AI Agents & Assistants

Perseus is a memory and context layer for AI agents that delivers only the needed live workspace facts, reducing prompt tokens by up to 94%.

Python Latest v1.0.24 · 10d ago Security brief →

Features

  • Live context engine that resolves current workspace state into verified facts before an agent’s call
  • Zero‑orientation scaffolding – one command (`perseus quickstart`) creates a ready‑to‑render `.perseus/context.md`
  • Durable, encrypted persistent memory via the companion Perseus Vault (MCP server with SQLite + FTS5 and built‑in embeddings)
  • Supports continuous updates with `perseus watch`, cron, systemd, or launchd to keep context live
  • Integrates natively with MCP‑compatible assistants (Hermes, Claude Desktop, Cursor) via simple config entries
