Visual setup and architecture guide for Rea

01 // How It Works & Runtime Architecture

By leveraging Python SDK / OpenAI API, the application isolates runtime dependencies while maintaining low-latency execution traces across multi-step LLM operations.

04 // Client Configuration (claude_desktop_config.json)

{
  "mcpServers": {
    "rea": {
      "command": "python",
      "args": [
        "-m",
        "rea"
      ]
    }
  }
}

Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).

05 // Step-by-Step Installation

Verified Process
  1. 1

    Clone morluto/rea from GitHub

  2. 2

    Install dependencies with pip install -r requirements.txt (or uv sync)

  3. 3

    Copy .env.example to .env and add your API keys

  4. 4

    Run the skill server and connect your AI client via stdio or HTTP

06 // Execution Boundaries & Security Safeguards

● Context Protection

Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.

● Directory Allowlisting

Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.

● Process Isolation

Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.

07 // Frequently Asked Questions

FAQ Schema Included

What is Rea and how does it empower AI agents?

Rea is an open-source document capability designed for AI clients and autonomous agents. Reverse engineer anything with agents, from app behavior down to native binaries.

How do I install and configure Rea?

Follow the step-by-step installation: 1) Verify your runtime (Python 3.10+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.

Which AI clients and developer harnesses support Rea?

Rea is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.

What security boundaries and sandboxing safeguards does Rea enforce?

Rea executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.

Is Rea free and open source?

Yes, Rea is published under the MIT open-source license. You can inspect the source code and contribute on GitHub at https://github.com/morluto/rea.
