Personal Google Sheets MCP

Streamable HTTP MCP connector for Google Sheets (personal / non-commercial use).

This Worker exposes an MCP (Model Context Protocol) endpoint that lets compatible clients (e.g. Cursor / Grok Custom MCP) read and write spreadsheets via the Google Sheets API v4 on your behalf.

Endpoint

MCP URL shape: /mcp/<your-path-secret>

The path secret is configured as Worker secret MCP_PATH_SECRET. Wrong or missing secret → HTTP 401.

Tools

get_spreadsheet
get_values
update_values
append_values
clear_values

Auth model

MCP clients authenticate only with the path secret. Google API access uses OAuth2 refresh token stored in Worker secrets (scopes: spreadsheets + drive.file).
