## Description

Lumen JFR Forensics is a hybrid TypeScript/Java server that parses JVM Flight Recorder data to give AI agents deep diagnostic capabilities for Java application incidents. It provides six analysis tools covering exception forensics with full call chains, JDBC slow query detection with source line attribution, socket latency analysis, CPU hotspot profiling, GC health and allocation analysis, and thread lock contention identification. The TypeScript bridge handles MCP protocol communication while the Java engine performs high-performance JFR parsing.
