binary-patch-mcp

name	binary-patch-mcp
description	Use when the task requires emitting a patched binary copy through the local MCP tool lane, especially for short instruction patches or explicit byte replacements.

Binary Patch MCP

Use this skill when the user explicitly wants a patched output binary on disk.

Tool Surface

• binaryPatchHelp()
• binaryPatchInspect(...)
• binaryPatchBytes(...)
• binaryPatchAssemble(...)

Best-Fit Tasks

• Patch a copied binary at a known file offset, RVA, or VA
• Replace a short instruction sequence with assembled bytes
• Validate expected original bytes before applying a patch
• Keep reverse engineering and emitted patching as separate steps

Guidance

• Prefer Ghidra for understanding the binary and deciding what to patch.
• Prefer binaryPatchInspect(...) before patching when the target addressing needs confirmation.
• Prefer writing to a new output_path, not overwriting the original sample.
• Use expected_original_hex when you know the original bytes and want a guardrail.
• Treat this as an output-emission tool, not an analysis tool.
