PromptRefiner
Wire your coding agent to turn rough creative briefs into polished prompts for Midjourney, Sora, and DALL-E without leaving the IDE.
Overview
PromptRefiner is a MCP server for the Build phase that optimizes generative prompts for Midjourney, Sora, and DALL-E through a remote SSE endpoint.
What is this MCP server?
- Remote MCP over SSE at prompt-refiner-mcp.vercel.app/api/mcp
- Targets Midjourney, Sora, and DALL-E prompt styles in one optimizer flow
- Optional premium path via payment-signature header (EIP-3009 TransferWithAuthorization)
- Fits agent-driven creative iteration without switching to a separate prompt lab
- Version 1.0.0 per published server schema
- Server version 1.0.0 in published MCP schema
- Single remote SSE endpoint: prompt-refiner-mcp.vercel.app/api/mcp
- Supports three named generative targets: Midjourney, Sora, DALL-E
What problem does it solve?
Solo builders waste cycles rewriting image and video prompts by hand while their agent already has context about the product and audience.
Who is it for?
Indie founders and marketers who already use MCP in Claude Code or Cursor and need consistent prompt quality across three major generative platforms.
Skip if: Teams that only need static copy SEO, local offline tooling with no remote dependency, or workflows that do not use Midjourney, Sora, or DALL-E.
What do I get? / Deliverables
After you add the remote MCP server, your agent can propose tighter, model-aware prompts you paste or pipe into your generative tools.
- Model-tuned prompt variants for Midjourney, Sora, or DALL-E
- Agent-callable optimization without a separate prompt notebook
- Documented remote endpoint ready for team MCP configs
Recommended MCP Servers
Journey fit
Prompt refinement for generative media sits in Build because solo builders invoke it while assembling marketing assets, prototypes, and agent workflows—not during early idea research. Agent-tooling is the canonical shelf for MCP servers that extend what Claude Code or Cursor can do mid-session, including remote SSE tools with optional paid settlement.
How it compares
Remote MCP prompt optimizer, not a bundled image-generation API or a local SKILL.md ritual.
Common Questions / FAQ
Who is PromptRefiner for?
It is for solo builders and creators who run Claude Code, Cursor, or similar agents and want Midjourney-, Sora-, and DALL-E-ready prompts without leaving the dev environment.
When should I use PromptRefiner?
Use it during Build when you are producing visuals or video concepts and need the agent to refine prompts before you render or iterate in external generative apps.
How do I add PromptRefiner to my agent?
Register the remote MCP server URL https://prompt-refiner-mcp.vercel.app/api/mcp as type sse in your client config; supply the payment-signature header only if your plan requires EIP-3009 premium settlement.
