WHAT IT DOES

What authorize_tool_call does on Tenzro Ledger MCP

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

RISK

Why authorize_tool_call is rated Low

Even though authorize_tool_call 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.
