Introduction

​

What you can build

• Read — pull calls, transcripts, leads, bookings, and insights for reporting, CRM sync, or your own UI.
• Write — add FAQs, update agent personality, move leads through a pipeline, schedule appointments.
• Listen — subscribe to webhooks for emergency transfers, new leads, booked appointments.
• Agentic — point Claude, ChatGPT, or Cursor at our MCP server and let AI do everything on behalf of the user.

• REST with Bearer token — phones masked, transcripts/recordings only with explicit scopes, billing hidden entirely.
• MCP tools/call — same scrubbing as REST.
