MeiGen AI Design MCP is an MCP server that lets AI coding tools generate images and videos through cloud models, OpenAI-compatible APIs, or local ComfyUI, an interface for running image-generation workflows. It is for creating designs such as logos, product images, animations, and batches of visual variations from coding-agent environments. Its catalogue entries provide skills, commands, agents, a plugin, and a hook for using the server's design workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00123 | $0.01063 |
| Opus 5 | $0.00062 | $0.00531 |
| Sonnet 5 | $0.00025 | $0.00213 |
| Haiku 4.5 | $0.00012 | $0.00106 |
Grade A, and why
Social Thumbnail Workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Social Thumbnail Workflow
Generate cover art for short-video platforms (TikTok / Reels / Shorts) or vertical social feeds. Optimized for 9:16, high contrast, big-headline space, and 1-second feed legibility.
When to trigger
- User says "video thumbnail", "封面", "短视频封面", "Reels cover", "TikTok cover"
- User mentions "9:16" or "vertical poster" or "竖版海报"
- User describes content meant for mobile feeds and asks for visual
Design constraints (apply to every prompt)
- 9:16 aspect ratio — pass
aspectRatio: "9:16"explicitly to everygenerate_imagecall. Do NOT write--ar 9:16in the prompt. - High contrast — bold foreground subject against a strong color-block or gradient background. Tiny details get lost when scaled to a phone-feed thumbnail.
- Headline-friendly composition — leave a clear zone (top third or bottom third) for the user's title text. Mention this explicitly in the prompt: "leave top third clear for headline overlay".
- One focal point — feed thumbnails work when the eye lands in <1 second. Don't pack multiple subjects.
- Brand-safe color — when the user gives a brand color, pin it; otherwise default to high-saturation primary palettes (red / cobalt / orange / electric green) over muted tones.
Workflow
1. Clarify intent
Ask ONE question (per UX Rule 4 — don't batch-ask):
- "What's the headline text the cover needs to support?" (lets you reserve the right zone)
- OR if user already gave a clear theme: skip ask, plan directly.
2. Reference (optional but recommended)
Call search_gallery(category="Poster Design") for style reference; 146 curated entries are available. Show 3-5 thumbnails to the user if they want to pick a direction.
3. Plan 2-3 variants (default 3)
Distinct directions, not minor tweaks. For each, write a prompt that:
- Names the focal subject (1 person / 1 object / 1 typographic motif)
- Specifies background (color block / gradient / minimal scene)
- Specifies lighting / mood
- Calls out the headline-safe zone explicitly
- Includes contrast keyword ("high contrast", "bold colors")
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Social Thumbnail Workflow is a skill published in the GitHub repository jau123/MeiGen-AI-Design-MCP (1,749 stars, last pushed 1mo ago), licensed MIT. It adds 123 tokens to every session and 1,063 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
