OpenWorkbook - Automate Excel without expensive AI seats.

OpenWorkbook is a local-first MCP runtime for live spreadsheet automation, starting with desktop Excel. It helps teams bring AI agents to real office workflows without requiring every user to depend on expensive frontier-model subscriptions. Agents get compact workbook context and safe workflows for previews, validation, backups, rollback, formulas, styles, tables, and template-aware edits, with flexibility across MCP-capable clients and open-weight models.
