mcp2agy-reverse

A command for reverse engineering compiled software, firmware, and network protocols. Reverse engineering means studying finished software to understand how it works when its source code is unavailable.

In plain words
What is it for?
Decompiling programs, tracing their behavior, unpacking firmware, examining encryption or hidden entry points, and reconstructing proprietary protocols.
Why use it?
It organizes static code analysis, runtime tracing, firmware unpacking, and protocol investigation in one workflow.

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

mcp2agy-reverse 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 yesterday.

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.

/reverse — Reverse Engineering & Binary Analysis Engine (v3.0.0)

0. Prime Directive & Operating Model

The Reverse Engineering engine reconstructs binary logic, algorithms, encryption schemes, and hidden entry points from compiled targets:

1. Capabilities & Workflow

1.1 Static Analysis & Decompilation

  • Disassembly (x86_64, ARM64, MIPS, RISC-V) via capstone and radare2.
  • Decompilation & CFG recovery via Ghidra headless scripts.
  • String extraction, XOR deobfuscation, crypto constant identification.

1.2 Dynamic Instrumentation & API Hooking

  • Runtime hooking of functions, parameters, and return values using frida.
  • Breakpoint tracing and memory inspection in GDB (pwndbg / gef).

1.3 Protocol & Firmware Reverse Engineering

  • Automated firmware extraction via binwalk / sasquatch.
  • Reverse engineering state machines and packet structures for proprietary TCP/UDP/WebSocket streams.

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.

mcp2agy-reverse is a skill published in the GitHub repository uziii2208/mcp2agy (1 stars, last pushed 2d ago), licensed MIT. It adds 75 tokens to every session and 845 once invoked, about $0.0004 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 2026-08-31.
