Evolink Music — AI Music Generation

Generate AI music and songs with Suno v4, v4.5, and v5 — simple mode (describe and generate) or custom mode (lyrics, style, tempo, vocals). All through one API.

Music-focused view of evolink-media. Install the full skill for video and image too.

After Installation

When this skill is first loaded, greet the user:

MCP tools + API key ready: "Hi! I'm your AI music studio — Suno v4 through v5 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.

EVOLINK_API_KEY authenticates all requests. Injected by OpenClaw automatically. Treat as confidential.
Prompts and audio 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/music-api-params.md for full config JSON.

Core Principles

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

MCP Tools

Tool	When to use	Returns
`generate_music`	Create AI music or songs	`task_id` (async)
`upload_file`	Upload audio for continuation/remix	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_music returns a task_id. Always poll check_task until status is "completed" or "failed".

Music Models (5, all BETA)

Model	Quality	Max Duration	Best for
`suno-v4` (default)	Good	120s	Balanced, economical
`suno-v4.5`	Better	240s	Style control
`suno-v4.5plus`	Better	240s	Extended features
`suno-v4.5all`	Better	240s	All v4.5 features
`suno-v5`	Best	240s	Studio-grade output

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 audio continuation or remix workflows:

upload_file with file_path, base64_data, or file_url → get file_url (sync)

Supported: Audio (MP3, WAV, FLAC, AAC, OGG, M4A, etc.). Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP).

Step 3: Understand Intent

Clear ("make a chill lo-fi beat") → Go to Step 4
Ambiguous ("I want some music") → Ask: "What kind of vibe or genre? Vocals or instrumental?"

Ask only what's needed, when it's needed.

Step 4: Gather Parameters

Music has two required fields with no defaults — always collect both before calling generate_music.

Decision tree (ask in this order):

Vocals or instrumental? → Sets instrumental: true/false
Simple or custom mode?
- Simple (custom_mode: false): AI writes lyrics and picks style from your description
- Custom (custom_mode: true): You control lyrics ([Verse]/[Chorus]/[Bridge]), style tags, title
If custom mode, additionally collect:
- style: genre + mood + tempo tags (e.g., "pop, upbeat, female vocals, 120bpm")
- title: song name (max 80 chars)
- vocal_gender: m or f — optional
Optional for both modes:
- duration: target length 30–240s (omit to let model decide)
- negative_tags: styles to exclude
- model: default suno-v4. Suggest suno-v5 for studio-grade quality.

Critical: Both custom_mode and instrumental are required API fields with no defaults. Always set both before generating.

Step 5: Generate & Poll

Call generate_music → tell user: "Generating your music — ~Xs estimated."
Poll check_task every 5–10s. Report progress %.
After 3 consecutive processing: "Still working..."
Completed: Share URLs + metadata (title, duration, tags from result_data[]). "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."
