description = "The energy-native MCP gateway: a JCP enforcement point in front of an MCP server. Every tools/call is gated by a capability grant, the upstream call is metered (on the upstream server's own process tree where the host's kernel counts per-process CPU energy, and otherwise machine-wide: a hardware reading where the host exposes a live energy counter, an estimate where it does not, each sealed as what it is), the metered joules are debited from the grant's budget, and the decision seals into a hash-chained receipt log. The chokepoint position the AI-gateway field occupies — denominated in joules, with a tamper-evident audit, not dollars and a span."
