Extend MCP: documents into structured data from your AI app

Turn documents into structured data from your AI app: Extend can parse a file, extract fields, classify documents, split a bundle into parts and fill PDF forms. ContextGate connects Extend's MCP server to Claude, ChatGPT and Cursor, and a policy can hide personal data found in the invoices, contracts or forms you run through it.
