WHAT IT DOES

What payware_utils_format_json_deterministic does on Payware MCP Server

AI agents call payware_utils_format_json_deterministic to retrieve information from Payware MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why payware_utils_format_json_deterministic needs a policy

Even though payware_utils_format_json_deterministic 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.
