Lesson preview

MCP (Model Context Protocol) is the standard that lets your assistant (the client) plug into a tool (the server) — Notion, Gmail, Drive — and actually read and act on your real data. The skill isn't connecting everything at once; it's connecting one high-frequency tool, walking a read → cross-tool read → gated write ladder, and auditing permissions like you mean it. Model Context Protocol is a standard, not a product — it defines how an AI assistant (the client) talks to a tool (the server) so the assistant can see and act on real data instead of just chatting about it in the abstract. Your chat client — Claude, ChatGPT, or another assistant — is always the client in this relationship; the server is the plug on the tool's side, whether that's Notion, Gmail, Drive, or a niche SaaS product. Think of it like USB for AI: before a shared standard, every tool needed a custom, one-off integration. MCP means any compliant client can talk to any compliant server, which is why connectors have exploded in the last year. But a standard plug doesn't mean every socket is safe — that's still on you. Resist the urge to connect everything you use. The right first connector is whichever tool you touch most often, because that's where a small daily improvement compounds fastest — for most people that's Notion, Gmail, or Drive. One connector, mastered and audited, beats five connectors half-understood. Every connection you add expands your surface area: more permissions to track, more prompt-injection exposure (a malicious document or email the assistant reads could try to smuggle in instructions), and more mental overhead figuring out what the assistant can and can't do. The ladder, not the buffet.
