## Description

The RetellAI MCP server provides AI assistants with direct access to RetellAI's voice services for creating and managing phone conversations. Built by abhaybabbar, this implementation exposes tools for call management, agent configuration, phone number provisioning, and voice selection through the Model Context Protocol. The server connects to RetellAI's API using a provided API key and transforms requests and responses between MCP format and RetellAI's native format. It's particularly valuable for applications that need to initiate outbound calls, handle inbound calls, or create voice agents with specific personalities and capabilities for tasks like automated customer service, appointment scheduling, or information gathering.
