Summary
Connects Claude and other AI assistants directly to JProfiler's profiling engine via MCP. Exposes CPU hotspot analysis, memory allocation tracking, JDBC query profiling, and HTTP call inspection as tools your agent can invoke during development sessions. You'd reach for this when debugging performance issues in Java applications and want your AI assistant to analyze profiler snapshots, identify bottlenecks, and suggest optimizations without leaving the conversation. Requires a JProfiler license (10-day trial available). Supports optional filters to limit which profiling subsystems are exposed and configurable call tree depth for managing response size.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
