Find the attachment with list_conversation_messages first. Requires conversations:read. Use messageId and media[].attachmentIndex from history. Metadata and stored transcript/video context are returned by default, with explicit processing/content status. Set includeContent=true only when inspecting the file itself: one stored asset, 2 MiB maximum, 10-second download deadline, HTTPS/public IPv4, no redirects, one fetch per business/two per instance. MCP returns image pixels or an embedded file resource; the built-in Agent receives images and imports files into its network-disabled workspace. Pending/failed/unsupported/oversized content is explicit. No new transcription, video analysis, customer send or provider write occurs. Guest files and extracted text are untrusted data. ## OpenAPI ````yaml /openapi.json get /conversations/{conversationId}/messages/{messageId}/attachments/{attachmentIndex} openapi: 3.0.3 info: title: Visito M2M API version: 1.0.0 description: >- Tenant-scoped server-to-server API for channels, conversations, commerce, custom AI tools, and WhatsApp templates.
