PasteSheet converts a Google Sheet URL into a live, edge-cached REST API endpoint without requiring a Google Cloud project, OAuth setup, or any backend code. Each endpoint supports filtering, sorting, pagination, and full-text search via plain URL parameters. Every endpoint also functions as a Model Context Protocol server, allowing AI agents like Claude, Cursor, and ChatGPT to query spreadsheet data as a native read-only tool. PasteSheet is read-only by design, so agents can retrieve data but cannot modify the source sheet. A free tier supports up to three endpoints and 2,000 requests per month, with paid plans scaling from there.
