MAI Second Brain

MAI is the agent-first second brain: notes built for an AI to read, not just a human. Most note apps were built for a human reader and bolted an AI on later — MAI is built the other way round. You fill it by voice on iPhone, Apple Watch or Mac, an AI notetaker covers your meetings, and everything you capture is structured so an agent can search it, cite it and write back to it. This MCP server is the front door, and the MAI Second Brain plugin adds guided starter skills on top of it. Connected, Claude answers from your own words instead of like a stranger: "What did I decide about pricing?", "Summarize yesterday's meeting", "What should I focus on today?" It writes back carefully too — decisions become notes, commitments become tasks on today's list, follow-ups append to existing notes. 20 agent-ready tools, every one scoped to your account: hybrid keyword and semantic search, meeting transcripts, tasks, projects, recurring themes and your daily Focus Brief. Writes are additive by design — no delete tool exists, so notes can grow from a conversation but can't be lost to one. Six built-in prompts turn common rituals into one command: map my brain, save to brain, daily brief, weekly review, daily review and meeting prep. Connecting takes a minute: sign in with your MAI account email and a one-time code — no password, no API key. Requires an active MAI plan.
