# Vespper

> Vespper (YC F24) builds infrastructure that lets AI agents produce real Microsoft Word documents. Its product is a docx MCP (Model Context Protocol) server that turns raw agent output into clean, tracked, review-ready .docx files - aimed at regulated, legal, and compliance workflows where the final artifact has to be a Word doc with tracked changes, not a chat window. The two-person, Tel Aviv-based team originally launched an open-source, 24/7 AI on-call engineer for incident triage before pivoting into agent document infrastructure.
