SFXMint MCP Server
Free CC0 sound effects for AI agents. Search 4,600+ sounds, get permanent hotlinkable MP3/WAV URLs, and generate new SFX from text — no API key, no signup.
- Endpoint (Streamable HTTP):
https://sfxmint.com/mcp - Docs: https://sfxmint.com/api/docs
- Registry: published as
com.sfxmint/soundson the official MCP Registry - License of all audio: CC0 1.0 — public domain, commercial use welcome, no attribution required
Every sound is AI-generated (Stable Audio) or procedurally synthesized, so the library is copyright-clean by construction. Audio URLs are permanent, immutable, CORS-enabled and free to hotlink — safe to embed directly in generated apps, games and videos.
Quick start
Claude Code:
claude mcp add --transport http sfxmint https://sfxmint.com/mcp
Cursor / generic mcpServers config:
{ "mcpServers": { "sfxmint": { "url": "https://sfxmint.com/mcp" } } }
Prefer a skill over a server? This repo also ships an Agent Skill that uses the plain HTTP API — no MCP server required:
npx skills add flreey/sfxmint-mcp -y
It teaches the agent to ask by purpose (role → set → search) instead of guessing keywords, and carries ready-to-paste React / Phaser / plain-HTML snippets. Source: skills/sfxmint/SKILL.md.
Tools
| Tool | What it does |
|---|---|
get_role_sound | Start here. Ask by event — button-click, purchase-success, error, coin, rain-loop. Returns one QA-checked default plus alternates; plain-English aliases work |
get_sound_set | A coherent kit for one product in one call (15 sets: ui-crisp, retro-game, checkout, platformer, ai-coding-tool, …) |
search_sounds | Free-text search over 4,600+ sounds; never returns empty (semantic fallback) |
get_sound | Full metadata for one sound (incl. generation prompt, measured acoustics, license) |
generate_sound | Text-to-SFX (output 1–12 s, takes 10–60 s to render); returns permanent URLs. Rate-limited 3/day per client |
get_job | Status of a generation job |
Example
"Find me a rain ambience loop" →
search_sounds(query: "rain ambience")→https://sfxmint.com/dl/ambience-rain-01.mp3(CC0, hotlink-safe, 11 s)
Rate limits & fair use
- Search/metadata: no auth, generous limits
- Generation: 3/day per IP on the MCP path (browser path: 5/day)
- Hotlinking is allowed and encouraged; files are served with long-lived immutable caching
