Che Word

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
• 233 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

Version	Date	Changes
v3.13.5	2026-04-27	R5 stack-completion (closes #56 silent corruption). Bumps ooxml-swift v0.19.3 → v0.19.5 (v0.19.4 held back per verify-gate). 30 findings closed (16 P0 + 21 P1) across 5 sub-stacks (R5 / R5-CONT / R5-CONT-2 / R5-CONT-3 / R5-CONT-4) and rounds 4-8 of 6-AI cross-verification. 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 + repairContainerFileNames rels-dirty. Convergence: Devil's Advocate wrote 5 adversarial tests targeting the convergence-cycle pattern; all PASSED. No che-word-mcp source changes — entire fix architecture in ooxml-swift. See closing summary.
v3.13.4	2026-04-26	(skipped — held back per verify-gate). R3 stack content rolled into v3.13.5.
v3.13.3	2026-04-26	Bumps ooxml-swift v0.19.2 → v0.19.3. Closes 8 P0 + 3 must-fix P1 from #56 round-2 verify (Hyperlink API path visual-style restoration / tgtFrame / docLocation Reader filter / ordered children source-order preservation; sort-path contentControls + commentIds / footnoteIds / endnoteIds / hasPageBreak emission; non-text wrapper preservation; nested hyperlink/SDT/fieldSimple round-trip; nextBookmarkId calibration; bookmark wrap-around restoration). No source changes.
v3.13.2	2026-04-26	Bumps ooxml-swift v0.19.1 → v0.19.2. Closes 4 blocking findings from #56 round-1 verify (F1 Hyperlink.toXML() emits Reader-collected runs/rawAttributes/rawChildren; F2 add_bookmark/delete_bookmark sync bookmarkMarkers; F3 ins/del/moveFrom/moveTo round-trip preserves position+revisionId+wrapper; F4 namespace preservation extends from document.xml to header/footer/footnote/endnote). No source changes.
v3.13.1	2026-04-25	pPr double-emission silent regression on sort-by-position round-trip — hot-fix (ooxml-swift v0.19.1).
v3.13.0	2026-04-25	document.xml lossless round-trip + tool-mediated wrapper edits (closes #56 P0). Hybrid model preserves namespace map (34 xmlns), bookmarks, structural wrappers (<w:hyperlink> / <w:fldSimple> / <mc:AlternateContent>).
v3.12.0	2026-04-25	Programmatic Track Changes generation (closes #45) — 3 new tools (insert_text_as_revision / delete_text_as_revision / move_text_as_revision) + as_revision flag on format_text / set_paragraph_format. Emits <w:ins> / <w:del> / <w:moveFrom> / <w:moveTo> / <w:rPrChange> / <w:pPrChange> markup.
v3.11.0	2026-04-25	Tables / Hyperlinks / Headers extensions (closes #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.
v3.10.0	2026-04-24	Styles + Numbering + Sections foundation (closes #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; section vertical alignment / page-number format / break-type / title-page distinct / per-section header refs.
v3.9.0	2026-04-24	Content Controls (SDT) read/write (closes #44) — 7 new tools, 12-type discrimination (richText / plainText / picture / date / dropDownList / comboBox / checkBox / bibliography / citation / group / repeatingSection / repeatingSectionItem). Nested SDT trees, deterministic id allocator, keep_content unwrap, whitelist-validated XML replacement.
v3.8.0	2026-04-24	Header/footer raw-element preservation + counter-isolation flag (closes #52).
v3.7.2	2026-04-24	3-issue bundle from #42 verification (closes #53, #54, #55 path traversal hardening).
v3.7.1	2026-04-24	update_all_fields no longer strips headers/footers (closes #42).
v3.7.0	2026-04-24	Insert crash hardening + autosave Design B (closes #40, #41). v3.6.0 shipped autosave_every Design A (post-mutation counter) which couldn't preserve K-1 mutations on crash at K when K%N≠0. v3.7.0 switches to Design B (snapshot fires at the START of every mutating handler before the mutation runs); default autosave_every flipped from 0 to 1 (every mutation snapshots prior state). Pass autosave_every: 0 to opt out. BREAKING (effective): callers who relied on Design A semantics or default disabled. Also adds Phase A CHE_WORD_MCP_LOG_LEVEL=debug structured logging gate for #41 investigation. Built on ooxml-swift 0.13.3 which kills DocxReader.concurrentPerform (parsing determinism prerequisite for recover_from_autosave) and refactors nextImageRelationshipId to use the rId allocator. Migration from v3.6.0: code passing autosave_every: 0 explicitly is unaffected; code that omitted the arg now gets 1 (full safety) — to restore v3.6.0 disabled-by-default behavior, add autosave_every: 0 to open_document calls.
v3.6.0	2026-04-23	Autosave + checkpoint + recover_from_autosave (closes #37). open_document gains autosave_every: Int = 0 parameter — when N > 0, every Nth mutation triggers a checkpoint write to <source>.autosave.docx (separate file, NOT eager-save to source). New tools: checkpoint(doc_id, path?) for manual snapshot, recover_from_autosave(doc_id, discard_changes?) to replace in-memory state with autosave bytes. get_session_state adds autosave_detected + autosave_path fields. Successful save_document / finalize_document cleans up <source>.autosave.docx. Phase 4 of save-durability-stack SDD.
v3.5.5	2026-04-23	keep_bak opt-in for rollback escape hatch (closes #38). save_document gains optional keep_bak: Bool = false; when true and target exists, server renames target → <path>.bak BEFORE atomic-rename save (single slot, overwrites prior .bak). User can mv <path>.bak <path> to roll back if a future save ships silent OOXML damage. .bak lives at server layer NOT ooxml-swift — macdoc CLI users don't get unwanted .bak files. Phase 3 of save-durability-stack SDD.
v3.5.4	2026-04-23	class WordMCPServer → actor WordMCPServer (closes #39). 8 mutable session state dictionaries become actor-isolated; compiler enforces every cross-actor access via await. Eliminates the Dictionary hash-table corruption race that pre-v3.5.4 12-parallel insert_image_from_path calls triggered. Phase 2 of save-durability-stack SDD.
v3.5.3	2026-04-23	Atomic-rename save (closes #36). Bumps to ooxml-swift 0.13.2 which refactors DocxWriter.write to write <url>.tmp.<UUID> + fsync + replaceItemAt. Any throw or process kill mid-write leaves the original byte-preserved (POSIX rename(2) is kernel-atomic; cross-volume falls back to copy+delete). 397/397 ooxml-swift tests pass; concurrent-observer regression test added. Phase 1 of save-durability-stack SDD.
v3.5.2	2026-04-23	Rels overlay merge (closes #35) — Reader-loaded NTPU thesis no-op save_document round-trip now preserves theme / webSettings / people / customXml / commentsExtended / commentsIds rels. v3.5.0/v3.5.1 fixed the parts layer; v3.5.2 fixes the rels layer. No che-word-mcp source change — fix entirely in ooxml-swift v0.13.1 (RelationshipsOverlay + relationship-driven extractImages).
v3.5.1	2026-04-23	Universal binary (x86_64 + arm64) — restores Intel Mac compatibility. v3.5.0 was arm64-only because release-build skipped the documented lipo -create step. No source changes — drop-in replacement.
v3.5.0	2026-04-23	True byte-preservation via dirty tracking (closes #23 round-2 + #32 #33 #34). Reader-loaded NTPU theses survive no-op save_document round-trip with all 13 fontTable + 6 distinct headers + 4 footers + three-segment PAGE field + <w15:presenceInfo> identity preserved. Built on ooxml-swift 0.13.0 (modifiedParts: Set<String> + Header.originalFileName + overlay-mode skip-when-not-dirty). list_people returns dual identity: person_id (GUID, stable across rename) + display_name_id (= author legacy).
v3.4.0	2026-04-23	Phase 2B + 2C combined (closes #24 #25 #29 #30 #31): comment threads (list_comment_threads / get_comment_thread / sync_extended_comments), people (list_people / add_person / update_person / delete_person), notes update (get_endnote / update_endnote / get_footnote / update_footnote — preserves note IDs), web settings (get_web_settings / update_web_settings). 13 new MCP tools.
v3.3.0	2026-04-23	Phase 2A (closes #26 #27 #28): theme tools (get_theme / update_theme_fonts / update_theme_color / set_theme), headers (list_headers / get_header / delete_header), watermarks (list_watermarks / get_watermark), footers (list_footers / get_footer / delete_footer). 12 new MCP tools. Bumped to ooxml-swift 0.12.x for preserve-by-default round-trip.
v3.2.0	2026-04-23	insert_equation LaTeX parser delegated to latex-math-swift (closes #22). Full LaTeX subset: \frac, \sqrt, \hat/\bar/\tilde, \left/\right, \sum/\int/\prod with bounds, \ln/\sin/\cos/\tan/\log/\exp/\max/\min/\det, \sup/\inf/\lim, \text{}, all Greek letters (incl. \varepsilon variants), common operators. 18 econometrics fixture equations now all parse. Adds MathAccent via ooxml-swift 0.11.0.
v3.1.0	2026-04-22	9 readback tools: Caption CRUD (list_captions / get_caption / update_caption / delete_caption), update_all_fields (F9-equivalent SEQ recount), Equation CRUD (list_equations / get_equation / update_equation / delete_equation). Built on new ooxml-swift 0.10.0 FieldParser + OMMLParser.
v3.0.0	2026-04-22	BREAKING: session state API. New tools get_session_state / revert_to_disk / reload_from_disk / check_disk_drift. open_document track_changes default flipped from true to false. close_document dirty-check now returns E_DIRTY_DOC text response with recovery options (save_document / discard_changes: true / finalize_document).
v2.3.0	2026-04-22	Text-anchor compound tool — insert_caption / insert_image_from_path accept after_text / before_text / text_instance. Eliminates the search_text + insert_* two-call pattern (~50% RPC reduction for thesis caption workflows).
v2.2.0	2026-04-22	Batch API — replace_text_batch (sequential, single save at end, dry_run/stop_on_first_failure flags) + search_text_batch (aggregated multi-query response, Direct + Session Mode).
v2.1.0	2026-04-22	Expose v2.0.0 params via inputSchema — schemas for insert_caption / insert_equation / insert_image_from_path / replace_text now advertise new params (Chinese labels, components, into_table_cell, scope, regex).
v2.0.0	2026-04-22	BREAKING: word-mcp-insertion-primitives Spectra change. Real OOXML SEQ fields (was literal text), OMML MathComponent AST (was string substitution), auto-aspect image sizing + table-cell target, cross-run-safe replace_text with scope + regex backreferences.
v1.19.0	2026-04-15	Manuscript review markdown export: export_revision_summary_markdown / compare_documents_markdown / export_comment_threads_markdown. BREAKING: get_revisions + compare_documents full_text param replaced by summarize (inverted default).
v1.18.0	2026-04-14	Fix get_revisions hardcoded 30-char truncation (bug since v1.2.0); add full_text opt-in.
v1.17.0	2026-03-11	Session state management: dirty tracking, autosave, finalize_document, get_document_session_state, shutdown flush (contributed by @ildunari)
v1.16.0	2026-03-10	Dual-Mode: 15 read-only tools now support source_path (Direct Mode); MCP server instructions added

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" }

18 tools support Direct Mode:

Category	Tools
Read content	get_text, get_document_text, get_paragraphs, get_document_info, search_text
List elements	list_images, list_styles, get_tables, list_comments, list_hyperlinks, list_bookmarks, list_footnotes, list_endnotes, get_revisions
Properties	get_document_properties, get_section_properties, get_word_count_by_section
Export	export_markdown

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).

AGENTS.md / CLAUDE.md

## 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

Tool	Description
update_content_control_text	Replace text content of plainText / richText / date / bibliography / citation SDTs. Preserves <w:sdtPr> byte-identical. Returns unsupported_type for picture / dropdown / combo / checkbox / group / repeatingSection.
replace_content_control_content	Replace full <w:sdtContent> XML with whitelist validation (rejects input containing <w:sdt>, <w:body>, <w:sectPr>, or XML declaration)

Developer Notes — Real-World Fixture Testing

Tests/CheWordMCPTests/RealWorldDocxRoundTripSmokeTests.swift validates the ooxml-swift Reader / Writer pair against real-world Word output (e.g., academic theses, contracts) rather than synthesized fixtures. Drop confidential .docx files into test-files/ (gitignored — they never reach version control), then:

cd mcp/che-word-mcp
swift test --filter RealWorldDocxRoundTripSmokeTests

Per-fixture assertions: xmllint --noout clean, bookmark / hyperlink / fldSimple / AlternateContent count parity, SHA256 of concatenated <w:t> content matches. The test silently XCTSkips when test-files/ is empty so clean clones / CI do not false-fail. Mirrors the .note smoke pattern from PsychQuant/macdoc#81.
