A hosted Google Workspace MCP server that skips the usual OAuth setup dance. Instead of creating your own Google Cloud project and managing credentials, you authenticate once through their web interface and get an API key. Connects to Calendar (list events, check availability, create/update/delete) and Sheets (read/write ranges, append rows, semantic search over data). Uses proxy OAuth with encrypted token storage, so your MCP client just needs the API key in a Bearer header. The drive.file scope means you explicitly pick which spreadsheets to grant access to during auth. Open source and self-hostable on Cloudflare Workers if you want to run your own instance.
