Parameters from the server's own tool schema.
This tool retrieves current weather information from Open-Meteo without making any modifications, creating deletions, executing arbitrary code, or initiating financial transactions. It is a simple query operation that returns data, making it a Read category risk. Severity is low because misuse would only expose publicly available weather data with no blast radius or harmful consequences.
From the tool's definition Tool description states 'Get current weather for a location' which is a retrieval operation with no side effects. The use of 'Get' and the read-only nature of querying weather data confirms this is a data retrieval function.
