Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 195 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name sfxmint.

  • Pass
    Lists tools

    tools/list returned 4 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 195 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 195 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    14 of 14 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-31T11:00:41.688196Z, within 180 days.

Capabilities

Tools 4

get_role_sound

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.

Discovered
get_sound

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).

Discovered
get_sound_set

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).

Discovered
search_sounds

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.
