain accessible for analysis and which are deleted permanently. The significance of Passage lies in its promise of unbiased financial analysis combined with stringent privacy measures, addressing ongoing concerns in the AI/ML community regarding data security and user control. Built by engineers from Plaid—a leading fintech company known for linking numerous U.S. bank accounts—Passage is backed by enterprise-grade security protocols. By allowing users to harness the analytical power of advanced LLMs without the risk of data compromise, Passage aims to innovate personal finance management and potentially reshape how AI systems interact with sensitive financial information.
