modbender 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.

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.

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_filewithfile_path,base64_data, orfile_url→ getfile_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
- Simple (
- 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:morf— optional
- Optional for both modes:
duration: target length 30–240s (omit to let model decide)negative_tags: styles to excludemodel: defaultsuno-v4. Suggestsuno-v5for 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_taskevery 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."
