Stash
Stash is an open-source persistent memory layer for AI agents that turns raw interactions into structured long-term knowledge. It stores episodes, facts, relationships, causal links, goals, failure patterns and confidence-decayed insights in Postgres with pgvector, then exposes memory through an MCP server compatible with Claude Desktop, Cursor, Windsurf, Cline, Continue, OpenAI Agents, Ollama and OpenRouter-based workflows. Stash is for developers who want agents that remember across sessions without relying on opaque hosted memory features. It helps teams preserve context, reduce repeated explanations and build more personalized assistants. The project is notable now because it packages a deeper consolidation pipeline into a self-hosted single-binary style tool at a time when agent memory is becoming a core infrastructure layer.
