A free DOCX editor with a built-in MCP server landed on Show HN — AI agents can now read and edit Word documents through the Model Context Protocol.
The server exposes document editing as callable MCP tools, so any compatible client — Claude Code, Cursor, Gemini CLI — can open, modify, and save .docx files without a human touching Word.
What shipped:
- Free DOCX editor with MCP server integration
- Agent-driven editing — AI clients call the server to manipulate Word documents programmatically
- Show HN reception — 13 points, 1 comment as of posting
This sits in a small but growing niche. safe-docx (Apache-2.0) runs locally and works with Claude Code, Gemini CLI, and Cursor, preserving tracked changes and comments. The difference: revise.io pairs its MCP server with an editor interface, so you can inspect what the agent changed before the file ships.
NOTE
DOCX MCP servers are early. Basic text edits hold up, but complex formatting — tables, embedded images, custom styles — may not survive every round-trip. Test on a copy before trusting an agent with a real document.
Revise.io’s MCP server is free and live now. Configuration steps are in their help docs.
