hissih/sumoffice-mcp repository overview

⁠SumOffice MCP server (stdio)

The same MCP server that runs at https://view.sumoffice.com/mcp, started on your machine so an agent can pass local file paths. The file itself is opened in a private editor cabin on the SumOffice server; your original is never modified; the edited copy comes back as a 24-hour link; uploaded files are deleted after 24 hours.

⁠Run

{ "mcpServers": { "sumoffice": {
  "command": "docker",
  "args": ["run", "-i", "--rm", "-v", "/path/to/files:/work", "hissih/sumoffice-mcp"]
} } }

Then document_open_file with path: "/work/report.xlsm" (or url / base64 as with the remote server).

⁠Tools

• Open: document_open_file (.docx .doc .odt .xlsx .xlsm .xlsb .xls .ods, up to 50 MB), document_open (demo files)
• Workbook: sheet_describe, sheet_read, sheet_find, macro_list, macro_read_source, macro_plan, query_list, query_explain, workbook_inspect
• Document: document_describe, document_read, document_find, document_comments
• Change: sheet_propose_edits → sheet_apply; document_propose_replacement → document_apply (previewed by the engine first; stale proposals are refused)
• Back: document_save_copy (a macro workbook returns as .xlsm with the VBA project untouched), document_export_pdf

Proof, tool table and the remote endpoint: https://sumoffice.com/mcp⁠ — Registry name: com.sumoffice/office. No account, free. Nothing in a file is executed.
