MCP: Cerebro - Brein

Cerebro tools let an AI client read the team’s commercial context before it acts and update that context when the team has a durable decision to keep. Read MCP and OAuth first for authentication and workspace permissions.

Read context

Tool	Use it when you want to…	Main arguments
`context_retrieve`	Find the most relevant context for a task or set of files.	`task`, `files`, `view`, `limit`
`context_get`	Read one document in full.	`topic`, `view`

context_retrieve returns a short result by default. Fetch the full document only when you need it.

Update context

Tool	Use it when you want to…	Main arguments
`context_create`	Create a document for a new durable decision.	`title`, `content`, `area`
`context_update`	Update an existing document.	`topic`, fields

Documents are shared with the workspace by default. A write does not delete another document or publish a page to the web.

Keep the context useful

A good Brein document explains:

what the team sells;
who the team wants to work with;
what is out of scope;
which geography and messages matter;
what the team decided and why.
