What it can do
Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.
document_openOpen one of the demo files by name: documents footnotes, comments, forms, rtl, wild-horse, workshop, offer, tools; workbooks workbook, functions, macros, queries, gep, vba-web, sqlite, order-desk, onrr, cashflow, pivot, chart, notes, check, xtools. Default is footnotes. For your
document_open_fileOpen YOUR file in a private editor cabin for this session: a .docx/.doc/.odt document or an .xlsx/.xlsm/.xlsb/.xls/.ods workbook, up to 50 MB. Give exactly one of: url (https link the server can fetch), base64 (file bytes; then name with the extension is required). Nothing in the
document_describeName, pages, paragraphs, words, number of comments and tracked changes, whether track changes is on. For documents; call first.
document_readParagraph text as a window: from = index of the first paragraph (0-based), count = how many (max 40). The answer carries next — where to continue, null at the end. A missing paragraph is a refusal, not an invention.
document_findParagraphs containing the text (case-insensitive), with snippets around the match.
document_commentsComments (author, text, anchor, resolved) and tracked changes — up to 50.
document_propose_replacementPropose the full new text of one paragraph (paragraph_index from document_read). Nothing changes yet: the editor core builds the change on a copy and returns before/after plus checks (numbers, dates, links kept). Then call document_apply with the proposal_id. Read the paragraph f
document_applyApply a proposal from document_propose_replacement to the document in this session's cabin (not to your original file). Stale proposal (the document moved on) is refused by the engine — propose again. Repeating an applied proposal is a no-op.
sheet_describeWorkbook overview: every sheet tab with its used range, the current revision, and the header row of the sheet that is open. Call this first, then pass the tab name you need as "sheet" to sheet_read and sheet_find.
sheet_readRead a rectangular range like A1:F20 (max 60 rows × 26 columns): values and formulas. Empty cells are omitted. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet — without it you read whichever sheet happens to be open, and the answer will quiet
sheet_findFind cells whose value or formula contains the text (case-insensitive) in the used range of a sheet. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet: without it only the sheet that happens to be open is searched.
macro_listList VBA modules and runnable macros (entry points) in this workbook with their route and blockers. Runs nothing.
macro_read_sourceRead the source text of one procedure (module + procedure name from macro_list). Read-only; runs nothing.
macro_planPlan a macro run without running it: route, whether the engine can run it natively, blockers, instruction budget.
query_listList Power Query queries in this workbook: names, step chain, load target, connections. Reads only; refreshes nothing.
query_explainExplain one Power Query query by name: its steps in order, where it loads, its connection. Reads only; refreshes nothing.
workbook_inspectMap the whole application model of this workbook in one call: sheets; VBA modules, procedures, which can run here and which are blocked and why; event handlers; external objects (CreateObject) and Windows API (Declare) dependencies; project references; Power Query queries; data c
sheet_propose_editsPropose new contents for up to 20 cells (formulas like =SUM(B2:B9), or numbers/text). Nothing changes in the workbook: the engine previews the edits on the current revision and reports what would change and whether errors appear; the person decides whether to apply. Read the cell
sheet_applyApply a proposal from sheet_propose_edits to the workbook in this session's cabin (not to your original file); the engine recalculates. Refused if the workbook revision moved on since the proposal — propose again. Repeating an applied proposal is a no-op.
document_save_copyWrite the document or workbook as it is now in this session's cabin (after applied proposals) to a copy and return a download link valid for 24 hours. Your original file is never touched. A workbook with macros comes back as .xlsm with the VBA project intact; a document keeps its
document_export_pdfLay out the document as it is now in this session's cabin (after applied proposals, or as opened) and return a PDF download link valid for 24 hours, plus the page count. Documents only; for workbooks use document_save_copy.

Common questions
Is SumOffice — real Word and Excel for agents safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
Either way works: install it on your computer or connect to the cloud version.
Is it still maintained?
The GitHub repo last changed 22 days ago, and the latest version (0.3.1) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?

SumOffice MCP server — real Word and Excel for agents
One server, two ways to run it. The agent opens your .docx / .xlsx / .xlsm, reads it, proposes a change, you approve, the file comes back intact — Excel and Word open the result without a repair dialog. Macros (VBA) and Power Query travel with the file.
Registry name: com.sumoffice/office · page with proof: https://sumoffice.com/mcp · image: docker.io/hissih/sumoffice-mcp
Remote — nothing to install
https://view.sumoffice.com/mcp (streamable HTTP).
claude mcp add --transport http sumoffice https://view.sumoffice.com/mcpClients without HTTP support: npx -y mcp-remote https://view.sumoffice.com/mcp (see examples/).
Local over stdio — local file paths
docker run -i --rm -v "$PWD:/work" hissih/sumoffice-mcpThe server runs on your machine and accepts path in document_open_file (paths under /work). The file itself is opened in a private, short-lived editor session on the SumOffice server and deleted after the session; nothing in the file is executed.
Tools
| Documents (.docx) | Spreadsheets (.xlsx/.xlsm/.xlsb) | Both |
|---|---|---|
document_open_file, document_open, document_describe, document_read, document_find, document_comments, document_propose_replacement → document_apply | sheet_describe, sheet_read, sheet_find, sheet_propose_edits → sheet_apply, macro_list, macro_read_source, macro_plan, query_list, query_explain, workbook_inspect | document_save_copy, document_export_pdf |
propose_* never writes: it returns a diff for the person or the client to approve; *_apply applies exactly that proposal. Every step is listed in the response, so the agent cannot change a file silently.
Examples
examples/claude-desktop.json— Claude Desktop (claude_desktop_config.json), local stdio via Docker.examples/cursor-mcp.json— Cursor (.cursor/mcp.json), remote HTTP.examples/claude-code.sh— Claude Code, both variants.examples/docker-compose.yml— the local server as a compose service with a mounted folder.
What it does not do yet
- One editor session per document at a time; a second agent on the same file gets read-only.
- Power Query definitions are preserved, not refreshed, in the server session.
- Macros are read and routed (which will run natively, which stay in Excel); they are not executed by the MCP server.
Limits and privacy
Free, no account. Remote: per-address daily quota; files are deleted after the session or 24 hours at most, never used for anything else. Details: https://sumoffice.com/app-privacy.html
