BankBridge - Your AI agent, on your real bank data
BankBridge lets your AI agent answer questions about your real bank data. It is a hosted MCP (Model Context Protocol) server that gives Claude, ChatGPT, Cursor, Gemini CLI, OpenAI Codex, Windsurf and 22 other agent hosts read-only access to your bank accounts, transactions and investment holdings.
Connect your banks once through a secure link flow, then ask your agent about spending by category or merchant, recurring subscriptions, monthly cashflow, or your portfolio with gain/loss. Twelve tools ship out of the box. Every query fetches live data; BankBridge stores no transactions, balances or holdings.
Auth supports bearer keys for solo setups and OAuth 2.1 with Dynamic Client Registration and PKCE for multi-user apps. Pricing: $5/mo or $50/yr per connected bank, cancel any time. Built by Great Work LLC.
