Binary Ninja reverse engineering

Use Binary Ninja when the user explicitly selects it, when its ILs materially help data-flow analysis, or when IDA/Ghidra/radare2 results need an independent cross-check.

Start safely

1. Confirm the repository case scope is ready before acting on a target.
2. Check skills/tool-index.md for binaryninja; Binary Ninja is commercial software and must be installed manually with a valid Vector 35 license.
3. Work on a copy when applying patches or saving database changes.
4. Record imports/exports, entry points, architecture, and file hash before promoting findings.

Choose the integration

• GUI or Python API: preferred when Binary Ninja is already open or the user wants direct interactive analysis.
• Community MCP bridge: use only when explicitly requested and after reviewing the third-party plugin boundary. Keep the Binary Ninja HTTP listener on 127.0.0.1:9009; do not enable network exposure by default.
• Fallback: use ghidra-reverse, ida-reverse, or radare2 when Binary Ninja is unavailable or its license/API cannot open the target.

The reviewed community integration is fosdickio/binary_ninja_mcp, GPL-3.0, plugin metadata version 1.1.0, minimum Binary Ninja build 4000. The repository is not an official Vector 35 component. This skill was checked against commit 8c5134ee46e2bf44f9a4d846bd971c3e39b3e306 on 2026-09-03.
