Text Grok Bot from your phone, and get texts back

Ask Grok Bot to add AI Text-a-roo as a custom MCP server, then sign in with your phone number. Grok Bot can then text you. To text it back anytime, ask Grok Bot to create a webhook routine and register it with AI Text-a-roo's set_webhook tool: each text you send then wakes the bot.

Method: Custom MCP server + webhook routine · Updated October 24, 2026

Set up Grok Bot

  1. 1

    In a Grok Bot chat, say:

    Copy
    Add a custom MCP server called AI Text-a-roo at https://api.aitextaroo.com/mcp
  2. 2

    Sign in with your phone number and the 6-digit code when Grok Bot asks you to authorize. We'll text you that the app is connected.

  3. 3

    So you can text Grok Bot anytime, ask it to set up forwarding:

    Copy
    Create a webhook routine that reads my text from AI Text-a-roo's webhook and replies with send_text. Then register the routine with AI Text-a-roo using set_webhook.
  4. 4

    If you've set a security PIN, Grok Bot asks you for it. AI Text-a-roo then texts you where your texts are going. Text UNHOOK anytime to stop forwarding, or stop it on your dashboard.

  5. 5

    Text your AI's number. Grok Bot wakes up, does the work, and texts you back.

Things to ask Grok Bot

  • “When I text you, treat it like a chat with me and reply by text.”
  • “Every morning, check my calendar and text me anything I need to prepare for.”
  • “If I text “status”, reply with what you're working on.”

Good to know

  • Grok Bot's computer hibernates when idle, so a background bridge process isn't a good fit. Use the MCP server and a webhook routine instead.
  • Webhook routines accept up to 200 runs per hour each.
  • xAI says Grok Bot supports the same MCP servers, plugins and skills as Cursor. You can also ask it to create a skill from our SKILL.md.

Grok Bot FAQ

Does Grok Bot have SMS built in?

No. Grok Bot doesn't have its own SMS channel. AI Text-a-roo adds one: outgoing texts through the MCP server, and incoming texts through a webhook routine that wakes the bot.
