What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI assistants like Claude and ChatGPT to securely access external data sources. With AccountsOS MCP integration, you can ask questions about your accounts, query transactions, and check deadlines directly in your AI chat.

Your API key never leaves your local machine, and all requests are authenticated end-to-end.
