SelfMem: One Memory Layer Across Every AI Assistant — Free & Open MCP Tool

SelfMem is one of the most useful MCP tools I've tested this year — and it's free, open-source, and self-hostable.

Why SelfMem Matters for DevOps/SRE Teams

If you run multiple AI coding assistants (Claude, Cursor, Windsurf, etc.), you've probably dealt with context fragmentation — each tool has its own memory, none of them talk to each other. SelfMem solves this with an MCP-native memory server that all your AI assistants share.

Key Features

  • Hybrid Search: PostgreSQL full-text search + pgvector semantic search — you get keyword precision AND semantic understanding in one query
  • 9 MCP Tools: create, search, update, delete, tag, bookmark, and more — all exposed as standard MCP tools
  • Self-Hostable: Docker one-liner. No vendor lock-in. Your data stays on your infrastructure.
  • Free Tier: No credit card required. Generous free tier for individual developers and small teams.

How It Compares

I've tested Mem0, ChromaDB, and a few other memory solutions for AI agents. SelfMem wins on simplicity, search quality (hybrid FTS + vector beats pure-vector), MCP-native design, and zero recurring cost for small teams.

If you're building AI-assisted DevOps workflows, this is worth 10 minutes of your time to spin up.
