We are investigating delayed MMS delivery to AT&T destinations. Messages are being delivered, but with delays. SMS to AT&T and MMS to other carriers are unaffected. We are working with our downstream partner to identify the cause of the delay.

Follow Telnyx

Your coding agent knows when Telnyx is down, and tells you when a failure is theirs, not yours. You can also get Telnyx incidents in a feed reader or in Slack.

Prompt
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.

Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.

Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "telnyx" and tell me if Telnyx has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.

Paste this into any coding agent. It adds the server with its own MCP setup.
