Retell AI is a platform for building, deploying, and monitoring AI voice agents for phone calls, web calls, chat, and SMS. It provides tooling for agent creation, telephony, testing, analytics, and related workflow integrations.
Retell AI exposes a Bearer-token REST API plus a hosted Streamable HTTP MCP server that supports API-key auth and curated-registry OAuth; docs also publish official Node.js and Python SDK packages built on the same API key auth.

In the Retell dashboard, open the API Keys tab to create or copy a workspace API key. The docs say API keys authenticate Retell REST API requests, SDK integrations, and MCP usage, and REST requests send it as Authorization: Bearer YOUR_API_KEY. Manage scopes from Manage API keys and permission scopes.
Connect your MCP client to Retell's hosted MCP server at Retell MCP server docs. The curated registry marks the MCP endpoint as OAuth-enabled. In OAuth-capable MCP clients, add the server endpoint and complete the Retell sign-in/consent flow when prompted. Retell's docs also describe API-key-based MCP auth for other clients.
