    What is MCP?

    Model Context Protocol

    MCP (Model Context Protocol) is an open standard that enables AI assistants like Claude, ChatGPT, and others to interact with external tools and services. Think of it as a bridge between AI and the real world.

    With the ONCE MCP server, your AI assistant gains the ability to:

    • Create and manage music releases through natural conversation
    • Access your full catalog with context for smarter recommendations
    • Automate repetitive distribution tasks with AI-powered workflows
    • Monitor release status and delivery across all platforms

    This is the future of music distribution AI, where complex workflows become simple conversations.
