WHAT IT DOES

What query_business_data does on Small Business MCP Server

WHY IT NEEDS A POLICY

Why query_business_data needs a policy

A natural language query interface over business data systems is effectively arbitrary query execution. The tool translates unstructured input into data system operations, which could range from simple reads to complex queries with side effects. Since the underlying query scope is unbounded and the description is minimal, this is best classified as Execute.

From the tool's definition 'Query business data using natural language' — natural language interface to business data queries implies arbitrary query execution, potentially including destructive or sensitive operations depending on underlying data system
