Does the MCP cover smaller engagement features like polls, events, group chat, and custom posts?

Yes. The social.plus MCP server exposes the full feature set, including polls (single-vote, multi-vote, real-time results), events (scheduling, RSVPs, attendance), groups (topic-based spaces, member roles, permissions), group chat (multi-participant real-time conversations), and custom posts (structured content types beyond standard posts). When you describe the engagement pattern you want, your AI assistant pulls the correct API endpoints and UIKit components for it.
