MCP stands for Model Context Protocol. It’s the way Claude and ChatGPT connect to outside tools and data, like how your phone connects to apps.

Pennyweight uses MCP to give your AI secure access to your financial data. You don’t need to understand the protocol. You click connect, authorize your bank accounts, and tag which accounts belong to which entity. The MCP handles the rest.
