SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill allows AI agents to perform deep runtime debugging of Java applications, simplifying complex debugging scenarios.

Core Features & Use Cases

  • Multi-transport Support: Connect via stdio or http for debugging ease.
  • Full-featured Debugging: Supports attach mode with breakpoint management, flow control, state inspection, and dynamic modification.
  • Simplified Design: Single-session debugging reduces complexity and minimizes management.
  • Real-time Awareness: Leverages MCP Notifications for immediate breakpoint hits.
  • Use Case: Debug a SpringBoot application efficiently, inspecting and modifying variables and threads in real-time.

Quick Start

To start debugging, run the command 'jdb-mcp --transport stdio'.

Frequently Asked Questions about jdb-mcp-java-debugger

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug a running Java application using an AI agent?▼

You can debug a running Java application by attaching an AI agent to the process via the Model Context Protocol. This enables comprehensive runtime analysis including breakpoint management, thread inspection, and variable modification.

What is the best way to inspect and modify Java variables in real-time?▼

Inspecting and modifying Java variables in real-time is achieved by attaching to a running process through the Model Context Protocol. This allows dynamic state inspection and modification during execution.

How do I set up a Java debugging server for AI integration?▼

To set up a Java debugging server for AI integration, run the command 'jdb-mcp --transport stdio'. You can also use the http transport to connect your AI agent for runtime analysis.

Does MCP support real-time breakpoint notifications for Java debugging?▼

Yes, MCP supports real-time breakpoint notifications for Java debugging. It leverages MCP Notifications to provide immediate awareness when breakpoints are hit during execution.

Can I use this Java debugger for a SpringBoot application?▼

Yes, you can debug a SpringBoot application efficiently by attaching to the running process. This allows you to inspect and modify variables and threads in real-time within a single-session design.

What are the limitations of single-session Java debugging?▼

Single-session Java debugging reduces complexity by supporting only one active debugging session at a time. This minimizes management overhead but means you cannot concurrently debug multiple separate Java processes within the same server instance.
