Minimal Notion-style workspace with a built-in MCP server.
A self-hosted document workspace: nested pages, a block editor, real-time collaboration, workspaces and invites, and public share links. It exposes its own MCP server, so Claude, ChatGPT, Gemini, Cursor and VS Code can search, read and write pages directly.
How it works
1
Collaboration without a realtime server
Documents are Yjs CRDTs. Clients append updates to a log in Postgres and poll adaptively (1.2s active, 30s hidden), trading a second of latency for zero realtime infrastructure.
2
Local-first editing
Pages render from IndexedDB before the network answers, and queued edits replay after a dropped connection.
3
MCP for your assistants
JSON-RPC over streamable HTTP with tools to list, search, read, create, update and share pages. Tokens are hashed at rest and revocable.
