Unofficial REA Guide: Use doctor to Tell MCP Registration From Provider Readiness
tian521057 · reddit · 2026-10-29
The author publishes an unofficial configuration guide for REA (rea-agents), covering how to wire it into Claude Code, Codex or Cursor via MCP.
The core issue is that a successful setup does not mean the MCP client actually sees the tools; the guide separates the layers:
- Review the setup plan before approving;
- Fully restart the client so MCP registration reloads;
- Use doctor to distinguish MCP registration from native provider readiness;
- Platform-specific limits, including Windows native provider boundaries;
- A real terminal transcript plus explicit capability limits.
The site is free, requires no signup and has no paywall, with links to the official GitHub and npm; the author asks for feedback on whether the troubleshooting logic is clear and which MCP client to cover next.
