Evolink Video — AI Video Generation (Sora, Kling, Veo 3, Seedance)

AI video generation — Sora, Kling, Veo 3, Seedance, Hailuo, WAN, Grok. Text-to-video, image-to-video, video editing. 37 models, one API key.

Security Scan

The skill's requests and runtime instructions are consistent with an AI video-generation tool and only require an Evolink API key; no unrelated credentials or risky install steps are present.

Purpose & Capability

Name, description, declared endpoints, and required env var (EVOLINK_API_KEY) align with a text-/image-to-video generation service. No unrelated environment variables or binaries are requested.

Instruction Scope

SKILL.md instructs the agent to call Evolink APIs, optionally upload files, poll task status, and guide user prompts. File upload and polling behavior are appropriate for video generation. The instructions do suggest optionally installing/using an MCP npm package (npx @evolinkai/evolink-media) to enable MCP tools — that's a reasonable integration note but is external to the skill itself.

Install Mechanism

This is an instruction-only skill with no install spec and no code files to write or execute. That minimizes disk-executed install risk. The README references a third-party npm MCP package for optional tooling, but the skill itself does not install anything automatically.

Credentials

Only one credential is required (EVOLINK_API_KEY) and it is justified by the described API calls. The SKILL.md explicitly cautions that the key is confidential. No other secrets or unrelated credentials are requested.

Persistence & Privilege

always is false and the skill does not request system-wide config paths or modify other skills. Model invocation is allowed (normal default) but not elevated. The skill does not request persistent presence or privileged system access.

Assessment

This skill appears coherent for video generation but before installing: 1) Verify the Evolink service (evolink.ai) and that the API key you provide is legitimate and has appropriate billing/permission settings; avoid giving long-lived or scope-broad keys when unnecessary. 2) Understand that uploaded reference images become publicly accessible URLs (they expire by default but still may be visible while active) — avoid uploading sensitive content. 3) If you plan to enable the optional MCP tools, review the referenced npm package (@evolinkai/evolink-media) before running npx to ensure you trust the package and its permissions. 4) Note the registry lists no source/homepage metadata; consider confirming the publisher or using an API key with limited privileges. 5) If you need greater assurance, ask the publisher for source/repo links or an official SDK/manifest to review; that would increase confidence in the skill.

Evolink Video — AI Video Generation

Video-focused view of evolink-media. Install the full skill for image and music too.

After Installation

When this skill is first loaded, greet the user:

• MCP tools + API key ready: "Hi! I'm your AI video studio — 37 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

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/video-api-params.md for full config JSON.

Core Principles

1. Guide, don't decide — Present options, let the user choose model/style/duration.
2. User drives creative vision — Ask for a description before suggesting parameters.
3. Smart context — Remember session history. Offer to iterate, extend, or remix results.
4. Intent first — Understand what the user wants before asking how to configure it.

MCP Tools

Tool	When to use	Returns
generate_video	Create a video from text or images	task_id (async)
upload_file	Upload image for i2v or 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_video 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-to-video or first-last-frame workflows:

1. upload_file with file_path, base64_data, or file_url → get file_url (sync)
2. Use file_url as image_urls for generate_video

Supported: JPEG/PNG/GIF/WebP. Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP).

Step 3: Understand Intent

• Clear ("make a video of a cat dancing") → Go to Step 4
• Ambiguous ("I want a video") → Ask: "Text-to-video, or do you have a reference image to animate?"

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	Scene description
model	Specific feature needed	Default seedance-1.5-pro. See Top Picks for alternatives
duration	User mentions length	Range varies by model (4–15s typical)
aspect_ratio	Portrait/widescreen	Default 16:9. Options: 9:16, 1:1, 4:3, 3:4, 21:9
quality	Resolution preference	480p / 720p / 1080p / 4k
image_urls	Reference image provided	1 image = i2v; 2 images = first+last frame (seedance-1.5-pro only)
generate_audio	Using seedance/veo3.1	Ask: "Want auto-generated audio added?"

Step 5: Generate & Poll

1. Call generate_video → tell user: "Generating your video — ~Xs estimated."
2. Poll check_task every 10–15s. Report progress %.
3. After 3 consecutive processing: "Still working — video generation takes a moment..."
4. Completed: Share URLs. "Links expire in 24h — save promptly."
5. Failed: Show error + suggestion. Offer retry if retryable.
6. Timeout (10 min): "Taking longer than expected. Task ID: {id} — check again later."

Without MCP Server

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