Stash AI Memory

Skill by ara.so — Daily 2026 Skills collection.

Stash is a self-hosted persistent memory layer for AI agents. It stores episodes, facts, and working context in Postgres with pgvector, runs an 8-stage consolidation pipeline to turn raw observations into structured knowledge, and exposes everything via an MCP server that works with any MCP-compatible agent (Claude Desktop, Cursor, Windsurf, Cline, Continue, OpenAI Agents, Ollama, OpenRouter).
