Common questions

Is SumOffice — real Word and Excel for agents safe?

It passed 1 of 1 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 –, 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 in developer mode.

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/mcp

Clients 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-mcp

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.

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

Licence

This repository (documentation, manifest, examples) is MIT. The server image is free for evaluation and for use with the public endpoint; production use inside an organisation is licensed per application — https://sumoffice.com/download#server. Questions: hello@sumoffice.com
