Pros & cons
claude-mem
Pros: OSS plugin that adds auto-memory + indexing without sending data to Anthropic's cloud — strongest privacy posture for Claude Code memory.
Cons: Plugin install + maintenance burden; less polished than first-party auto-memory.
Official MCP Memory server
Pros: Reference implementation in the MCP spec; smallest possible memory primitive — useful for testing and lightweight cases.
Cons: Minimal feature set — no extraction, no governance, no retention policy; production deployments quickly outgrow it.
