Audit Support Calls in Claude Desktop

The `list_calls` tool lets Claude Desktop pull your recent inbound and outbound call logs directly into your chat. You just ask your agent to find a specific interaction, and it grabs the exact timestamp, duration, and status without you opening another browser tab. Once you spot the interaction you want, your AI client uses `get_call` to grab the specific notes and participant details. If you need to check the actual audio for quality assurance, it fetches the link using `list_recordings` so you know exactly what your support rep said to the customer.

Read SMS Threads and Vet Contacts

You can read full text message conversations inside Claude by triggering the `list_messages` tool. This pulls the exact message content, sender details, and delivery status for your SMS and MMS campaigns. Before you reply or escalate a ticket, your agent runs `list_contacts` to find the customer. It then uses `get_contact` to pull their associated phone numbers, email addresses, and metadata so you have the full picture of who you are talking to.

Manage JustCall MCP Server Infrastructure

Pulling system metrics is built right into this MCP Server through the `list_campaigns` tool. Your AI client grabs live data on your active dialer campaigns and telemarketing efforts to see where your call volume actually originates. You also need to know who is handling that volume, so Claude runs `list_users` to identify which agent handled specific calls. If your integrations start failing, it checks your event routing by calling `list_webhooks` to audit your configured endpoints.
