Get current weather conditions for a specific location
AI agents call get_current_weather to retrieve information from Open Meteo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns weather data without side effects. It retrieves information about current atmospheric conditions, which is a read-only operation. No data is created, modified, deleted, or financial transactions are involved. The blast radius of misuse is minimal—an agent could only retrieve weather information for arbitrary locations, which poses no security or operational risk.
From the tool's definition Tool name is 'get_current_weather' and description states 'Get current weather conditions for a specific location' — a retrieval operation with no modification, deletion, or execution of external commands.

get_current_weather is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_current_weather rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
