How to Use the AT&T Messaging MCP in VS Code Copilot

Q: How do we configure AT&T Messaging for our entire team in VS Code Copilot?

Add the server configuration to a .vscode/mcp.json file in your project's root directory. Once you commit and push that file, everyone who pulls the repo will have the AT&T Messaging tools available in Copilot.

Q: How do I check inbound replies with AT&T Messaging from VS Code Copilot?

Use the getinboundmessages tool. Your Copilot agent will fetch the latest messages sent to your shortcode, showing you the sender, keyword, and message body right in the chat panel.

Q: What if I need to send a picture message for a marketing campaign?

Use the sendmms tool. Just tell your Copilot agent the recipient's number, the text, and a public URL for the image you want to send. It's a simple way to test rich media campaigns.

Shared Messaging Tools for Your Team

Set up the AT&T Messaging tools once in your project's `.vscode/mcp.json` file and commit it to your repo. Now, every developer on the team gets the same capabilities in their Copilot chat automatically. No individual setup, no configuration drift. When your backend team needs to send a transactional SMS, they can use the exact same `send_sms` tool as the frontend team uses for testing a notification UI. This is the advantage of a shared MCP configuration.

Send Real SMS from Copilot Chat

You're working on a feature that sends an alert. Instead of running a separate script, just open Copilot Chat and tell it to use `send_sms` with a test number. You get an immediate message ID and delivery status without leaving VS Code. If a message fails, you can debug right there. Give Copilot the message ID and ask it to run `get_message_status`. It gets the failure reason from the AT&T API, helping you fix the bug much faster than digging through logs.

Manage Production Campaigns in VS Code

This isn't just for local dev. Your ops team can use Copilot to manage production campaigns. Ask your agent to provision a new campaign number with `create_shortcode` or decommission an old one with `delete_shortcode`. For compliance, have your agent run `list_messages` to pull an audit trail of recent sends and receives. Because the MCP server configuration is managed and shared, you know everyone is working with the right production environment.

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
