Vespper launches DOCX MCP: 3x faster, 2x cheaper, more accurate Word editing for agents

Launch HN: Vespper (YC F24) – SOTA Docx MCP

Vespper (YC F24) launches DOCX MCP, the first model fine-tuned specifically for editing Word documents, shipped as an MCP server. On internal benchmarks, it claims 3x faster, 2x cheaper, and more accurate agentic editing than alternatives. The approach round-trips .docx through Markdown to avoid low-level SDKs and complex DSLs, but uses a fine-tuned model to fix the lossy conversion problem. The post does not disclose benchmark scores, pricing, or the base model.
