Connects Claude to SignUpGenius for managing volunteer signups, event slots, and groups. Supports three auth modes: Pro API key (required for slot reports showing filled/available participants), direct email/password login (works with free accounts), or cookie passthrough via the fetchproxy extension for zero-config setup. Exposes 13 read tools and 1 write across profiles, groups, signup lists (created/invited/signed-up-for), and participant reports. The session mode hits the same internal API the dashboard uses, so treat this as personal automation for your own account. If you coordinate volunteers through SignUpGenius and want Claude to check signup status, pull rosters, or add group members without opening a browser, this is the bridge.
