Thread Dump Analyzer (TDA)
A Java thread dump and heap analysis tool that runs as a GUI application, VisualVM plugin, or headless MCP server, enabling AI agents to parse thread dumps, detect deadlocks, identify long-running threads, and analyze virtual thread pinning.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Community/specialized tool. Apply standard security practices for category. Review documentation for specific security requirements.
⚡ Reliability
Best When
You have a JVM performance incident (deadlock, thread starvation, memory pressure) and want an AI agent to help analyze thread dump artifacts to diagnose root cause.
Avoid When
You need real-time continuous monitoring rather than snapshot analysis, or your issue is not JVM-related.
Use Cases
- • AI-assisted JVM performance debugging by having agents analyze thread dumps for bottlenecks
- • Automated deadlock detection in production Java applications via MCP integration
- • Virtual thread pinning analysis for Java 21+ applications migrating to Project Loom
- • Heap class histogram analysis to identify memory pressure from object allocation patterns
- • Long-running thread identification across multiple sequential thread dumps
Not For
- • Non-JVM languages or runtimes
- • Real-time APM or continuous production monitoring (point-in-time analysis only)
- • Teams that need integrated profiling with CPU flame graphs
Interface
Authentication
No authentication required. Runs locally as a headless MCP server via stdio.
Pricing
LGPL-2.1 licensed. Free to use.
Agent Metadata
Known Gotchas
- ⚠ Must be launched with -Djava.awt.headless=true flag for MCP mode or GUI will attempt to open
- ⚠ JSON thread dump support (Java 21+) is experimental with documented limitations
- ⚠ Requires Java 11+ runtime to execute the server
- ⚠ MCP server is a secondary use case for a primarily GUI tool - may have rough edges
