Governing AI Agent Decisions with MCP: How I Built Dead Letter Oracle
python
dev.to
Dead Letter Oracle turns failed events into governed replay decisions. The Problem Nobody Solves A failed message hits the DLQ. The fix looks obvious. The replay still breaks production. Every on-call engineer who has manually replayed a DLQ message and watched it break production again knows this problem. In event-driven systems, messages fail silently. They land in a dead-letter queue with a vague error and an angry on-call engineer staring at them. The diagnosis is manual.
