SignUpGenius MCP

An MCP server for SignUpGenius that provides tools for managing sign-ups, slots, groups, and RSVPs. It supports reading public sign-up details and slots without credentials, while write operations like claiming slots or adding group members require authentication via Pro API key, session login, or a browser extension fallback.
