# Hydra Engine

> One headless Ghidra that every AI agent shares: a long-lived daemon that holds projects, analysed programs and warm decompilers, used by many clients at once (Claude Code, Codex, OpenCode, QoderCLI, MCP servers, scripts). Warm decompiles take about 7 ms. Apache-2.0, derived from NSA's Ghidra (12.3 DEV). It works best with Hydralysis (https://github.com/RusticStack/Hydralysis), the MCP server and CLI with twenty reverse-engineering tools that runs on it.

Set up both by asking an AI harness: "Set up Hydralysis and Hydra Engine from github.com/RusticStack/Hydralysis."
