Safe Docx is a local MCP server and CLI for reading, searching, editing, comparing, converting, and saving document files. It preserves DOCX structure and can produce clean or tracked-changes output.
Example
Ask your coding agent:
Safe Docx finds the clause, applies the targeted edit, and writes both files for review. The rest of the document stays outside the requested edit.

Install
Then configure your MCP client with the installed executable's absolute path. For Claude Code:
Antigravity CLI
Add Safe Docx to ~/.gemini/config/mcp_config.json:
Restart agy, then ask it to edit a .docx file. Antigravity may ask you to approve the MCP server before first use.
See Installation and verification for locating the executable, pinning a version, and configuring clients.

Standards Conformance
Browse the Safe Docx Conformance Explorer to navigate ECMA-376 sections, OOXML schema declarations, capability claims, explicit non-goals, and measured cross-implementation outcomes.
The generated repository conformance report remains the source-controlled record of targeted sections, non-goals, and verification references.
What Safe Docx Is Not Optimized For
Safe Docx is not a visual editor or layout engine. It does not provide browser rendering, real-time collaboration, or pixel-level pagination guarantees. .dotx templates must be converted to .docx before use.
