WHAT IT DOES

What dex_execute_swap does on VeChain AI Terminal MCP Server

AI agents invoke dex_execute_swap to trigger actions in VeChain AI Terminal MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why dex_execute_swap needs a policy

dex_execute_swap triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
