Could you build this?

Partial Exposing a Model Context Protocol (MCP) server is simple, but building a fully compliant, rich in-browser DOCX editor that parses and serializes OpenXML without formatting loss is notoriously difficult.

What it would actually take: Requires an engine capable of bidirectional translation of Microsoft OpenXML (.docx) into an internal rich-text document model (like ProseMirror or Slate) and back without corruption. An accompanying MCP server exposes fine-grained editing tools that manipulate document AST nodes safely. Substantial expertise in word processing document object models and OOXML standard quirks is required.
