A documentation workspace where an agent writes the docs and a human keeps editing them. Next.js 15 and Nextra 4 render the site; a BlockNote editor persists every page to Postgres; and an MCP server lets Claude document a codebase straight into the workspace — point it at a repository, approve the page tree, and the pages land where they stay editable in the browser.
Claude connects over OAuth 2.1 with dynamic client registration — no key to paste. The client discovers the authorization server from an unauthenticated 401, registers itself, and the token it receives is scoped to the workspaces that user belongs to and nothing else.
Docs are updated one section at a time: `getPageOutline` for the block id, then `updatePageSection`. The call never carries the rest of the document, so an edit cannot silently drop a paragraph it was not asked about.
`updatePageSection` refuses with a conflict rather than reverting a page that moved between the read and the write — the agent is told to re-read instead of overwriting a human edit.
BlockNote in two forms — embeddable in MDX pages, and persisted to Postgres under `/projects`. Every page has read-only version restore points, and the page tree lives in the layout so it survives navigation.
Every connected client is listed under Settings → MCP access, named after the client. Revoking one is a click and stops that client immediately without touching the others; headless clients get a personal access token from the same panel.
