debug-session

debug-session is a command for Claude Code from SetsunaYukiOvO/x64dbg-mcp. It costs 8 tokens per session (457 once invoked), scanned A, original, MIT.

A command that starts a structured debugging-session assessment for a Windows program in x64dbg or x32dbg.

In plain words
What is it for?
Use it at the beginning of reverse-engineering or debugging work to understand the program's current state and environment.
Why use it?
It collects the target, loaded modules, threads, registers, current instructions, call stack, breakpoints, imports, and recognized functions in one report.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

debug-session scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a reverse engineering assistant connected to x64dbg/x32dbg via MCP. The user is starting a new debugging session.

Phase 1: Environment Check

  1. Call debug_get_state to determine the debugger state (running, paused, stopped).
  2. Call module_get_main to identify the target binary.
  3. Call module_list to enumerate all loaded modules.
  4. Call thread_list to see all threads and their status.
  5. Call register_list to capture the current register state.

Phase 2: Initial Analysis

  1. If paused at a valid address, call disassembly_at with the current instruction pointer (cip) and count: 20.
  2. Call stack_get_trace to get the call stack.
  3. Call breakpoint_list to check for existing breakpoints.
  4. Call module_get_imports on the main module to see what APIs it uses.
  5. Call function_list filtered to the main module to see recognized functions (may need script_execute with cfanal first).

Phase 3: Report

Present a structured summary:

=== Debug Session Overview ===
Target: [binary name and path]
State:  [paused/running/stopped]
Architecture: [x86/x64]

Modules: [count] loaded
  - [main module] (base: 0x...)
  - [key system DLLs]

Threads: [count] active
  - Thread [id] (current) at [address] [symbol if available]

Current Location:
  [disassembly of current position, 5-10 instructions]

Call Stack:
  [top 5 frames with symbols]

Existing Breakpoints: [count]
  [list if any]

Phase 4: Recommendations

Based on the issue description "$1", suggest:

  • Where to set breakpoints for investigation
  • Which modules/functions to examine
  • Relevant API functions to monitor
  • A step-by-step debugging strategy

If no issue is described, provide general recommendations based on the binary type and loaded modules.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

debug-session is a command published in the GitHub repository SetsunaYukiOvO/x64dbg-mcp (455 stars, last pushed 18d ago), licensed MIT. It adds 8 tokens to every session and 457 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
