Roleplays: How we wrote evals for the Hume MCP Server
We recently released the Hume AI MCP Server. This means if you that you can use Hume right from inside your AI chat using client applications — like Cursor or Claude Desktop — that implements the Model Context Protocol (MCP). You can use the AI to interactively help you with tasks like "can you help me narrate my audiobook?" or "can you help me design a voice for my video game character?". While it was previously possible to copy and paste between your favorite AI assistant and Hume, using Hume through MCP streamlines the process and can save you a lot of pointing and clicking.
