SheetRelay

SheetRelay connects a Google Sheet once and gives each tab a REST address and MCP tools, so Claude, ChatGPT, or Cursor can read and write rows in conversation and your own site can do the same over plain HTTP. Read, add, change, and delete are separate switches per tab, masked columns never leave the server, and keys can be narrowed and revoked. Nothing is copied: rows are read from the sheet when a call asks. Free for 2 spreadsheets and 1,000 calls a month, paid plans from $9.
