CorvusBLOCK
Reverse-engineering MCP server for AI agents: .NET and native PE/ELF/Mach-O analysis, decompilation, cross-references and patching. IDA and Ghidra optional.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
Reverse engineering for AI agents. Corvus is an MCP server that lets your agent read, trace, compare and patch compiled programs: .NET assemblies and native PE, ELF and Mach-O binaries. One self-contained binary, no runtime to install, nothing executed, nothing uploaded.

Quick start
Windows (PowerShell):
irm https://raw.githubusercontent.com/Albasha0x0/Corvus/main/install.ps1 | iex
Linux / macOS:
curl -fsSL https://raw.githubusercontent.com/Albasha0x0/Corvus/main/install.sh | sh
The installer verifies the download against the release's SHA256SUMS and registers Corvus with the MCP clients it finds. Restart your client and ask:
Load app.dll with Corvus and explain how it validates a license key. Cite the methods you read.
From a terminal: corvus decompile_member --load app.dll member=Ns.Type::Method (command line).
How it works
Your agent calls Corvus over MCP. Corvus answers with bounded, structured results: every list pages, every error names the next step, and long results are kept for read_result

Questions
What is the Corvus MCP server?
Reverse-engineering MCP server for AI agents: .NET and native PE/ELF/Mach-O analysis, decompilation, cross-references and patching. IDA and Ghidra optional.
Is Corvus safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (57/100) and found 2 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does Corvus need?
No credential environment variables were found in its source, so it appears to need none.
How does Corvus run?
It speaks stdio, so it runs as a local process your client starts.
How current is this page?
The grade is for one exact copy of the source (f8599218a09d), read on 2026-10-14. The repository is watched and re-audited when it changes.
