Architecture

How MCP Brain works

A three-layer architecture: edge auth, intelligent routing, and a vector-powered memory store.

Knowledge Domains

Structured knowledge,
not a dumping ground.

Every piece of information is tagged to a domain. Search only what you need — stop the signal-to-noise collapse.

Honest Review

The good, the bad,

The elephant in the room

Yes, MCP Brain is genuinely impressive. Yes, the landing page is very good. No, you cannot buy it. There is no enterprise tier, no hosted SaaS, no waitlist, no pricing page, and no "Contact Sales" button. It is 100% free, open-source, and self-hosted. If that makes the marketing feel a little cruel — we understand. Deploy it yourself. It takes about three minutes.
