Second Brain is a self-hosted MCP server on Cloudflare Workers that provides a persistent memory layer for AI tools like Claude, ChatGPT, and Cursor. It allows storing, searching, and recalling information across conversations with semantic search and recency bias. Deployable with one click on Cloudflare's free tier.

second-brain-cloudflare sits in the Memory & Context category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Store anything with `remember`. A representative use case is Give Claude a persistent memory across sessions. The listed license is MIT. GitHub stars are currently 818. Relevant tags include ai-memory, claude.
