If you're building agents that need to remember things across sessions and tools, this gives you a full CRUD layer over Maindex's memory infrastructure. You get collections, typed memories with metadata, links between facts, semantic search, and bulk operations all through MCP. It connects to their hosted graph at expert.maindex.io, which means your agent's memories sync across Claude, Cursor, ChatGPT, or whatever else you hook up via their OAuth flow. Useful when you want structured, traceable memory instead of dumping context into a vector DB or rewriting the same facts into every chat. The Expert tier exposes the full API, including collection locking and revision history.
