What is the Retell AI MCP Server?

Connect your Retell AI account to any AI agent and take full control of your conversational voice orchestration through natural conversation. Retell AI provides a premier platform for building human-like voice agents, and this integration allows you to create agents, initiate phone or web calls, and monitor LLM configurations directly from your chat interface.

What you can do

  • Agent & Persona Orchestration — List all managed voice agents and retrieve detailed persona metadata, including creating new agents programmatically.
  • Call Lifecycle Management — Initiate and monitor real-time phone or web calls and retrieve detailed call metadata including recordings and transcripts directly from the AI interface.
  • LLM & Brain Control — Access and monitor your Retell LLM configurations to ensure your agents always have the correct logic and knowledge via natural language.
  • Phone Number Intelligence — List available phone numbers to maintain a clear overview of your telephony infrastructure.
  • Operational Monitoring — Track system responses and manage agent settings using simple AI commands to ensure your voice operations are always optimized.

How it works

1. Subscribe to this server
2. Enter your Retell AI API Key from your dashboard settings
3. Start managing your voice agents from Claude, Cursor, or any MCP-compatible client

No more manual call logs or complex agent configuration. Your AI acts as a dedicated voice operations manager or AI lead.

Who is this for?

  • AI Developers & Product Managers — quickly retrieve call details and monitor agent performance without switching apps.
  • Customer Support Operations — automate the management of voice personas and track call history via natural conversation.
  • Operations Teams — streamline the retrieval of agent metadata and monitor organizational voice health directly within the chat.
