caldav-mcp vs mcp-gateway

Q: Which is better, caldav-mcp or mcp-gateway?

By GitHub stars, caldav-mcp has more community adoption, but the best choice depends on your specific use case.

caldav-mcp: CalDAV-MCP is a server implementing the Model Context Protocol, designed to expose standard CalDAV calendar operations such as listing, creating, updating, and deleting events and tasks. It allows AI assistants to interact with CalDAV servers, enabling intelligent scheduling and task management capabilities.; mcp-gateway: MCP Gateway enables AI assistants to securely access internal tools without exposing public endpoints, providing cryptographically secure, zero-trust connectivity. It aggregates multiple tool backends into a single secure endpoint, leveraging OpenZiti, zrok, and Agora for dark services that work through NATs and firewalls.
