Perseus Vault Overview

Perseus-Computing-LLC/perseus-vault MCP server gives AI agents durable local memory through a Rust binary backed by SQLite. It exposes memory operations over MCP, combining BM25-style full-text search, dense-vector retrieval, and reciprocal-rank fusion for recall. Data can remain offline in one database file, with AES-256-GCM encryption enabled by default for new installations. Reach for it when agents need persistent context across sessions without a cloud dependency.
