Bloom MCP Guide
Generate Ad Creative at Scale with AI
Create hundreds of on-brand ad images for Meta, Google, and TikTok — directly from Claude, Cursor, or any MCP client. No designer. No templates. No manual resizing.
You need 50 ad variations by Friday. Your designer is booked. AI image tools generate generic output that doesn't match your brand. So you're back in Canva, swapping colors and resizing manually. There's a better way.
How it works
Four steps from a website URL to production-ready ad creative.
Set up Bloom
Create an API key and connect Bloom to your MCP client. Works with Claude Code, Cursor, VS Code, and Windsurf. Follow the setup guide.
Onboard your brand
Paste your website URL. Bloom scrapes your site and extracts your full visual identity — logo, colors, fonts, design aesthetic, composition patterns. Takes about 30 seconds.
“Add this brand to Bloom: https://your-brand.com”
Generate ad creative
Describe what you need. Bloom generates on-brand images in any aspect ratio — 1:1 for feed, 4:5 for Meta, 9:16 for Stories. Generate one at a time or batch dozens from a single prompt.
“Generate a summer sale banner with a product hero shot, bold typography, and vibrant energy. Use a 4:5 aspect ratio for Meta.”
“Now make an Instagram Story version announcing free shipping weekend.”
Edit, resize, and iterate
Not quite right? Edit in natural language — “make the headline bigger” or “swap the background to outdoor.” Then resize your best performers across every placement in one call. AI recomposes the image for each aspect ratio.
“Make the headline text larger and more prominent.”
“Now resize that for Instagram Stories.”
What you get
On-brand every time
Every image matches your visual identity. Your colors, your aesthetic, your composition style — automatically.
Every placement covered
Feed, Stories, banners, display. Generate in 10 aspect ratios and resize between them with AI recomposition.
Generate, edit, resize in one flow
No switching tools. Generate an ad, refine it with natural language edits, resize for every placement — all from chat.
Reference images for precision
Upload a competitor's ad or a mood board image. Bloom uses it as style guidance while keeping the output on your brand.
Who this is for
Frequently asked questions
What ad platforms does Bloom support?
Bloom generates static image ads for any platform: Meta (Facebook and Instagram), Google Display, TikTok, LinkedIn, Pinterest, and more. Generate in any aspect ratio — 1:1 for feed, 4:5 for Meta, 9:16 for Stories, 16:9 for banners — and resize between them with AI-powered recomposition.
How does Bloom keep ads on-brand at scale?
When you onboard a brand, Bloom analyzes the entire visual identity from the website or Instagram: design aesthetic, composition style, color usage, and brand personality. Every image it generates carries that DNA. Whether you generate 5 or 500, they all look like your brand made them.
Can I use reference images for ad concepts?
Yes. Upload a competitor's ad, a mood board image, or a previous campaign asset as a reference. Bloom uses it for style and content guidance while keeping the output on your brand. Upload via the API, then pass the image ID when generating.
How is this different from AdCreative.ai or Canva?
AdCreative.ai uses templates and stock imagery to generate ad variations. Canva requires manual design. Bloom learns your brand's visual identity and generates original images that match your aesthetic automatically — no templates, no manual arrangement, no design skills required.
What does it cost to generate ads at scale?
Bloom starts at $20/month (Plus plan, 50 image credits) with a $5 trial for 3 days. Each 2K image costs 1 credit, 4K costs 2. Annual plans save 20%. See the full pricing breakdown on our pricing page. See pricing
