Can this MCP handle both SMS and MMS?

Yes. You can send standard SMS messages using the send_sms capability, and you can also send rich MMS messages that include media attachments using the send_mms capability.

Does it help me track if a message was actually delivered?

Absolutely. You can use the get_message_status capability to check the real-time delivery state for any message ID, confirming if it was sent, delivered, or failed.

Can I manage my shortcodes through this MCP?

Yes. You can provision new shortcodes with keywords using create_shortcode, or decommission old ones using delete_shortcode.

How do I review customer replies or opt-outs?

You use get_inbound_messages to retrieve recent customer replies, which helps you monitor engagement and process STOP/START commands.

Is this good for compliance and auditing?

Yes. The list_messages capability allows you to query comprehensive message history, providing timestamps, sender, and content snippets for full auditing.

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 capability, 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 capability 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.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Real work

What teams actually run

Order Confirmation Alerts

Flash Sale Broadcasts

You use send_bulk_sms to send a time-sensitive promotion to thousands of customers simultaneously.

Opt-Out Management

The agent retrieves customer replies using get_inbound_messages, allowing you to confirm if a customer sent a STOP command.

Compliance Reporting

You query the full message history using list_messages to generate an audit trail of all communications for a specific date range.

Automate a task

Put AT&T Messaging to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

AT&T Messaging works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put AT&T Messaging to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
