Evolink Image — AI Image Generation & Editing

Generate and edit AI images with 19 models including GPT Image 1.5, GPT-4o Image, 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 — 19 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. 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.

External Endpoints

Service	URL
Generation API	`https://api.evolink.ai/v1/images/generations` (POST)
Task Status	`https://api.evolink.ai/v1/tasks/{task_id}` (GET)
File API	`https://files-api.evolink.ai/api/v1/files/*` (upload/list/delete)

Security & Privacy

EVOLINK_API_KEY authenticates all requests. Injected by OpenClaw automatically. Treat as confidential.
Prompts and images are sent to api.evolink.ai. Uploaded files expire in 72h, result URLs in 24h.

Setup

Get your API key at evolink.ai → Dashboard → API Keys.

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.

MCP Tools

Tool	When to use	Returns
`generate_image`	Create or edit an image	`task_id` (async)
`upload_file`	Upload local image for editing/reference	File URL (sync)
`delete_file`	Free file quota	Confirmation
`list_files`	Check uploaded files or quota	File list
`check_task`	Poll generation progress	Status + result URLs
`list_models`	Compare available models	Model list
`estimate_cost`	Check pricing	Model info

Important: generate_image returns a task_id. Always poll check_task until status is "completed" or "failed".

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_file with file_path, base64_data, or file_url → get file_url (sync)
Use file_url as image_urls or mask_url for generate_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_task every 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."

Error Handling

HTTP Errors

Without MCP Server

Use Evolink's file hosting API for image uploads (72h expiry). See references/file-api.md for curl commands.
