How to Use the AT&T Messaging MCP in Cursor

Q: How can I use AT&T Messaging to generate test data in Cursor?

Enable Agent mode and ask your agent to use a tool like sendsms. Cursor will execute the call, get a real message ID from AT&T, and you can tell it to use that ID in the code it's writing for you.

Q: Can I manage shortcodes from my code editor?

Yes. With this MCP server, you can use the createshortcode and deleteshortcode tools. Ask your agent in Cursor to provision or decommission numbers as part of the script you're writing.

Q: How do I check for inbound messages from AT&T Messaging inside Cursor?

Just ask your agent to run the getinboundmessages tool. It will fetch recent SMS/MMS replies, and you can use that live data to build and test your response handling logic on the spot.

Write code that sends real SMS messages. Connect Cursor to the AT&T Messaging API and stop using mock data.

Generate Code with Real Message IDs

Stop hardcoding fake message IDs or delivery statuses. In Cursor's Agent mode, you can ask your agent to send a test SMS using `send_sms`. It will call the AT&T API and inject the actual message ID right into your code. Now you can immediately write the next part of your function, like a follow-up call to `get_message_status` using that real ID. Your agent builds working, tested code from the start because it's interacting with the live service.

Scaffold Campaign Logic in Your Editor

You're building a new customer notification system. Instead of tabbing over to API docs, just ask your agent to provision a number with `create_shortcode`. It will add the call to your script and you can immediately start building logic around it. This MCP connection makes it fast. Need to handle replies? Have the agent use `get_inbound_messages` to pull a real customer message. Then ask it to write the parsing logic for you. You're building and testing your app's messaging flow without ever leaving the editor.

Test Bulk Operations from Cursor

Before you deploy your bulk notification script, you need to know it works. Use `send_bulk_sms` directly from Cursor to send a small test batch. The agent will return the job ID and the status of each recipient, so you can debug your code with real API feedback. Same goes for auditing. If you need to write a script for compliance reports, use `list_messages` to fetch a sample of the message history. Your agent can then use that live data to generate the exact code you need to parse and format the report.

Setup guide

Set up AT&T Messaging MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the AT&T Messaging MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent AT&T Messaging transactions." If the MCP tools are loaded correctly, Cursor will call the AT&T Messaging tools automatically. You can also check Settings → MCP for a green status indicator.
