    How to connect

    How to connect sounds to Claude

    The server address to paste into Claude settings:

    https://sfxmint.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect sounds to ChatGPT

    The server address to paste into ChatGPT settings:

    https://sfxmint.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    search_soundsFree-text search over 4,600+ 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. Exact keyword matches come first, then semantic nearest neighbours; hard constraints are applied before the result limit and a request may validly return no qualified candidate with near-match diagnostics. Returns direct, hotlinkable MP3/WAV URLs and verified OGG (Vorbis) URLs where available — no API key, no attribution required — plus measured acoustics (attack_ms, tail_ms, centroid_hz), 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).
    get_role_soundChoose 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, rain loop. Pass the role as plain words: role ids (click, success, purchase-success, dialogue-blip, rain-loop…) 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/WAV URLs, 2-3 alternates and the family page for browsing more. Five core game roles include content_check (verified/unverified/rejected), scoped to scene, role, format and exact file SHA256; unverified previews are not certified suitable. Download selected files locally and retain originals. Task-permitted processing requires a recipe, output SHA256, renewed file checks and a listening check; changed bytes do not inherit content review. 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). Loop roles require prepared loop metadata; WAV seam evidence and MP3 padding are reported separately and may remain unknown. 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_soundGet full metadata for one sound by slug, including download URLs, generation prompt and measured acoustics (attack/tail/brightness + character labels).
    get_sound_setGet 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. Check content_check: verified/unverified/rejected is bound to the exact role, format and file SHA256; unverified files still require listening in context. Sets include UI styles, game and app scenarios, acoustic-drum-kit, animal-calls (15 isolated calls), and dungeon-traps (6 isolated mechanisms).
