MCP enables integration between language model applications and external data sources and tools. MOQT provides publish-subscribe delivery over QUIC and WebTransport with native prioritization, relay caching, and multiplexing. This specification maps MCP messages onto MOQT objects and defines procedures for session establishment, capability discovery, and ongoing communication. It covers MCP's core primitives (resources, tools, prompts, sampling, and notifications) through dedicated MOQT tracks. The document also describes Agent Skills -- composed instructions that extend AI capabilities beyond atomic tool operations -- using progressive loading aligned with MOQT's object-based delivery.
