Is sfxmint live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is sfxmint free to use?

Yes — the hub reached it with no key and no payment.

What tools does sfxmint have?

4 tools: get_sound_set, search_sounds, get_role_sound, get_sound.

Is sfxmint safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• search_sounds reads open 11h ago

  Free-text search over the SFXMint library of free CC0 sound effects. Use it for sound descriptions, additional constraints or gaps left by another tool. Choose get_role_sound for a named event or get_sound_set for multiple events when that fits the task; these are task branches, not a fixed sequence. Hard constraints (duration, loop, format, excluded words) always apply. results hold sounds whose text has every word of the query. When there are none, closest lists the nearest sounds that meet every hard constraint, best first, each with missing_terms: judge them from title and description and let the user listen. library_fit says how well the library covers the request (full, close, weak, none). Returns direct, hotlinkable MP3 and WAV URLs and verified OGG (Vorbis) URLs where available, no attribution required, plus acoustics measured from the WAV (onset_ms, peak_ms, audible_ms, attack_ms, tail_ms, centroid_hz, peak_dbfs, rms_dbfs), character labels like 'bright · punchy · tight', loop/file-QC status, and score/match as ranking evidence only (role = known role default, exact = all words hit, partial = some words hit, semantic = nearest by meaning). Free use is MP3: downloading a WAV takes a download pack, and wav_url without one answers 402 wav_needs_pack with the mp3_url to use.

• get_role_sound reads open 15h ago

  Choose this when the task calls for a sound for a named event or interaction — a button click, purchase success, error beep, level-up, dialogue blip, notification. Pass the role as plain words: role ids (click, success, purchase-success, dialogue-blip, notification…) and common aliases (button click, ka-ching, jump scare, text blip…) are all accepted. Returns a qualified candidate for that role when one satisfies the requested constraints, with MP3 and WAV URLs, 2-3 alternates and the family page for browsing more. Free use is MP3: downloading a WAV takes a download pack, and wav_url without one answers 402 wav_needs_pack with the mp3_url to use. Download selected files locally and retain originals. Task-permitted processing requires a recipe, output SHA256, renewed file checks and a listening check. Other task-permitted sources or local synthesis may be mixed in. Optional style: crisp (short, bright, dry), soft (darker, gentler), spacious (reverb, longer tail), balanced (default: most typical). For multiple events consider get_sound_set; use search_sounds for a description or a gap. These are task branches, not a fixed sequence. Unknown roles return not_found with the full role list; GET https://sfxmint.com/api/v1/roles lists roles with aliases.

• get_sound reads open 15h ago

  Get full metadata for one sound by slug, including download URLs, description and acoustics measured from the WAV (silence before the sound, where it peaks, audible length, attack, tail, brightness, levels, character labels).

• get_sound_set reads unknown never probed

  Get a coherent set of sounds for an app or game in one call — one sound per role, with format metadata, hashes and stable download URLs. Use it when the task needs a whole kit; use get_role_sound for one event. Listen to the files in context. Sets include UI styles, game and app scenarios, acoustic-drum-kit, animal-calls (15 isolated calls), and dungeon-traps (6 isolated mechanisms).
