docx-mcp

Give your AI coding agent the ability to create, read, and edit Word documents. Every edit appears as a tracked change in Microsoft Word — red strikethrough for deletions, green underline for insertions, comments in the sidebar — so your colleagues see exactly what changed and why.

Who This Is For

Professionals who produce Word deliverables and want their AI agent to handle the document work directly:

• Legal — contract review with tracked redlines, batch clause replacement across templates, comment annotations explaining each change, footnote management
• Security & Penetration Testing — generate pentest reports from markdown findings, merge appendices from multiple engagements, add executive-summary comments, remove DRAFT watermarks before delivery
• Consulting — build proposals and SOWs from templates, convert meeting notes to formatted deliverables, bulk-update payment terms across document sets
• Compliance & Audit — structural validation of document integrity, cross-reference checking, heading-level audits, protection enforcement

What You Can Ask Your Agent To Do

Review a contract:

"Open contract.docx, find every instance of 'Net 30', change it to 'Net 60', and add a comment on each explaining it was updated per Amendment 3. Save as contract_revised.docx."

Generate a report from markdown:

"Convert my pentest-findings.md to a Word document using the client's report template. Add footnotes for each CVE reference."

Batch-edit a template library:

"Open the MSA template, replace 'ACME Corp' with 'GlobalTech Inc' everywhere, update the effective date in the header, and set document protection to track-changes-only."

Audit a document before sending:

"Open the final deliverable, run a structural audit, check for any DRAFT or TODO markers, validate all footnote cross-references, and remove any watermarks."

Your agent handles the entire workflow — opening the file, navigating the structure, making precise edits with full revision history, validating integrity, and saving — while you focus on the substance.

Installation

Claude Code (recommended):

claude mcp add docx-mcp -- uvx docx-mcp-server

That's it. A companion skill auto-installs the first time the server starts, teaching Claude the document editing workflow, OOXML pitfalls, and audit checklist. It auto-updates on every upgrade.

Capabilities

Example: Contract Review with Redlines

1. open_document("services-agreement.docx")
2. get_headings()                              → see document structure
3. search_text("30 days")                      → find the payment clause
4. delete_text(para_id, "30 days")             → tracked deletion  (red strikethrough)
5. insert_text(para_id, "60 days")             → tracked insertion (green underline)
6. add_comment(para_id, "Extended per client request — see Amendment 3")
7. audit_document()                            → verify structural integrity
8. save_document("services-agreement_redlined.docx")

Open the output in Word and you see exactly what a human reviewer would produce — revision marks, comments in the margin, clean document structure.

Example: Pentest Report from Markdown

1. create_from_markdown("pentest-report.docx",
       md_path="findings.md",
       template_path="client-template.dotx")
2. audit_document()                            → verify integrity
3. save_document()                             → ready for delivery

Your markdown findings — headings, tables of affected hosts, code blocks with proof-of-concept output, severity ratings — become a formatted Word document matching the client's template. Smart typography is applied automatically (curly quotes, em dashes, proper ellipses).

How It Works

A .docx file is a ZIP archive of XML files. This server unpacks the archive, edits the XML directly, and repacks it. This is what gives it the ability to produce real tracked changes, comments, and footnotes — things that higher-level document libraries can't do.

Every edit is validated against the OOXML specification before saving, catching issues like orphaned footnotes, duplicate internal IDs, and broken cross-references that would otherwise cause Word to "repair" (and silently rewrite) your document.

Requirements
