Coding agents guess because they don't know what you know. Feed them your Constella library and Claude Code, Codex, and every assistant becomes actually useful — working from your real memories, not generic web pulls.
Setup instructions
Constella exposes your library as an MCP server. Point any compatible agent at the endpoint with your personal key and it can search, recall, and reason over everything you've saved.
Find your personal API key in the Constella desktop app — open the “Upgrade Your Assistant” card at the bottom of the dashboard sidebar, or Settings. Replace YOUR_CONSTELLA_API_KEY in the snippets below with it. Get the desktop app →
npm install -g @anthropic-ai/claude-codeclaude/mcp — you should see constella ✓ connected.Build your second brain in Constella, then connect it once. Your agents stop guessing and start working from what you actually know.
