Integrate AT&T Messaging with Claude, Cursor, Chatbots & AI Agents MCP Server

Q: 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 Vinkius protects your data

Is there a risk of the AI "going crazy" and deleting important company data?

No. With Vinkius, the AI operates on "rails". It can only make the exact moves you authorized in the tool's settings. It cannot invent routes, access other networks in your company, or decide to delete random files. If the action isn't in the approved catalog, the attempt is blocked instantly.

Can I set different limits for each virtual assistant on my team?

Absolutely. You have full control in our command center. You can create an AI agent that only "reads" data so the support team can answer questions, and another superpowered agent that can "edit" and "create" information exclusively for your operations team. Each AI gets exactly the level of access you allow.

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.

What if the AI ends up reading customer data or confidential information?

We have a built-in digital "bodyguard" called DLP (Data Loss Prevention). If a tool fetches data and the response contains social security numbers, credit cards, or personal customer info, Vinkius magically blocks and erases that information before it is delivered to the AI. The AI works only with what is strictly necessary, and your sensitive data never leaks.

What can AI Agents do with AT&T Messaging?

We map standard API endpoints to agent-compatible instructions. Connect AT&T Messaging to execute these core functional operations.
