Category: Cybersecurity

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "corvus": {
      "command": "dnx",
      "args": [
        "CorvusRE",
        "--yes"
      ]
    }
  }
}

Run this in your terminal

claude mcp add corvus -- dnx CorvusRE --yes

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "corvus": {
      "command": "dnx",
      "args": [
        "CorvusRE",
        "--yes"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "corvus": {
      "type": "stdio",
      "command": "dnx",
      "args": [
        "CorvusRE",
        "--yes"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Corvus safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.12.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need .NET on your computer.

Corvus

English · 简体中文 · 日本語

MCP server for reverse engineering and security analysis of compiled programs: .NET assemblies and native PE, ELF and Mach-O binaries.

One self-contained binary. Nothing is uploaded; nothing it reads is executed by default.
Tools and output can change between releases; see the release notes.

Quick start

Windows (PowerShell):

irm https://github.com/Albasha0x0/Corvus/releases/latest/download/install.ps1 | iex

Linux and macOS:

curl -fsSL https://github.com/Albasha0x0/Corvus/releases/latest/download/install.sh | sh

The installer verifies the download and registers Corvus with the MCP clients it finds. Restart the client and ask:

Load app.dll with Corvus and explain how it builds its export file. Cite the methods you read.

Plugin, container image and other clients: installation.
From a terminal: corvus decompile_member --load app.dll member=Ns.Type::Method (command line).
Builds: win-x64, win-arm64, linux-x64, linux-arm64, linux-musl-x64, linux-musl-arm64, osx-x64, osx-arm64.

How it works

The agent calls Corvus over MCP; every result is bounded, every list pages, every error names the next step.
Corvus's own engine reads native code (x86, x64, ARM32, ARM64); IDA or Ghidra, when installed, add pseudocode.
Edits happen in memory; the agent reviews the diff and saves a patched copy.

What it reads
