Excel MCP Server — Edit .xlsx Without Excel

Main

• Use stdio transport when your client runs on the same machine; switch to streamable HTTP for remote agents.
• Treat file paths as an allowlist: point the server at a dedicated workbook directory (README shows env vars like EXCEL_FILES_PATH).
• Prefer deterministic edits: describe the sheet layout first, then apply edits via tools instead of rewriting whole workbooks.

Source-backed notes

• README states it manipulates Excel files without requiring Microsoft Excel installed.
• README shows uvx excel-mcp-server stdio plus sse and streamable-http options, with /mcp as the streamable endpoint.
• README lists Excel features such as formulas, formatting, charts, and pivot tables.

FAQ

• Do I need Excel installed?: No—README explicitly says it works without Microsoft Excel.
• Which transport is best?: Use stdio for local; use streamable HTTP for remote access and stable URLs.
• How do I keep it safe?: Restrict the directory you expose and avoid running it with broad filesystem permissions.
