OpenBSP MCP for Google Workspace

What is this?

This is a hosted MCP server that connects AI assistants (like Claude) to your Google Calendar and Google Sheets. Once connected, you can ask your AI to check your schedule, create events, read spreadsheets, and more.

How it works

1. You authenticate with Google and grant permissions for Calendar and/or Sheets

2. You receive an API key to configure your MCP client

3. Your AI assistant can now access your Google data through our server
