Archetypal AI

Persistent memory for AI agents with recall, remember, and checkpoint tools that preserve context across Claude Code sessions.

Provides persistent memory for AI agents through three core tools: recall restores previous session context, remember inscribes facts into permanent storage, and checkpoint preserves full agent state before shutdown. The server runs on Cloudflare Workers with Durable Objects for storage, accessible both as a stdio MCP server via npm and as a hosted remote endpoint. Memory persists across sessions with no account or API key required.
