Mimir — Persistent Memory (MCP)
Mimir is the persistent memory backend for Perseus — a lightweight Rust MCP server with SQLite + FTS5. Zero network calls, no API keys. As of v2.7.0, offline dense/hybrid embeddings are bundled by default (the model is compiled into the binary), so semantic recall works zero-config with no external model download. v2.12.0 provides 48 MCP tools across structured entities, hybrid vector search, RAG, connectors, confidence decay, journal events, and state management: mimir_remember, mimir_recall, mimir_context, mimir_traverse, mimir_decay, mimir_stats, mimir_health, and more.
