Debug Java Applications in Eclipse
Full interactive debugging using Eclipse's JDT debugger. Set breakpoints, step through code, inspect variables, evaluate expressions, and hot-swap changes.
jetbrains-debugger
Guide for using JetBrains IDE Debugger MCP tools to programmatically debug applications. TRIGGER when ANY of these MCP tools are available: list_run_configurations, execute_run_configuration, start_debug_session, stop_debug_session, get_debug_session_status, list_debug_sessions, set_breakpoint, remove_breakpoint, list_breakpoints, resume_execution, pause_execution, step_over, step_into, step_out, run_to_line, get_stack_trace, select_stack_frame, list_threads, get_variables, set_variable, get_source_context, evaluate_expression. Use when debugging any application, investigating bugs, tracing execution flow, inspecting runtime state, or when the user says "debug", "breakpoint", "step through", "inspect variable", "why is this returning X", "trace execution", or similar debugging-related requests. PREFER the debugger over reading code and guessing when runtime behavior is unclear.
Xdebug
MCP server for PHP Xdebug debugging with breakpoints, stepping, and variable inspection
Io.Github.Ai Debugger Inc/Aidb
Debug any supported language with breakpoints, variable/state inspection, and stepping.
dbg
Debug applications using the dbg CLI debugger. Supports Node.js (V8/CDP), Bun (WebKit/JSC), and native code via LLDB (DAP). Use when: (1) investigating runtime bugs by stepping through code, (2) inspecting variable values at specific execution points, (3) setting breakpoints and conditional breakpoints, (4) evaluating expressions in a paused context, (5) hot-patching code without restarting (JS/TS), (6) debugging test failures by attaching to a running process, (7) debugging C/C++/Rust/Swift with LLDB, (8) any task where understanding runtime behavior requires a debugger. Triggers: "debug this", "set a breakpoint", "step through", "inspect variables", "why is this value wrong", "trace execution", "attach debugger", "runtime error", "segfault", "core dump".
Io.Github.DigitalDefiance/Ts Mcp Debugger
Enterprise debugging for Node.js/TypeScript with 25+ tools: breakpoints, profiling, hang detection
jdb-debugger
Debug Java applications in real time using JDB (Java Debugger CLI). Attach to running JVMs or launch new ones under JDB, set breakpoints, step through code, inspect variables, analyze threads, and diagnose exceptions. Use when debugging Java programs, investigating runtime behavior, or diagnosing production issues on JVMs with JDWP enabled.
