Clarifyprompt

lumabyteco/clarifyprompt-mcp

Turns vague prompts into platform-specific syntax for 60+ AI tools across image generation (Midjourney, DALL-E, Stable Diffusion), video (Sora, Runway), audio (ElevenLabs), and coding assistants (Claude, Cursor). Exposes MCP tools that read workspace context files (CLAUDE.md, .cursorrules, package.json), resolve user intent, then rewrite your input with the right parameters, aspect ratios, quality flags, and structure for whichever platform you're targeting. Ships with an eval harness and runs over stdio. Reach for this when you're switching between creative AI tools and don't want to memorize each platform's prompt syntax or manually append --ar 16:9 --style raw every time you generate an image.

ground_promptStrict, retrieval-augmented variant of optimize_prompt; caller-provided sources are pinned at the highest priority so the rewrite is grounded in the material provided.
