- Delivery Status -- Check real-time delivery state (sent, delivered, failed, read) for any message by its ID
- Message History -- Query outbound and inbound message logs for auditing, compliance reporting, or reply tracking
- Inbound Messages -- Retrieve customer replies, opt-outs, and keyword-triggered auto-responses
- Shortcode Management -- Provision new shortcodes with keywords for campaign routing, or decommission retired numbers

Frequently asked questions
What sender IDs can I use to send SMS messages?
You must use a registered AT&T shortcode or dedicated long code as the sender ID. Unregistered or random numbers will be rejected by the carrier. You can provision new shortcodes with keywords using the create_shortcode tool, or check your existing ones through the messaging dashboard. Each shortcode can be configured with multiple keyword auto-responses.
Can I send MMS with images and what formats are supported?
Yes. The send_mms tool accepts a publicly accessible media URL. Supported formats include JPEG, PNG, GIF for images, MP4 for video, and common audio formats. The media URL must be reachable by AT&T's servers -- local or private URLs will fail. Maximum file size limits apply per carrier specifications, typically up to 1MB for images and 3.5MB for video.
How do I handle customer opt-out requests like STOP?
AT&T Messaging automatically processes standard opt-out keywords (STOP, CANCEL, UNSUBSCRIBE, QUIT). When a customer sends one of these, they are added to your suppression list and will no longer receive messages from that shortcode. You can monitor inbound messages with get_inbound_messages to track opt-out activity and verify your keyword configuration with get_keyword_responses.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
