che-word-mcp

A Swift-native MCP (Model Context Protocol) server for Microsoft Word document (.docx) manipulation. This is the first Swift OOXML library that directly manipulates Office Open XML without any third-party Word dependencies.

中文說明

Features

• Pure Swift Implementation: No Node.js, Python, or external runtime required
• Direct OOXML Manipulation: Works directly with XML, no Microsoft Word installation needed
• Single Binary: Just one executable file
• 234 MCP Tools: Comprehensive document manipulation across documents, tables, hyperlinks, headers, sections, styles, numbering, content controls, comments, footnotes, equations, fields, and Track Changes
• Office.js OOXML Roadmap P0 = 100%: All eight P0 sub-issues closed (umbrella #43). Surface coverage is now competitive with Office.js for the read/write side of every P0 capability.
• Round-trip silent corruption closed (v3.13.5, #56): 5 sub-stack-completion rounds (R5 / R5-CONT / R5-CONT-2 / R5-CONT-3 / R5-CONT-4) closed 30 findings (16 P0 + 21 P1) across rounds 4-8 of 6-AI cross-verification. Bumps ooxml-swift to v0.19.5 (v0.19.4 held back per verify-gate). No MCP source changes — fix architecture lives entirely in ooxml-swift. Round 4 walker symmetry across headers/footers/footnotes/endnotes (accept_revision / reject_revision / get_hyperlinks / replace_text reach all parts). Round 5 per-container relationships round-trip (update_hyperlink URL sync targets owning part rels). Round 6 delete_hyperlink mirror + container <w:tbl> capture preserved. Round 7 reject_revision typed clearMarker (file/API state convergence). Round 8 accept_revision typed clearMarker (mirror) + matrix-pin asymmetry-guard removal + Document.repairContainerFileNames marks document.xml.rels + [Content_Types].xml dirty. Convergence: Devil's Advocate wrote 5 adversarial tests targeting the convergence-cycle pattern; all PASSED. See closing summary and v3.13.5 release notes.
• Programmatic Track Changes (v3.12.0+, #45): Generate Word-native reviewable redlines via insert_text_as_revision / delete_text_as_revision / move_text_as_revision, plus as_revision: true flag on format_text / set_paragraph_format. Emits <w:ins> / <w:del> / <w:moveFrom> / <w:moveTo> / <w:rPrChange> / <w:pPrChange> markup. Side-effect contract: as_revision: true requires track changes enabled; throws track_changes_not_enabled otherwise (no silent auto-enable). Author resolution: explicit arg → revisions.settings.author → "Unknown".
• Tables / Hyperlinks / Headers extensions (v3.11.0+, #49 #50 #51): 16 new tools — table conditional styles (10 region types) / nested tables (max 5 deep) / explicit layout / table indent; three typed hyperlinks (URL / bookmark / email); even/odd header toggle / link-to-previous / get_section_header_map.
• Styles + Numbering + Sections foundation (v3.10.0+, #46 #47 #48): 19 new tools + 6 extended args — get_style_inheritance_chain, link_styles, set_latent_styles, add_style_name_alias, full Numbering CRUD lifecycle (definitions / overrides / list continuity / GC), section vertical alignment / page-number format / break-type / title-page distinction / per-section header references.
• Content Controls (SDT) read/write (v3.9.0+, #44): 7 new tools covering 12-type discrimination (richText / plainText / picture / date / dropDownList / comboBox / checkBox / bibliography / citation / group / repeatingSection / repeatingSectionItem). Nested SDT trees, deterministic max+1 SDT id allocator, keep_content unwrap on delete, whitelist-validated XML replacement.
• Save Durability Stack (v3.5.3+): atomic-rename save (#36), actor-based concurrency safety (#39), keep_bak opt-in rollback (#38), autosave_every Design B pre-mutation snapshot with explicit recover_from_autosave (#37, #40 v3.7.0). Default autosave_every: 1 (every mutation snapshots prior state). Pass autosave_every: 0 to opt out.
• Dual-Mode Access: Direct Mode (read-only, one step via source_path) and Session Mode (full lifecycle via doc_id)
• True Byte-preservation Round-trip Fidelity (v3.5.0+): save_document overlay mode uses WordDocument.modifiedParts dirty tracking — untouched typed parts (document.xml, styles.xml, fontTable.xml, header*.xml, footer*.xml, comments.xml, footnotes.xml, endnotes.xml) and unknown parts (theme/, webSettings.xml, people.xml, commentsExtended/Extensible/Ids, glossary/, customXml/) byte-for-byte preserved. NTPU thesis no-op save_document round-trip retains 13 fontTable entries + 6 distinct headers + 4 footers + three-segment PAGE field + <w15:presenceInfo> identity.
• Theme + Header/Footer/Watermark CRUD (v3.3.0+): word/theme/theme1.xml editing, header/footer enumeration + deletion, watermark VML detection. NTPU thesis Chinese font fix path: update_theme_fonts({ minor: { ea: "DFKai-SB" } }).
• Comment Threads + People + Notes Update + Web Settings (v3.4.0+): 13 tools for collaborative comment metadata, people.xml author records (dual identity: GUID + legacy author), in-place endnote/footnote editing (preserves IDs), webSettings.xml configuration.
• Full LaTeX Subset for insert_equation (v3.2.0+): Delegated to latex-math-swift. Supports \frac, \sqrt, \hat/\bar/\tilde accents, \left/\right delimiters, \sum/\int/\prod n-ary with bounds, function names, limits, \text{}, all Greek letters (including \varepsilon variants), and common operators.
• Text-Anchor Insertion: Insert captions / images relative to matched text (after_text / before_text), no pre-search call required
• Batch Operations: replace_text_batch / search_text_batch collapse N round-trips into one
• Session State API: SHA256 + mtime-based disk drift detection, revert_to_disk / reload_from_disk / check_disk_drift
• Structural Readback: list_captions / list_equations / update_all_fields (F9-equivalent) for manuscript review workflows
• Cross-platform: Works on macOS (universal binary x86_64 + arm64 since v3.5.1)

Version History

Quick Start

For Claude Desktop

Option A: MCPB One-Click Install (Recommended)

Download the latest .mcpb file from Releases and double-click to install.

Option B: Manual Configuration

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "che-word-mcp": {
      "command": "/usr/local/bin/CheWordMCP"
    }
  }
}

For Claude Code (CLI)

Option A: Install as Plugin (Recommended)

The plugin bundles a version-aware wrapper that auto-downloads the binary on first use (and re-downloads whenever the plugin itself is updated — no swift build needed).

Two steps — register the marketplace once, then install the plugin:

# 1. Register the marketplace (one-time)
claude plugin marketplace add PsychQuant/psychquant-claude-plugins

# 2. Install the plugin
claude plugin install che-word-mcp@psychquant-claude-plugins

Inside Claude Code? The slash-command equivalents /plugin marketplace add PsychQuant/psychquant-claude-plugins and /plugin install che-word-mcp@psychquant-claude-plugins work the same way.

Note: The plugin wraps the MCP binary with auto-download. If the binary is missing from ~/bin/CheWordMCP (or the sidecar ~/bin/.CheWordMCP.version is older than the plugin's pinned version), it will be downloaded from GitHub Releases on next invocation.

Option B: Install as standalone MCP

If you only need the MCP server without plugin features (slash commands, skills, SessionStart hooks):

# Create ~/bin if needed
mkdir -p ~/bin

# Download the latest release
curl -L https://github.com/PsychQuant/che-word-mcp/releases/latest/download/CheWordMCP -o ~/bin/CheWordMCP
chmod +x ~/bin/CheWordMCP

# Register with Claude Code
# --scope user    : available across all projects (stored in ~/.claude.json)
# --transport stdio: local binary execution via stdin/stdout
# --              : separator between claude options and the command
claude mcp add --scope user --transport stdio che-word-mcp -- ~/bin/CheWordMCP

💡 Tip: Install the binary into a local directory like ~/bin/. Avoid cloud-synced folders (Dropbox, iCloud, OneDrive) — their sync operations can break MCP connections.

Build from Source (Optional)

Use this only if you want to track main or contribute patches.

Prerequisites

• macOS 13.0+ (Ventura or later)
• Swift 5.9+

git clone https://github.com/PsychQuant/che-word-mcp.git
cd che-word-mcp
swift build -c release

# Install
cp .build/release/CheWordMCP ~/bin/

Two Modes of Operation

Direct Mode (source_path) — Read-only, no state

Pass a file path directly. No need to call open_document first. Best for quick inspection.

# Just pass source_path — one step
list_images: { "source_path": "/path/to/file.docx" }
search_text: { "source_path": "/path/to/file.docx", "query": "keyword" }
get_document_info: { "source_path": "/path/to/file.docx" }

19 tools support Direct Mode:

Session Mode (doc_id) — Full read/write lifecycle

Call open_document first, then use doc_id for all subsequent operations. Required for editing.

open_document: { "path": "/path/to/file.docx", "doc_id": "mydoc" }
insert_paragraph: { "doc_id": "mydoc", "text": "Hello World" }
save_document: { "doc_id": "mydoc", "path": "/path/to/output.docx" }
close_document: { "doc_id": "mydoc" }

Dual-mode tools accept both source_path and doc_id. If you already have a document open, use doc_id to avoid re-reading from disk.

Usage with AI Agents

Just ask the agent

Use che-word-mcp to read all images from ~/Documents/report.docx

The agent will automatically use Direct Mode (no need to open/close).

## Word Document Manipulation

Use `che-word-mcp` for reading and writing Microsoft Word (.docx) files.

**Read-only** (Direct Mode — one step):
- `get_document_text` / `get_paragraphs` — read content
- `list_images` / `search_text` — inspect elements
- `export_markdown` — convert to Markdown

**Edit** (Session Mode — open→edit→save):
1. `open_document` → get doc_id
2. `insert_paragraph` / `replace_text` / `format_text` — modify
3. `save_document` → write to disk
4. `close_document` → release memory

Paragraph Index Conventions

paragraph_index / index are historical parameter names and do not always count the same OOXML surface. Different insert / mutate / readback tools use different conventions — there is no universal default to assume. Three coordinate systems coexist: body.children insertion index (used by some inserts), top-level paragraph ordinal (used by most mutate operations and inline equation insertion), and get_paragraphs readback order (for inspection). See docs/paragraph-index-conventions.md for the per-tool inventory before reusing an index across tools.
