Real Word and Excel for agents: open your .docx/.xlsm, read, propose, apply, get it back intact.
Lets an assistant open real Word and Excel files, read them, propose edits for approval, and return an intact copy or PDF.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.sumoffice%2Foffice/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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.

https://view.sumoffice.com/mcp (streamable HTTP).
Clients without HTTP support: npx -y mcp-remote https://view.sumoffice.com/mcp (see examples/).
The 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.
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.

Open a demo document or workbook
Open 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 own file use document_open_file. Opens a separate editor cabin for this session.
slugrequiredOpen your own Word document or Excel workbook
Open 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 file is executed. The file is kept for 24 hours and then deleted. After opening, use document_* tools for a document or sheet_* / macro_* / query_* / workbook_inspect for a workbook; sheet_propose_edits → sheet_apply and document_propose_replacement → document_apply change the copy in the cabin; document_save_copy returns a download link of the edited file.
urlnamepathbase64What the document is
Name, pages, paragraphs, words, number of comments and tracked changes, whether track changes is on. For documents; call first.
Takes no parameters.
Read paragraphs
Paragraph 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.
fromrequiredcountFind in the document
Paragraphs containing the text (case-insensitive), with snippets around the match.
queryrequiredComments and tracked changes
Comments (author, text, anchor, resolved) and tracked changes — up to 50.
Takes no parameters.
Propose replacing one paragraph's text
Propose 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 first.
textrequiredreasonparagraph_indexrequiredApply a proposed paragraph replacement
Apply 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.
proposal_idrequiredWorkbook 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.
Takes no parameters.
Read 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 quietly be about the wrong sheet. Call sheet_describe first if you do not know the tab names.
rangerequiredsheetFind 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.
queryrequiredsheetList VBA modules and runnable macros (entry points) in this workbook with their route and blockers. Runs nothing.
Takes no parameters.
Read the source text of one procedure (module + procedure name from macro_list). Read-only; runs nothing.
modulerequiredprocedurerequiredPlan a macro run without running it: route, whether the engine can run it natively, blockers, instruction budget.
entrypointrequiredactive_sheetList Power Query queries in this workbook: names, step chain, load target, connections. Reads only; refreshes nothing.
Takes no parameters.
Explain one Power Query query by name: its steps in order, where it loads, its connection. Reads only; refreshes nothing.
namerequiredMap 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 connections; form controls, ActiveX, embedded objects (preserved). Runs nothing. Call this first for questions like 'how is this workbook built' or 'what does it depend on'.
Takes no parameters.
Propose 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 cells first. Do not overwrite input numbers unless the task says so. Then call sheet_apply with the proposal_id.
editsrequiredsheetreasonApply proposed cell edits
Apply 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.
proposal_idrequiredSave a copy of the edited file
Write 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 styles, comments and tracked changes.
inlineRender the document to PDF
Lay 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.
Takes no parameters.
100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
