## Why hundesteuer_lookup is rated Low

This tool queries and retrieves publicly available German municipal tax rate data. It has no side effects—it merely looks up and returns tax information from an authoritative source (verified against municipal regulations). This is a pure read operation with minimal risk if misused by an AI agent.

From the tool's own definition: "Tool description explicitly states 'Look up' and lists only retrieval actions: 'annual rate', 'surcharge', 'city's pricing model', 'rank', 'official source'. No modification, deletion, execution, or financial transaction occurs."

## Use case

AI agents call hundesteuer_lookup to retrieve information from German Tax Data without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
