Perplexity

Claude Desktop reads your call history.

Your AI client pulls recent interactions instantly. You don't have to hunt through a CRM to find out what happened on yesterday's call. It uses `list_calls` to pull the log and `get_call_details` to grab the specifics of a single conversation. The same applies to text messages. If a customer texts your support line, Claude uses `list_messages` to read the thread and `send_message` to draft and fire off a reply right from the chat interface.

Manage contacts and team usage.

Support teams live and die by accurate contact data. This MCP Server lets your agent pull up customer records using `get_contact` or search the whole directory with `list_contacts`. You get the context you need before answering a question. When a new lead texts in, the AI can use `create_contact` to save their details immediately. It can also check who is online to handle an escalation by running `list_team_users`.

Audit your phone system configuration.

Phone system administration usually means clicking through ten different settings pages. Now, you just ask Claude. The `list_account_numbers` tool returns every provisioned phone number in your account. You can also check your backend integrations. The `list_webhooks` tool shows exactly where your call data is being routed, and `get_account_profile` confirms your current plan limits.
