●●●BangerBig BrainSolve My ProblemZero to One

MCP server for spreadsheets when every other AI tool sends your data to the cloud.

Strengths

•Non-destructive derivations allow branches, views, and snapshots without mutating master data
•Any MCP-aware agent like Claude Code or Cursor can query spreadsheets as native tools
•MIT licensed open source with npx install in under 60 seconds

Weaknesses

•MCP ecosystem still emerging—limited agent support beyond Claude Code and Cursor
•Google Sheets private access requires OAuth setup that adds friction to first run

I created iHateCSV.com for those who hate it when spreadsheets break

Everything runs in the browser — CSV↔XLSX converters, PDF table extraction, encoding fixes and AI-powered cleaning — which is an actual differentiator for privacy-conscious users. The claim of processing millions of rows client-side hints at WASM/WebWorker engineering rather than a cosmetic UI; that technical promise is exciting, though the site doesn't show limits (memory, streaming, reproducibility) or integrations yet.
