Connect Grok Bot to UserAlertX (MCP connector)

UserAlertX runs a hosted MCP server that Grok Bot can call directly as a custom connector — no code, no webhook to hand-write. This is a good fit if your Bot already needs other tools/connectors alongside this one. Just want the absolute simplest setup with nothing to configure in Grok Bot's settings? See the email trigger instead — it's genuinely zero-config.

1. Get your UserAlertX API key (one-time)

  1. Go to useralertx.com/getstarted.html and enter your email.
  2. Click the confirmation link that arrives by email.
  3. The confirmation page shows your api_key exactly once — copy it now.

2. Add UserAlertX as a custom connector in Grok Bot

  1. In Grok Bot, go to Settings → Plugins (or grok.com/connectors → New Connector).
  2. Choose Custom.
  3. Server URL: https://useralertx.com/mcp
  4. Auth header: Authorization: Bearer YOUR_API_KEY (paste the key from step 1 in place of YOUR_API_KEY)
  5. Save. Grok Bot will discover one tool: send_sms_to_me.

3. Use it

Tell your Bot something like: "When this job finishes, text me via UserAlertX." It calls send_sms_to_me with the message body — nothing else to configure.

First use may come back held, not sent yet — that just means your phone hasn't confirmed opt-in on this number yet. You'll get a one-time text asking you to reply Y; after that, every future alert goes straight through.

What this connector can and can't do

Toolsend_sms_to_me(body) — one tool, nothing else exposed.
DestinationAlways the one phone/email you verified on your own UserAlertX account. There is no recipient parameter — it structurally cannot text anyone else.
Your keySent once per request as a Bearer token, straight through to UserAlertX's existing send API — the same auth path any other integration uses. Never stored by this connector beyond the request.
ErrorsRate limits, opt-out, and free-tier limits all come back as a plain-language message the Bot can relay to you directly.
