Obtém dados climáticos usando coordenadas geográficas
AI agents call get_weather_by_coordinates to retrieve information from MCP Weather 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 information based on geographic coordinates. It has no capability to modify, delete, or execute operations—it only retrieves data from the OpenWeatherMap API. The read-only nature and lack of side effects make it a Read category risk with low severity.
From the tool's definition Tool retrieves weather data using geographic coordinates; function name contains 'get_' prefix indicating data retrieval; description states 'Obtém dados climáticos' (obtains climate data) without any modification or side effects

Register the MCP Weather Server MCP server in PolicyLayer and add a rule for get_weather_by_coordinates: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Weather Server. Nothing to install.
get_weather_by_coordinates 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_weather_by_coordinates 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.
Set action: deny in the PolicyLayer policy for get_weather_by_coordinates. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
