getHarmonizedSystem

// WHEN AI AGENTS USE THIS TOOL

AI agents call getHarmonizedSystem to retrieve information from Comexstat Data Server (Brazilian foreign trade statistics) without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

// WHY ENFORCE A POLICY ON GETHARMONIZEDSYSTEM

Even though getHarmonizedSystem only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

// RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.
