Marrow
The judgment layer for AI agent fleets
Marrow is the judgment layer for AI agent fleets. While memory tools struggle with junk data, Marrow focuses on decision intelligence and governance. Key Features: • Workflow Enforcement: Blocks agents that skip steps (HTTP 409). • Drift Rate Monitoring: Alerts when agents deviate from defined processes. • Cryptographic Audit Trail: Tamper-proof logs for compliance. • Collective Intelligence: Learn from fleet patterns without data leaks.
While memory tools (mem0, Letta) help agents remember, they don't stop them from making bad decisions. We found that up to 97% of agent memory can be junk data.
Marrow sits above memory as the judgment layer:
✅ Enforces workflows (blocks invalid steps)
✅ Monitors drift rate & loops
✅ Cryptographic audit trails
Open source SDK/MCP + Free tier available.
