Vespper DOCX MCP lets AI agents read .docx files as HTML and apply edits using Word tracked changes while preserving styling and formatting. The service claims to be 2.7–3.5× faster and 2.7–2.9× cheaper than comparable DOCX skills, with higher accuracy and lower latency. It offers three tools—a Microsoft Word add‑in, an ONLYOFFICE chat plugin, and a browser app with EigenPal’s docx‑editor—each presenting AI suggestions as editable cards or tracked changes. Pricing starts with a free tier and scales with usage, offering 5,000 edits per month and options for higher volume, dedicated Slack support, and enterprise deployment including on‑premise or VPC‑isolated setups. Enterprise plans can provide zero‑data‑retention and self‑hosting, with guided onboarding for secure integration. GateOnAI Score: 62/100. ### What is Docling?
