A Connector is a URL. Vinkius runs it: hosting, security, governance, observability.
You're looking at one of 5,800+ managed Connectors. The real value isn't the catalog. It's the control plane that secures, governs, audits, and manages every interaction between your agents and the tools they use.
No Shadow AI
Every agent action is visible, approved, and auditable. Nothing runs outside your governance.
Absolute agent control
Fine-grained permissions for every agent, MCP, and tool. Instantly revoke access and audit every execution.
Cost control per token
Spend broken down to the token, tool, and agent. Budgets and hard limits. No surprise invoices.
Managed & monitored infra
We operate the runtime, authentication, scaling, retries, and monitoring. Your team manages AI, not infrastructure.
Data protection, DLP by design
Sensitive data is filtered before reaching the model. Access is governed so agents receive only the information they're allowed to use.
Token optimization, real savings
Lower AI costs by delivering the right context instead of unnecessary tools. Better accuracy, faster responses, and fewer wasted tokens.

Frequently Asked Questions
Can the AT&T Messaging MCP send images? +
Yes, you can send MMS messages with images, videos, or audio files using the send_mms tool. This allows your AI agent to handle rich media content for marketing or alerts.
How do I handle bulk sends with AT&T Messaging MCP? +
You can use the send_bulk_sms tool to send a single message to up to 164 recipients at once. Your AI agent will handle the batching and provide a status array for each recipient.
Can AT&T Messaging MCP help with compliance? +
Yes, it can. You can use list_messages to pull a full history of outbound and inbound messages, including timestamps and content snippets, which is perfect for auditing.
Does AT&T Messaging MCP support shortcodes? +
Yes, the Connector includes tools to provision new shortcodes with specific keywords and decommission retired ones. This makes it easy to manage multiple campaign numbers.
Can I check if an SMS was delivered using AT&T Messaging MCP? +
Yes, you can use get_message_status to check the real-time delivery state of any specific message by its ID. This helps you debug failed sends or track campaign success.
How do I see customer replies with AT&T Messaging MCP? +
You can use get_inbound_messages to retrieve recent customer replies, including the sender number, the keyword matched, and the message body.
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.
