JustCall MCP Server

by saaslabsco

Let an assistant make calls, send SMS and WhatsApp, and manage contacts and campaigns through a JustCall account.

Telephony, SMS & Voice Agents
Summary
A working phone line and messaging stack an agent can operate, backed by a real JustCall account.

The tool set spans the whole JustCall surface — voice, SMS, WhatsApp, contacts, campaigns, and analytics — so an agent can, for example, look up a contact, send an SMS, and check for the reply, or read the AI analysis of a finished call, all through one connector.

What it is

A remote MCP server that puts JustCall's telephony API behind tools, so an AI agent can place and manage calls, send messages, work contacts, and read analytics — turning a chatbot into something with a phone number.

What you get
  • Calls: list_calls, get_call, update_call, get_call_journey, and voice-agent call tools
  • Messaging: send_sms, list_sms, check_sms_reply, SMS tag and thread tools, plus WhatsApp send/list/template tools
  • Contacts and CRM: list_contacts, create_contact, update_contact, blacklist and DND controls; users, phone numbers, appointments, and webhooks
  • Sales Dialer: campaign create/update, campaign contacts, bulk import, and agent and account analytics; AI analysis tools return call and meeting transcripts and summaries
Requirements

A JustCall account and its API key and secret; the server is a hosted endpoint you connect to over OAuth, so there is nothing to install.
