Operator: Andrey Ivanov (personal). Application: Andrey Sheets MCP. Contact: andreyefffivanov@gmail.com.

What this service is

Andrey Sheets MCP is a personal Model Context Protocol (MCP) bridge that lets the operator’s AI tools read and write Google Spreadsheets belonging to the operator’s Google account.

Data we process

• OAuth tokens (Google OAuth client id/secret and refresh/access tokens) stored as encrypted environment secrets on Cloudflare Workers/Pages — not in client browsers or public repositories.
• Spreadsheet contents requested by the MCP client (cell values, ranges, spreadsheet metadata) — processed in memory only to fulfill the API request and returned to the authenticated MCP caller. We do not sell or retain spreadsheet contents as a product dataset.
• Technical logs may include timestamps, request path (with secret redacted), status codes, and error classes. Logs must not include OAuth secrets, refresh tokens, or cell contents.

Purpose

Data is processed solely to provide a personal Sheets MCP for the operator: authenticate to Google Sheets/Drive APIs and execute read/write tool calls initiated by the operator’s MCP client.

Sharing

We do not sell personal data. Spreadsheet data and tokens are not shared with third parties except Google (as the API provider when fulfilling requests) and the infrastructure host (Cloudflare) as a processor for running the Worker. No advertising partners.

Storage and retention

OAuth credentials live in Worker/Pages secrets until the operator rotates or deletes them. Spreadsheet payloads are not stored persistently by the app beyond transient request handling. Infrastructure logs follow the host’s retention defaults and should be minimized.

How to remove access

1. Google Account → Security → Third-party access with account access → remove Andrey Sheets MCP / the OAuth client.
2. Delete or rotate Worker secrets (GOOGLE_REFRESH_TOKEN, MCP_PATH_SECRET, client credentials).
3. Optionally disable or delete the Cloudflare Pages project.
