# GCS Media Storage

> GCSMediaStorage stores agent media in a Google Cloud Storage bucket.

`GCSMediaStorage` stores agent media in a Google Cloud Storage bucket and keeps only a `MediaReference` in the database.

<Snippet file="media-storage-gcs-params.mdx" />

`AsyncGCSMediaStorage` takes the same parameters and runs each call in a worker thread.

<Note>
  Signing needs a credential that carries a private key, from `credentials_path` or a service-account JSON on `GOOGLE_APPLICATION_CREDENTIALS`. Application-default credentials carry only a token, so `get_url` returns `None` and readers stream the bytes through `download` instead. `public=True` skips signing and always returns a URL.
