Decepticon: REA reversing service and subagent tools

An optional reversing workload in BitterSecurity’s Decepticon wraps rea-agents and Ghidra inside a dedicated HTTP/MCP container and exposes three tools to its reverser subagent. It pins the inspected binary by SHA-256 and exports REA Evidence files to the shared workspace before returning results.

Requirements & limits

The optional Decepticon REA integration uses Node.js 22, OpenJDK 21, Python 3, Ghidra 12.1.4 and [email protected] in an HTTP/MCP container with a shared /workspace mount and port 8892.
Setting DECEPTICON_REA_URL loads rea_status, rea_find_tools and rea_call_tool for the reverser subagent. Without it, the subagent uses local Radare2 and triage tools.
rea_call_tool copies the target binary to a read-only file, verifies its SHA-256, and exports evidence-<sha256>.json and manifest.json. trace_native_values first runs analyze_function for source Evidence.
Unit tests mock HTTP responses, FastMCP sessions and tools to check filtering, arguments, Evidence wiring and fallback behavior.
