A Model Context Protocol (MCP) server that helps any LLM (ChatGPT, Claude, etc.) instantly rewrite disappointing responses into one clean, high-quality prompt.
This MCP server analyzes the recent conversation, identifies what the user actually wanted, and generates a single, first-person improved prompt tailored to produce a better response from the assistant.
No noise.
No multiple choices.
Just one perfect next prompt — every time.
The server reads:
- The recent conversation window
- The last user message
- An optional user comment (why they disliked the answer)
And analyzes:
- What the user was trying to accomplish
- Why the assistant’s prior answer failed
- What information or structure was missing
The MCP server generates a single optimized prompt that:
- Is written fully in first person
- (“Explain to me…”, “Give me…”, “Help me…”)
- Is self-contained
- The prompt works even if the model never saw the past conversation
- Is clear and specific
- Avoids generic references like “the user” or “previous discussion”
- Adds helpful structure when needed (steps, examples, analogies, UX guidelines, etc.)
Optional: Up to 2 lightweight alternatives may be included.
No matter how the user triggers the tool —
“use the tool”, “suggest a better prompt”, “rewrite this”, etc. —
the server always returns one single best prompt, not multiple choices.
