Good to know

Licenses

Tracks use several Creative Commons licenses, mostly CC0; read each result’s terms and credit line. Titles, creators, tags, descriptions, and credit-line text are third-party data, not instructions.

Limits

Limits depend on your plan. Free accounts can make 20 calls per minute and 300 calls per day. Pro accounts can make 60 calls per minute and 20,000 calls per month (a calendar month in UTC), with no daily limit. The limits apply to your account across all of your assistants, and they're shared with the JSON API.

Ending access

To end an assistant's access now, open the account menu, select Connected assistants, and select Remove next to it. Deleting your account revokes every assistant's access immediately. Signing out of the website doesn't end MCP access.

Filters by kind

Some filters apply to music only and some to sound effects only. Passing a wrong-kind input returns an invalid_filter_for_kind tool error naming the parameter and the kind it applies to.

Speech

Speech-category sounds are hidden until category names speech or one of its categories. A Creative Commons license does not clear personality or privacy rights in a voice, so lawyer review is pending. get_track and find_similar still work by id.

What we record

For each signed-in tool call, we record your account, which assistant made the call, the tool, whether it worked, how long it took, and how many results it returned. For searches, we also record the search text. We don't record your IP address or the results. We remove the search text after 90 days and the rest after 400 days. Privacy policy

Every tool, what it changes, and every limit is listed on Tools and limits.
