dial-crewai

Official Dial tools for CrewAI — give a multi-agent crew the ability to send SMS, receive OTP codes, and place AI voice calls through Dial. Agents automating signups and web tasks get a real phone identity.

It's the CrewAI sibling of dial-langchain: each tool is a crewai.tools.BaseTool subclass wrapping the dial-sdk client. It adds nothing to the REST contract — it just shapes Dial's operations into CrewAI tools.

Install

pip install dial-crewai

This pulls in dial-sdk and crewai.

Give the tools to a crew

Build one DialClient, pass it to dial_tools, and hand the list to an agent. Every tool shares that one client — a single connection pool for the whole crew:

from crewai import Agent, Crew, Task
from dial_sdk import DialClient, DialConfig
from dial_crewai import dial_tools

dial = DialClient(DialConfig(api_key="sk_live_..."))

phone_agent = Agent(
    role="Phone identity agent",
    goal="Send and receive SMS so the crew can complete phone-verified signups",
    backstory="You operate the crew's Dial phone number.",
    tools=dial_tools(dial),
)

DialConfig also takes an optional base_url to target a non-default deployment.

Or pick individual tools

from dial_crewai import SendMessageTool, WaitForMessageTool

tools = [
    SendMessageTool(client=dial),
    WaitForMessageTool(client=dial),
]

Available tools

Each tool takes your shared DialClient (client=):

Tool Action
ListNumbersTool List your phone numbers
PurchaseNumberTool Provision a new number (billable)
SetNumberPropertiesTool Update a number's nickname / inbound instruction
SendMessageTool Send an SMS (optionally MMS)
ListMessagesTool List recent messages
MakeCallTool Place an AI voice call
ListCallsTool List recent calls
GetCallTool Fetch one call by id
GetBillingTool Credit balance, subscription, per-number mode
WaitForMessageTool Block until the next inbound SMS arrives, or time out

OTP flow

The point of phone identity for a crew: send a code and read the reply. WaitForMessageTool blocks until the next inbound SMS arrives, so an agent can:

  1. trigger a signup that texts a code to your Dial number,
  2. call WaitForMessageTool to read the inbound code,
  3. enter it back into the signup form.

See examples/signup_crew.py for a runnable crew.

Notes

  • The dial-sdk client is async; these tools are sync-first (_run) with an async→sync bridge, and also expose _arun for async crews. The shared client's requests run on a single background event loop, so the connection pool is reused across calls; a sync crew needn't close the client explicitly.
  • SendMessageTool is a write action and isn't idempotent — a re-invoke after a failure can send a duplicate. MakeCallTool accepts an idempotency_key.
  • WaitForMessageTool is backed by Dial's presence-based event stream — for durable, at-least-once delivery, register a webhook.

See the CrewAI integration docs for the full guide.
