[ FAQ ]
Common questions
What does the Google Calendar MCP server do?
Google Calendar exposes list calendars and events, create update delete events, suggest meeting times to MCP-compatible AI clients. Bifrost connects to it as an upstream MCP client and exposes approved tools through one governed /mcp endpoint.
How does Google Calendar authenticate when used with Bifrost?
Google Calendar uses OAuth 2.0 (Google Cloud client). Store credentials in Bifrost's environment or credential configuration so they stay at the gateway instead of being copied into every AI client.
Can Claude Desktop, Cursor, or Claude Code use Google Calendar through Bifrost?
Yes. After registering Google Calendar in Bifrost, point any HTTP MCP-compatible client at the Bifrost /mcp endpoint and authenticate with a virtual key. The client sees only the tools allowed for that key.
