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
