rea-rs — Native Rust Binary Triage, Disassembly & Reverse Engineering for AI Agents
rea-rs is a fast, memory-safe Rust binary analysis toolkit and MCP server that equips AI coding assistants to inspect ELF, PE, and Mach-O executables. It performs control-flow graph recovery, string and symbol extraction, entropy packing detection, and multi-architecture disassembly in milliseconds.
$ cargo install rea-rs
Architected for Speed & Reliability
Engineered from the ground up in memory-safe Rust with zero unnecessary dependencies.
Sub-5ms Execution Startup
Replaces Node.js with native machine code. Immediate startup and triage for command-line workflows and agent loops without V8 compilation lag.
Tri-Format Binary Parser
Built-in parsing for Mach-O (Apple Silicon / Intel), ELF (Linux / Android), and PE (Windows) headers, sections, segment maps, imports, and exports.
Control Flow Graph (CFG)
Extracts basic blocks, function boundaries, jump tables, and call graph hierarchies into structured JSON or visual ASCII graphs for quick analysis.
Native MCP Server for Agents
Direct Model Context Protocol integration allows Claude Code, Cursor, Codex, and Windsurf to inspect disassembly and binary structures on the fly.
Entropy & Security Auditing
Computes Shannon entropy across binary sections to spot packed payloads, encryption blocks, missing stack canaries, and DEP/ASLR vulnerabilities.
Zero External Dependencies
Self-contained static executable with zero required system shared libraries or dynamic interpreter dependencies.
Get Started in Seconds
Install via Cargo and run immediately on macOS, Linux, or Windows.
# Install from source
cargo install --git https://github.com/bhubbard/rea-rs
# Analyze binary metadata, headers, and security mitigations
rea analyze ./my_target_binary
# Extract Control Flow Graph for a specific symbol
rea cfg --func main ./my_target_binary
# Run native MCP server for AI pair programmers
rea mcpEngine Architecture
Streamlined execution pipeline with deterministic memory isolation and zero runtime overhead.
