Safe Docx — Claude Code MCP server: what it does, how to install
Local document manipulation server for coding agents handling .docx and .odt files. It performs targeted edits while keeping layout intact.
claude mcp add safe-docx -- npx -y @usejunior/safe-docxWhat Safe Docx does
The server runs on your machine over standard I/O, giving agents dedicated tools to inspect and modify office files. Assistants can locate clauses with grep or update phrasing via replace_text without stripping underlying styles. Processing happens locally.
Revision handling lets the model produce both an untouched clean copy and an annotated draft containing revision marks. Beyond text adjustments, it manages footnotes and exports to .odt.
Templates ending in .dotx must be resaved as .docx first, because the server does not parse them directly. The tool avoids visual page rendering, so it cannot ensure exact line-by-line pagination.
What it helps with
- update legal terms in contracts while preserving existing formatting
- generate separate clean and revision-marked versions of a draft
- search sections and retrieve outlines inside Word documents
- insert comments or footnote citations directly via agent prompts
- convert Word files into
.odtformat on the local machine
Example prompts for the agent
- Update the jurisdiction clause in
contract.docxto Delaware and output a version with tracked edits. - Search for payment terms in
order.docxand add a comment to that paragraph. - Export the modified file
brief.docxto.odt.
