## Why get_tariffs is rated Low

This tool queries and retrieves energy tariff information filtered by postal code. It has no side effects—it only reads and returns existing tariff data from a database. While affiliate links are included, the tool itself does not execute financial transactions or commit obligations. The primary function is data retrieval for comparison purposes, which is characteristic of Read operations.

From the tool's own definition: "Tool retrieves real-time tariff data and pricing information ('Real-time German tariff database', 'Provides current prices'). No modification, deletion, or financial transaction capabilities described."

## Use case

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