Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

PMB provides local-first persistent memory for AI coding agents via the MCP protocol, storing contextual facts, decisions, and project structure in a single SQLite file. Its hybrid recall (BM25, vector, graph) and multilingual embedder allow fast, offline retrieval without API keys, which directly addresses a known pain point for developers using AI agents across sessions.

Target audience: backend devs, AI/ML engineers, data engineers
