SheetRelay

SheetRelay: Data integration tool that turns a Google Sheet into an API and MCP server for code and AI assistants.

SheetRelay turns a Google Sheet into a live API and MCP server, allowing code and AI assistants to read and write spreadsheet data securely. Users connect a spreadsheet once, configure permissions per tab, and expose or hide specific columns as needed. AI assistants like Claude and ChatGPT can interact with the data in plain language, while custom code or web forms use standard REST endpoints. The system applies strict permission switches for reading, adding, changing, and deleting data, ensuring that hidden columns never leave the server. It suits developers, creators, and business users who need a lightweight backend or database connected directly to spreadsheets without duplicating data.
