The USB-C analogy is the one that sticks. MCP standardized the plug, not the power grid. That's not a flaw — it's a scope decision. But most teams discover the gap at 2 AM when an agent calls a tool it shouldn't have and there's no audit trail to answer "who did that." The virtual MCP server pattern is the fix because it moves governance from "trust the agent" to "configure the gateway." Allowlists over prompts every time. Prompts are suggestions. Allowlists are physics.
