Koskamo

agent-spreadsheet MCP

An MCP server that provides agent-safe Excel workbook analysis, editing, recalculation, and verification tools. It allows LLM agents to read, analyze, mutate, verify, and operationalize Excel workbooks (.xlsx, .xlsm, .xls, .xlsb) using a token-efficient interface powered by the Formualizer engine, avoiding brittle UI automation.
