Description
From the marketplace listing
JDB (Java Debugger) plugin for Claude Code. Attach to running JVMs via JDWP and debug interactively with breakpoints, watchpoints, exception breakpoints, stepping, expression evaluation, thread inspection, stack navigation, and class introspection. ### Features - **Connect & Launch**: Attach to any JVM started with JDWP, or launch one directly with `jdb_launch` - **Multi-session**: Debug multiple JVMs simultaneously on different ports - **Breakpoints & Watchpoints**: Line/method breakpoints, field watchpoints, exception breakpoints with caught/uncaught filtering - **Execution Control**: Step in, step over, step out, continue, suspend/resume threads - **Inspection**: Evaluate expressions, dump objects, view locals, list loaded classes/methods/fields - **Stack Navigation**: Walk the call stack, move up/down frames, pop/re-enter frames - **Concurrency**: Thread listing, lock/monitor inspection for deadlock analysis - **Tracing & Monitoring**: Trace method entries/exits, auto-execute commands on each stop - **JDK Compatibility**: Supports JDK 8+ with feature detection (virtual threads on JDK 20+, thread-scoped breakpoints on JDK 13+) ### Prerequisites - Python 3.10+ - A JDK installation (for the `jdb` executable) ### Installation pip install karellen-jdb-mcp
