## About Carbon Voice MCP with LuumenAI

Carbon Voice holds a lot of decisions that never made it into a ticket. Luumen reads your authorized voice messages, conversations, folders, and AI Action responses to pull that context into the terminal. When something needs to go back out — a reply in a thread, a direct message, a new folder — it previews the change first and waits for your approval. Connection uses DCR OAuth.
