get_asset_downloads

Get five-minute private GET URLs for up to 16 media IDs; no bytes. preview=true prefers small images. Fetch without Authorization/cookies. Keep URLs secret; store stable media IDs, not temporary URLs. Details: /docs/mcp/get_asset_downloads.

Authorize up to 16 immutable media IDs in one request and return compact five-minute private R2 GET URLs, never media bytes. Example: {boardId:'board',ids:['<64 lowercase hex>'],preview:true}. Fetch returned URLs over HTTPS without cookies or Authorization. preview=true prefers a persistent small image; variant reports whether it is a preview or original. Omitted/missing IDs have no result. URLs are temporary bearer capabilities: do not publish them; keep the stable info.src/id in document parts. Refresh this request after expiry. Viewer/read access is sufficient.
