Aggregate connects a person's or company's financial accounts (banks and cards through Plaid, Stripe, Shopify, Square, QuickBooks, Xero, BILL, payroll and more) and gives their AI assistant, such as Claude or ChatGPT, accurate, reconciled numbers through the Model Context Protocol (MCP).

Access to every provider is read-only: Aggregate can't move money. Each AI sees only what the customer grants, every request is logged, and access can be revoked in one click. Hosted in the US (Fly.io; Neon on AWS us-east-1). Open source under AGPL-3.0 and self-hostable. Free during beta.
