This is a small library for giving an agent persistent memory without running any infrastructure. The whole store is one SQLite file, and the default install has no dependencies. I built it because whenever I wanted an agent to remember a handful of facts across sessions, the options were a hosted API, a vector database, or a framework, and that felt like too much for what is usually a few thousand short strings.The part I find most useful is that recall is deterministic, so you can write unit tests that assert what your agent remembers and run them in CI. I haven't seen that elsewhere and it's what I rely on most. Beyond that: it's one file you can copy, inspect, or delete, with no server or background process; every result can show its own score breakdown, so ranking isn't a black box; and every change is journaled, so you can snapshot the store and diff it later. It also exposes an MCP server, so an MCP-capable agent like Claude can use it directly, and there are LangChain and CrewA...
