WHAT IT DOES

What list_supported_currencies does on MCP Framework Personal

AI agents call list_supported_currencies to retrieve information from MCP Framework Personal without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_supported_currencies is rated Low

Even though list_supported_currencies only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

list_supported_currencies Allowed

list_supported_currencies is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
