dex_build_swap · Logiqical MCP: Risk & Policy

WHAT IT DOES

What dex_build_swap does on Logiqical

AI agents invoke dex_build_swap to trigger actions in Logiqical. 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_build_swap needs a policy

While financially consequential, the tool itself does not move funds; it builds the transaction structure.

From the tool's definition Tool name 'dex_build_swap' and description 'Build unsigned swap transactions' indicate constructing and preparing blockchain transactions for execution.
