Lots of Sounds combines a CC0 sound-effects library with browser audio tools, an online soundboard, a REST API, and a hosted MCP server. The maker says sounds can be used commercially without attribution, including in videos, games, apps, and streams. Its API searches by keyword, filters by tags, category, and duration, and provides signed URLs for streaming or downloading MP3 files. It uses standard HTTP requests with an x-api-key header and does not require an SDK. Free browser tools convert and trim audio and generate waveform images; the maker says processing takes place on the user's device. The hosted MCP server connects to Claude, Cursor, ChatGPT, or other MCP clients. The soundboard has 48 sounds, works without signup, and supports keyboard shortcuts for its first ten pads. The Free plan includes browsing and previews but no API access. Pro is $15/month or $150/year, and Enterprise is $49/month or $490/year; both include unlimited downloads, with different daily API request limits.
