Dali by Lulu — Claude Code MCP server: prompt scoring
Dali rates prompts and images before generation, then points to missing creative elements. It fits ad concepts that need a market-based check.
claude mcp add --transport http dali https://dali.getlulu.dev/mcpWhat Dali by Lulu does
Dali provides two core checks. score_prompt reviews a generation prompt before a model call, while score_creative compares an image with ad creatives that have stayed live in the market. enhance_prompt can produce a revision brief when the prompt needs more detail.
Its reference set comes from the public Meta Ad Library and is prepared in advance. The server looks for visually similar winning ads, then reports missing traits such as camera movement, lighting, scene physics, or a visible offer. It reads prepared stores instead of scraping and embedding during each request.
Here, “winning” means long-running, not measured conversion rate. A Dali score is therefore not a CVR forecast. You can use the hosted MCP over HTTP or run the local package with uvx dali-mcp.
What it helps with
- check a generation prompt before spending a credit
- spot missing features in an ad image
- compare a creative with long-running ads
- build a revision brief for a prompt
Example prompts for the agent
- Use Dali to score this Veo 3 prompt and tell me what to add before generating.
- Run Dali on
image_urlin thebeautycategory and identify the missing winning attributes. - Create a Dali enhancement brief for this advertising prompt.

Questions about Dali by Lulu
How do I install Dali by Lulu in Claude Code?
Add the hosted MCP with claude mcp add --transport http dali https://dali.getlulu.dev/mcp. Claude Code can then call the server.
What does Dali by Lulu do?
