SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and validate a unique, robust byte signature for a function using IDA Pro MCP so it can be reliably located across binary updates.

Core Features & Use Cases

  • Automatically resolves to the true function start from a given address.
  • Performs instruction-boundary aware wildcarding to produce compact, portable signatures.
  • Uses pattern-matching and binary search to verify uniqueness against the binary image.
  • Use case: when updating binary tooling across game patches, you can regenerate a signature that still matches.

Quick Start

Provide the target function address and an active IDA Pro MCP connection, then run the script to generate and validate a unique function signature.

FAQPage Schema
How do I generate a stable function signature for binary analysis across updates?

To generate a stable function signature, you can use a pattern-based approach with IDA Pro MCP that resolves the true function start, applies instruction-boundary aware wildcarding, and verifies uniqueness against the binary image to ensure it survives updates.

Why does my pattern signature break after a binary update or game patch?

Pattern signatures often break after binary updates due to shifted offsets or changed compiler optimizations. Generating instruction-boundary aware wildcard signatures helps create portable patterns that survive these binary changes by ignoring volatile bytes.

How do I verify that a byte signature is unique within a binary image?

You can verify a byte signature is unique by using pattern-matching and binary search against the full binary image, ensuring the generated signature matches exactly one location and avoids collisions during reverse engineering.

Does IDA Pro MCP support automatic wildcarding for function signatures?

Yes, using IDA Pro MCP you can perform automatic wildcarding of bytes to produce compact, portable function signatures, which automatically resolves the true function start from a given address before generating the pattern.

What is the best way to locate a function across different binary versions?

The best way to locate a function across binary versions is by generating a unique, robust byte signature using pattern-based matching, which involves resolving the true function start and applying progressive verification against the binary image.

Do I need to manually resolve the function start address before generating a signature?

No, you do not need to manually resolve the function start address. The signature generation process automatically resolves to the true function start from a given address before applying wildcarding and pattern verification.
