REA MCP Setup

Build versioned REA installation commands and JSON/TOML client config. Choose your OS, native or JavaScript target and analyzer path; copy or download locally.

Client, system and analysis target

Choose Claude Code, Codex or Cursor, then Linux, macOS or Windows and Bash/zsh or PowerShell. Enter your installed Node version: REA 6.5.0 supports stable Node 22.19+, 24.11+ or 26+. Static JavaScript/Electron and .NET inspection need no native analyzer. Native analysis uses an existing supported analyzer; Ghidra and Hopper path overrides are optional.

Example: Codex, Linux, static JavaScript, Node 26.0.0. Merge the generated entry into ~/.codex/config.toml:

[mcp_servers.rea]
command = "npx"
args = [ "-y", "[email protected]", "mcp" ]
startup_timeout_sec = 30

Inspect setup before applying it

'npx' '-y' '[email protected]' 'setup' '--client' 'codex' '--dry-run'
'npx' '-y' '[email protected]' 'setup' '--client' 'codex'
'npx' '-y' '[email protected]' 'doctor' '--client' 'codex' '--json'

The page generates commands but never executes them. Official setup registers your selected client and installs matching investigation instructions. Manual JSON/TOML snippets only register MCP; preserve existing settings and other servers. Restart the agent after setup. Paths containing spaces are preserved as JSON/TOML strings.

Version and limits
