second-brain
ossA universal memory layer for AI coding agents. Ingests conversation history from Claude Code, Cursor, and other tools into a graph-backed knowledge store with vector search, then serves it via MCP so any AI agent can recall what you've discussed, decided, and built across projects and machines.
Every AI coding tool keeps its own conversation history locked in its own format. Claude Code stores JSONL in ~/.claude/projects/, Cursor keeps JSONL in ~/.cursor/projects/. None of them talk to each other, and none of them let you search across sessions. If you discussed an architecture decision with Claude last week and ask Cursor about it today, you start from zero.
second-brain fixes this by creating a single knowledge graph that ingests from all your AI tools, embeds everything for semantic search, tracks relationships between memories (reinforces, contradicts, supersedes), and exposes it all through MCP so any connected agent can recall context from any previous conversation.
