About mcp-server-spreadsheet

marekrost/mcp-server-spreadsheet

Data-first MCP server for reading and writing spreadsheet files (.xlsx, .csv, .ods) - cell-level ops + DuckDB SQL engine

Implements MCP (Model Context Protocol) as stdio transport to integrate with Claude Desktop and Claude Code, enabling AI assistants to perform spreadsheet operations. Combines cell-level workbook manipulation (insert/delete rows, copy ranges across sheets) with in-memory DuckDB SQL queries that support JOINs and mutations written back to disk. Uses stateless, explicit file/sheet parameters with atomic temp-file writes and automatic type coercion, treating CSV as single-sheet workbooks while preserving native typing across Excel and OpenDocument formats.
