get_current_weather
AI agents call get_current_weather to retrieve information from MCP Server Template without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves current weather information with no side effects, falling squarely into the Read category. The empty description slightly lowers confidence, but the naming convention clearly indicates a query/fetch operation. Severity is low as weather data access poses minimal risk even if misused by an AI agent.
