Second Brain Cloudflare

Second Brain Cloudflare is a TypeScript application that stores personal and team knowledge in a Cloudflare Worker and makes it available to MCP-compatible AI tools. It supports capture, organization and semantic recall through a shared memory layer, with REST and MCP connections.

Practical overview

When it fits

Use it when context is scattered across AI tools and you want a persistent memory store that those clients can query. Team Edition fits workflows that need both private personal knowledge and a shared layer with explicit sharing controls.

Who it is for

  • People who want project context, decisions and preferences available across multiple AI assistants.
  • Teams that need private individual memories alongside a deliberately shared knowledge layer.
  • Developers seeking an MIT-licensed foundation for an MCP-connected memory service on Cloudflare.

Documented uses

  • Save a decision, preference, project update or note once and retrieve it later from another connected client.
  • Search saved knowledge using natural-language questions rather than exact wording.
  • Keep personal memories private while selectively sharing canonical memories with a team.
  • Review due items and open commitments associated with stored memories.
Before you choose

Requirements & limits

The README documents a desktop app for Mac and Windows and deployment to a user’s Cloudflare account. It describes the Cloudflare free tier; no price or account requirements for the primary service action are specified here.

  • The Worker uses Cloudflare D1, Vectorize, Workers AI and KV.
  • Clients connect by REST or MCP, and all connected clients use the same Worker.
  • Capture and keyword recall continue if Vectorize is unavailable, while semantic indexing is restored.
  • The shipped embedding models read English best; the desktop app can switch a brain to a multilingual reading.
  • Team Edition documents one shared team per brain, with personal memories private by default and deliberate sharing.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
