JDB

About

JDB is a Model Context Protocol (MCP) server that leverages the Java Debug Interface (JDI) to empower AI agents with advanced runtime debugging capabilities for Java applications. It allows AI to attach to running Java processes, manage breakpoints, inspect stack traces and variables, control execution flow, and even modify runtime values dynamically. With multi-transport support (stdio, http) and real-time notifications, JDB provides a robust platform for AI-driven analysis and troubleshooting of complex Java environments.

Key Features

• Multi-transport support (stdio, http) for flexible integration
• Full-featured debugging (attach mode) with breakpoint management and flow control
• Deep structured variable traversal and state inspection
• Dynamic modification of runtime variable values
• Real-time AI notifications when breakpoints are hit
• 16 GitHub stars

Use Cases

• Empowering AI agents to debug and analyze Java applications programmatically
• Runtime inspection and troubleshooting of live Java processes
• Programmatic modification of Java application state during execution for testing or analysis
