# RTCF — Prompt Improver (Remote MCP Server)

Turn rough requests into sharp, structured prompts, right inside Claude, ChatGPT, or any MCP client.

RTCF rewrites a messy request into the four parts every strong prompt needs: **Role, Task, Context, Format**. Works in Thai and English. Free tier included (5 credits/day, no sign-up).
