Perplexity

Direct outbound calling from your chat

The FreeClimb MCP Server hooks directly into Claude Desktop so you can trigger outbound phone calls with `make_call` right from your chat input. Your agent reads live call metadata using `get_call_details` to verify if the recipient picked up, keeping you updated in the local sidebar. You don't need to jump back and forth between your terminal and a browser dashboard. Just tell Claude Desktop to dial a number, and it manages the active session on your machine using stdio transport.

Instant SMS dispatch and log monitoring

This integration lets you send text messages using `send_sms` and track delivery status with `get_sms_details` inside Claude Desktop. Your agent monitors incoming replies by polling `list_sms_messages` to handle two-way conversations without custom webhook code. Setting up this MCP Server connection takes less than two minutes. Once you save the config file, Claude Desktop immediately gains the ability to read your SMS logs and flag failed deliveries.

Live phone number provisioning

You can search and buy new phone numbers using `list_buyable_numbers` directly from the Claude Desktop interface. Your agent registers these numbers to your account and maps them to your communication apps using `list_applications`. Instead of navigating the FreeClimb portal, you tell Claude Desktop to find a local area code and buy it. The agent executes the setup, lists your active inventory with `list_my_numbers`, and displays the live account balance using `get_account_status`.
