Yes, you run Claude Code or Cursor on your own machine, and REA runs there too. REA is an MCP server: the agent is the thing you talk to, and it calls REA's tools when you ask it to look at an app. Pick one agent, you do not need both.

Setup:

1. Install Node.js (22.23.4+, 24.22.1+ or 26.12.1+). npm comes with it.

2. In a terminal, run:

   npx rea-agents setup

   It asks which agents to configure (Claude Code, Cursor, Codex and others), shows the changes it wants to make, and applies them after you approve. That registers REA's MCP server with the agent and installs REA's workflow instructions.

3. Restart the agent it names at the end.

4. Open Claude Code or Cursor and ask in plain words, for example: "Understand how search works in the Notes app, show me the evidence, and build a similar feature for my project." The agent calls REA itself.

What needs extra software: JavaScript, Electron and website analysis works out of the box. Native binaries need a decompiler (Hopper, Ghidra, IDA or Kuna); setup offers to install Hopper for you.

To confirm it is wired up, run npx rea-agents doctor --client claude_code (or --client cursor). In Claude Code, claude mcp list should show rea.

Claude Code also has a plugin route (/plugin marketplace add morluto/rea, then /plugin install rea@rea). Use either setup or the plugin, not both, or you end up with two REA servers.

Full guide: docs/installation.md and rea.tools/guides.
