Promptheus

Overview

Promptheus is a Model Context Protocol server that refines prompts through AI-powered techniques. It uses adaptive questioning and supports over six LLM backends including OpenAI, Claude, Gemini, Groq, and others, helping you craft better prompts across multiple providers.

The server runs locally on your machine via the uvx promptheus command, which installs the Python package and connects over MCP stdio. It requires an API key for your chosen LLM provider. Promptheus is published under the MIT license at version v0.3.1, with source code available at abhichandra21/Promptheus on GitHub, where it has 17 stars.

Promptheus is listed in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this project, you can claim this listing to verify ownership and keep information up to date.
