sheets.fast: spreadsheets for software agents

Field notes

The service creates a workbook through a POST request and returns both an identifier and a browser URL, allowing agents or scheduled jobs to update the same grid over time. The homepage says its MCP tool set uses about 1,860 tokens across eight tools, compared with 13k–17k for unnamed comparable connectors. It also displays a 43/43 evaluation result and links to a public scoreboard, though those performance figures remain site-stated claims.
