Perseus Vault — Persistent Memory for Claude (formerly Mimir/Mneme)

Perseus Vault (formerly "Mimir", then "Mneme") gives Claude durable memory across sessions. It is a single Rust binary (~8MB) with an embedded SQLite database — no Docker, no Postgres, no cloud. Features include: - 57 MCP tools for entity storage, hybrid search (FTS5 + dense vector), knowledge-graph traversal, journal audit trail, and state management - AES-256-GCM encryption at rest (optional, transparent) - Fully local — never phones home, no telemetry, air-gapped by default - Agent-first design — entity lifecycle with Ebbinghaus decay, auto-promotion, archiving - Works with any MCP host — Claude Desktop, Claude Code, Cursor, Hermes Agent, Perseus, and more Install in one line: curl -sSf https://raw.githubusercontent.com/Perseus-Computing-LLC/perseus-vault/main/scripts/install.sh | sh
