In the context of MCP, what does the "USB-C for AI" analogy emphasize?

The "USB-C for AI" analogy is used in the Model Context Protocol (MCP) specification to illustrate its foundational purpose: providing a single, standardized interface for connecting AI models to external tools and data sources. Just as USB-C replaced fragmented, proprietary physical ports with a universal physical connector for hardware, MCP replaces custom, fragmented API integrations with a standard open protocol for software context exchange. This standardization enables AI applications to seamlessly connect with any compatible MCP server without writing custom glue code for every distinct backend service or database, thereby promoting interoperability across the entire AI ecosystem.

A. MCP is a software integration protocol and does not physically accelerate hardware execution speeds.
B. MCP is an open-source software standard framework, not software preinstalled on computer operating systems.
D. MCP operates entirely at the software application level without requiring specialized hardware devices.
