First Dollar — teach your agent to spend its own money

principle

Teacher, not butler.

First Dollar explains; the agent acts. The MCP never holds keys, never signs, never transacts. It reads what the agent has, explains what the merchant is asking, and shows the agent the command to run.

The agent spends its own money with understanding.
