§ The Protocol Stack
Three peer protocols. No hierarchy implied.
MCP is the machine-context layer. HCP is the human-context layer. VCP is the value-creation layer — what creates value, for whom, and why. They are peers because each addresses a layer the others do not reach. This page indexes the three; the bodies live on their own homes.
-
MCP Model Context Protocol
The machine-context layer. How AI systems reach tools, data, and external context — capability surfaces that make models operate against arbitrary software substrates.

VCP Value Creation Protocol
The value-creation layer. What creates value, for whom, and why — the operating methodology that translates capability and context into realized outcomes across customer, operations, and finance.

HCP Human Context Protocol
The human-context layer. How AI systems represent and respect human intent, authority, preferences, and history — so capability never gets aimed at the wrong audience.

VCP is originated and canonically implemented by Value-First Team. Anyone may read, cite, and operate the protocol independently of firm engagement.
