Tài liệu
SFXMint MCP Server
Free CC0 sound effects for AI agents. Search 4,000+ 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.

claude mcp add --transport http sfxmint https://sfxmint.com/mcp

- 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
