Clarifyprompt tools (7, 2 write)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
list_categoriesList all available prompt optimization categories with platform counts including custom platforms
list_modesList available output modes for prompt optimization (concise, detailed, structured, step-by-step, bullet-points, technical, simple)
list_platformsList available platforms for a category, including custom registered platforms.
optimize_promptOptimize a prompt for a specific AI platform. Supports 7 categories and 58+ platforms including Midjourney, DALL-E, Stable Diffusion, Sora, Runway, HeyGen, ElevenLabs, Suno, Claude, ChatGPT, DeepSeek, Cursor, Jasper, and more. Also supports custom registered platforms. Category and platform are auto-detected when omitted.
register_platformRegister a new custom AI platform for prompt optimization. The platform must belong to an existing category. Use instructions or instructions_file to provide detailed guidance on how prompts should be optimized for this platform.
unregister_platformwrite actionRemove a custom platform registration. Cannot remove built-in platforms, but can remove instruction overrides from them.
update_platformwrite actionUpdate a custom platform or add/override instructions on a built-in platform. For built-in platforms, only instructions, instructions_file, and syntax_hints_append are supported.

ClarifyPrompt MCP
A context-aware MCP prompt compiler that transforms vague prompts into platform-optimized prompts for 60+ AI platforms across 7 categories — grounded in your workspace signals (CLAUDE.md, AGENTS.md, .cursorrules, package.json), resolved intent, and the capabilities of the target model.
Send a raw prompt. ClarifyPrompt gathers the right context, resolves what you're actually trying to do, and returns a version specifically optimized for Midjourney, DALL-E, Sora, Runway, Higgsfield, ElevenLabs, Claude, ChatGPT, Cursor, or any of the 60+ supported platforms — with the right syntax, parameters, structure, and grounding.
New in 1.15.0: Nano Banana (Google Gemini 2.5 Flash Image) is now a built-in image platform — optimizeprompt(platform: "nano-banana") compiles image prompts in its native style (natural-language scene direction, photographic terms, edit-preserving-identity phrasing, in-image text). Plus latest-model compatibility across every provider: claude-sonnet-5, gpt-5/o-series, and Gemini reject temperature and/or maxtokens; the client now sends the right parameters (proactively for known reasoning ids, and learns the rest from a 400). Verified live against Anthropic, OpenAI, Gemini, and Ollama Cloud. See CHANGELOG.md.
New in 1.14.1: Portable-by-default text output — a chat/document/code prompt with no explicit platform now stays platform-neutral instead of quietly defaulting to Claude's idioms (XML tags); name a platform to opt into vendor-specific tuning. Plus the MCP Apps compose panel now shows a for badge and a clean Your prompt → Optimized before/after (with a show changes toggle) instead of an always-on diff. See CHANGELOG.md.
New in 1.14.0: An interactive compose panel via MCP Apps. In hosts that speak the io.modelcontextprotocol/ui extension (Claude Desktop, ChatGPT, Cursor, VS Code, …), composeprompt renders a live panel: original-vs-optimized view, all six critique scores, the pipeline stages, and Accept / Revise** actions — Accept records the outcome into ClarifyPrompt's memory loop, Revise sends your feedback back into the chat. One self-contained ui:// resource; hosts without the extension see zero change. See CHANGELOG.md.
New in 1.13.0: Plain-language rewrites. Optimized prompts now stick to common, everyday words instead of drifting into formal vocabulary ("use", never "utilize") — specificity comes from concrete details, not fancier synonyms. critiqueprompt gained a 6th default dimension, plainlanguage, so auto_revise loops correct register drift automatically. Also fixed: an explicit mode (e.g. simple) is no longer silently dropped for small local models under compact system-prompt shaping. See CHANGELOG.md.
How It Works
ClarifyPrompt does two things a plain prompt template can't. Every output below is a real, unedited capture from optimize_prompt run against this repo (see Provenance at the end of this section).

Clarifyprompt: common questions
- Is Clarifyprompt MCP server safe?
- Mostly: it is graded B (77/100). Read the Clarifyprompt safety report
- How do I install Clarifyprompt?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does Clarifyprompt need an API key?
- Yes. The registry entry asks for
LLM_API_KEY. - Is Clarifyprompt maintained?
- The last commit was 113 days ago (2026-07-14). The latest release is v1.1.3.
- What can I use instead of Clarifyprompt?
- Servers from other publishers that do the same job: Image MCP server, LLM Sandbox MCP server and Agent-Native Analytics MCP server.
- How does Clarifyprompt compare with other AI and agents MCP servers?
- safety score 77/100 (higher than 50% of 4,460 AI and agents servers); tools 7 (the typical AI and agents server has 6); tools that change things 29% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
