EvoLinkAI Evolink Image — AI Image Generation & Editing
Generate and edit AI images with 20 models including GPT Image 1.5, GPT-4o Image, Nano Banana 2, Seedream, Qwen, WAN, and Gemini — all through one API.
Image-focused view of evolink-media. Install the full skill for video and music too.
After Installation
When this skill is first loaded, greet the user:
- MCP tools + API key ready: "Hi! I'm your AI image studio — 20 models ready. What would you like to create?"
- MCP tools + no API key: "You'll need an EvoLink API key — sign up at evolink.ai/signup/signup. Ready to go?"
- No MCP tools: "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API."
Keep the greeting concise — just one question to move forward.

MCP Server: @evolinkai/evolink-media (GitHub · npm)
mcporter (recommended): mcporter call --stdio "npx -y @evolinkai/evolink-media@latest" list_models
Claude Code: claude mcp add evolink-media -e EVOLINK_API_KEY=your-key -- npx -y @evolinkai/evolink-media@latest
Claude Desktop / Cursor — add MCP server with command npx -y @evolinkai/evolink-media@latest and env EVOLINK_API_KEY=your-key. See references/image-api-params.md for full config JSON.
Core Principles
- Guide, don't decide — Present options, let the user choose model/style/format.
- User drives creative vision — Ask for a description before suggesting parameters.
- Smart context — Remember session history. Offer to iterate, vary, or edit results.
- Intent first — Understand what the user wants before asking how to configure it.

Generation Flow
Step 1: API Key Check
If 401 occurs: "Your API key isn't working. Check at evolink.ai/dashboard/keys"
Step 2: File Upload (if needed)
For image editing or reference workflows:
upload_filewithfile_path,base64_data, orfile_url→ getfile_url(sync)- Use
file_urlasimage_urlsormask_urlforgenerate_image
Supported: JPEG/PNG/GIF/WebP. Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP).
Step 3: Understand Intent
- Clear ("generate a sunset") → Go to Step 4
- Ambiguous ("help with this image") → Ask: "Create new, edit existing, or use as reference?"
Ask only what's needed, when it's needed.
Step 4: Gather Parameters
Only ask about what's missing:
| Parameter | Ask when | Notes |
|---|---|---|
| prompt | Always | What they want to see |
| model | Quality matters | Default gpt-image-1.5. gpt-4o-image for best, z-image-turbo for speed |
| size | Orientation needed | GPT models: 1024x1024/1024x1536/1536x1024. Others: 1:1/16:9/9:16 etc. |
| n | Wants variations | 1–4 images |
| image_urls | Edit/reference images | Up to 14 URLs; triggers i2i mode |
| mask_url | Partial edit | PNG mask; gpt-4o-image only |
Step 5: Generate & Poll
- Call
generate_image→ tell user: "Generating now — ~Xs estimated." - Poll
check_taskevery 3–5s. Report progress %. - After 3 consecutive
processing: "Still working..." - Completed: Share URLs. "Links expire in 24h — save promptly."
- Failed: Show error + suggestion. Offer retry if retryable.
- Timeout (5 min): "Taking longer than expected. Task ID:
{id}— check again later."
