MCP.Pizza Chef: radareorg

Built on radare2, the long-running open-source toolkit that security researchers use to pick software apart, this gives an assistant the run of a program file: listing the functions and text inside, turning raw machine instructions back into readable code, and labelling what it finds so the next pass makes sense. Everything happens on your own computer, with no account and nothing to pay for, though you do have to install radare2 first. A read-only mode keeps the assistant from changing anything.

Installation

radare2-mcp FAQ

Is this still being maintained?
Yes. It is run by the radare2 project itself and had code changes as recently as August 2026, so it tracks current radare2 releases.
Do I need to pay for anything or sign up for an account?
No. Both radare2 and this add-on are free and open source, and analysis happens on your own machine. The only password involved is one you invent yourself, and only if you choose to run it over a network.
Which apps does it work with?
Claude Desktop, VS Code with Copilot Chat, Zed, Codex and other assistants that support MCP. Setup is a short block of settings text in each app.
Can I use this to work out whether a downloaded file is safe?
Yes, up to a point. Your assistant can open the file, read the text and web addresses buried in it, and describe what the code appears to do. It is a strong first look, not a verdict from an antivirus product.
Is it hard to set up?
It is the hardest tier. You install radare2, then either use its package command or build a container image, before pasting settings into your assistant. Comfortable with a terminal is the bar here.
Can it change files, or only look at them?
It can do both. Beyond reading, it renames functions, records notes, and while debugging it can write to a running program's memory. Starting it in read-only mode removes all of that.
