AI-native surgical editing of Word and OpenDocument files with formatting preservation

Safe Docx is a local, stdio-based MCP server (npm-distributed, Apache-2.0) built for coding agents, offering surgical, format-preserving edits to .docx/.odt files with conformance evidence for OOXML compatibility. It is not suited as a visual editor or collaboration tool.
Safe Docx is a local MCP server and CLI for reading, searching, editing, comparing, converting, and saving .docx and .odt files. Distributed via the npm package @usejunior/safe-docx over stdio, it preserves document structure and can produce clean or tracked-changes output. The project is Apache-2.0 licensed and publishes ECMA-376 / OOXML conformance reports. No tool names are listed in the source material, so the tool list is left empty.
Setup
Install globally with npm install --global @usejunior/safe-docx, then configure your MCP client with the installed executable's absolute path. For Claude Code: claude mcp add safe-docx -- /absolute/path/to/safe-docx.
Fit and risk
Not for
- Visual editing scenarios needing browser rendering, real-time collaboration, or pixel-level pagination guarantees
- Using .dotx templates directly (they must be converted to .docx first)
Required permissions
- Filesystem access to read and write local .docx / .odt documents
Risks and side effects
- Edits apply to local files; incorrect targeted changes could overwrite original content — use the clean/tracked-changes dual output for review
- The project is not a visual editor or layout engine, so complex layout results should be verified manually
Troubleshooting
- Verify the npm package is globally installed and the client uses the executable's absolute path
- Ensure .dotx templates were converted to .docx before use
- See docs/installation.md in the repository for version pinning and client configuration
Use cases
Have a coding agent make targeted edits to a .docx (e.g., change the governing-law clause in an NDA) and save both clean and tracked-changes copies
Search, compare, and convert Word / OpenDocument files
