REA = Reverse Engineer Anything: an open source MCP server that lets Claude Code, Cursor or Codex drive Ghidra and IDA to map how compiled software really works. Point it at the Access database, VB6 tool or InfoPath form your client can't explain, and you get a feature map with evidence. Then agents rebuild it on Power Platform.
📘 The legacy to Power Platform playbook:
1. Get the rights first: only analyze software you own or are authorized to examine.
2. Connect REA to Claude Code, Codex or Cursor: npx rea-agents setup
3. Point it at the app, one feature at a time: "Explain how assignment works. Show the evidence."
4. Triage: Seen = spec, Inferred = confirm, Unknown = workshop.
5. Model the data in Dataverse.
6. Rebuild screens and logic: model-driven app or Power Pages, plus flows.
7. Prove parity: every Seen finding becomes a test.
8. Lock it down: rules on the server.
