A brain for your app, from Claude.
Add your docs, a PDF or a whole website. Your agent gets answers that cite their source, and says so when it does not know instead of making something up. No servers, no vector database, no keys to copy.
Claude Code: three steps
- Add MaBrain to Claude Code:
claude plugin marketplace add smtx/mabrain-plugin - Install it:
claude plugin install mabrain@mabrain - Open Claude Code, type
/mcp, pick mabrain and sign in with GitHub. Your brain is created right there.claude
Then just ask, in your own words: “Add https://example.com/docs to my brain”, “add this PDF”, “connect my agent to my brain”.

What it does
Learns your material
Files, single pages or a whole site. Pages are crawled on your machine and sent as they are: nothing is summarised on the way.
Answers with receipts
Every fact comes with its source and a certainty from 0 to 1, ready for your agent's prompt.
Knows what it doesn't know
Questions it cannot answer become gaps you can fill. You approve or reject facts, one at a time.
Price
free every month, to build your brain: about 100 web pages or a 400-page PDF.
for your agent to search the brain, as often as it likes.
You see what an upload will cost before it happens. All you need is a GitHub account.
