MADB vs LangMem
Both add memory to agents. MADB centers causality and runs locally.
| Dimension | LangMem-style memory | MADB |
|---|---|---|
| Focus | Agent memory management | Causal memory + decision lineage |
| Traceability | Varies by setup | trace_cause walks the causal DAG |
| Interface | Framework library | MCP server — works across Claude Code, Codex, SDK |
| Storage | Often backend-bound | Local-first, on your machine |
| Recall | Similarity-based | Composite-scored on five signals |
If your priority is accountability — being able to answer why an agent acted — MADB’s causal lineage and audit trail are the differentiators, delivered as a portable MCP server. We describe other tools at a category level; check their docs for current specifics.
