Grok Bot + AgentLine

Give Grok Bot its own phone number

How do I give Grok Bot a phone number?

Send Grok Bot one prompt: "Read https://agentline.cloud/skill.md and set yourself up with an AgentLine phone number." Give it your AgentLine API key through a secure prompt, approve the number, and it can place calls, answer inbound calls, and send and receive texts from its own US or Canada number. Plans start at $20 a month with the number, 100 minutes and 400 texts included.

01
Create an AgentLine account at https://agentline.cloud/signup and copy your API key. Your first number starts a 7-day free trial.

Send Grok Bot the setup prompt. When it asks for the key, paste it into the secure prompt or the Vault, not the chat.

Read https://agentline.cloud/skill.md and set yourself up with an AgentLine phone number. Ask me for the API key in a secure prompt, never in chat. Confirm the cost with me before you buy the number.

03
Test it on your own phone: "Call me at +1... and tell me you're set up. Then text me a one-line summary."

Grok Bot is xAI's AI teammate with its own cloud computer. AgentLine gives it a dedicated US or Canada number: it can place calls, answer inbound calls around the clock, and send and receive texts, with a transcript for every call. Setup is one prompt: Grok Bot reads the AgentLine skill and wires itself up.

Get an API key

One skill file

Grok Bot sets up tools by reading their docs, so the skill file is the whole install. Point it at https://agentline.cloud/skill.md, give it the API key through a secure prompt, and approve the number purchase.

Why give Grok Bot a phone number

A number the bot owns

Grok Bot gets its own E.164 number for callbacks and texts. It never borrows your cell, and people can call or text it back.

Inbound calls and texts, 24/7

The hosted AgentLine agent answers calls while Grok Bot's computer sleeps. Inbound texts arrive as sms.received events the bot reads later.

One prompt to set up

Grok Bot reads skill.md and configures itself. No SIP trunk, no Twilio account, no connector to build.

Set up Grok Bot

How the skill and the service land on this runtime.

1. Store the API key

Give the key to Grok Bot through its secure prompt or Vault so it lands in the environment of Grok Bot's cloud computer. Never paste it into the chat.

bash

export AGENTLINE_API_KEY="al_live_..."

2. Optional: add the MCP server

If you prefer tools to the skill, ask Grok Bot to add the AgentLine MCP server to its MCP settings. Placing calls, buying numbers and reading transcripts then become tool calls you approve. Sending SMS stays on the REST API (POST /v1/messages).

  "mcpServers": {
    "agentline": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://api.agentline.cloud/mcp", "--header", "Authorization: Bearer $AGENTLINE_API_KEY"]
    }
  }
}

3. Optional: route live calls through Grok Bot

AgentLine's hosted voice agent answers calls on its own, even when your laptop is closed. To have Grok Bot's own context answer mid-call questions, install the relay on its cloud computer. --handler must be a shell command that reads the caller's message on stdin and prints the reply.

bash

python -c "import urllib.request; urllib.request.urlretrieve('https://api.agentline.cloud/static/agentline_relay.py','agentline_relay.py')"
python agentline_relay.py install --agent-id agt_xxx --runtime custom --handler "YOUR_HANDLER_COMMAND"

FAQ

Can Grok Bot make phone calls?

Yes. Since Grok Bot 0.77 (October 2026) it can place calls on your behalf, wait on hold, press keys and send you a summary. To give it a dedicated number that people can call back and text, connect a phone provider: AgentLine does it with one prompt that points Grok Bot at https://agentline.cloud/skill.md.

What is Grok Bot?

Grok Bot is xAI's AI teammate app for macOS, Windows and iOS. Each bot works on a persistent cloud computer, signs in to your tools, runs routines on a schedule, and can be extended with skills and marketplace templates.

Can Grok Bot receive calls and texts?

With an AgentLine number, yes. The hosted AgentLine voice agent answers inbound calls 24/7 and saves a transcript. Inbound texts arrive as sms.received events, and Grok Bot sends texts with POST /v1/messages. Grok Bot can read every transcript and message through the API or MCP server.

How is this different from the dial bot in the Grok Bot Marketplace?

The marketplace dial bot places outbound calls through a Bland AI account. Bland's Agent Phone Plan is $14.99 for the first month, then $29.99/month, one call at a time, with fair-use caps (checked 2026-10-30). AgentLine plans start at $20/month with a number, 100 minutes and 400 texts, then $0.12/min, and you can add numbers for $3/month each.

How much does a Grok Bot phone number cost with AgentLine?

Plans start at $20/month and include a US or Canada number, 100 call minutes and 400 SMS. Beyond the plan, calls are $0.12/min billed per second after a one-minute minimum, texts are $0.02, and extra numbers are $3/month. Your first number starts a 7-day free trial. Grok Bot's own subscription is separate.

Will the agent say it is an AI on calls?

Put it in the prompt. Tell Grok Bot to have the voice agent say it is an AI assistant calling for you, to confirm the number and goal with you before dialing, and to honor any request to stop calling. AgentLine keeps a transcript of each call so you can check.

Is AgentLine affiliated with xAI?

No. This is an independent AgentLine integration guide. Grok and Grok Bot are trademarks of their owners.
