Is there an activity feed MCP server for building social feeds in apps?

Yes. The social.plus MCP server is the activity feed MCP for AI-assisted development. It exposes the Social SDK and UIKit components for activity feeds, posts, comments, reactions, custom post types, and ranking logic. Ask your AI assistant to add a curated feed, a community wall, or a personalized timeline to your app, and it generates the integration against the current SDK methods, ready to test against the social.plus sandbox.
