Get current weather by coordinates using OpenWeatherMap.
AI agents call get_weather_by_coordinates to retrieve information from MCP Weather SSE Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves weather information based on geographic coordinates. It has no capability to modify, delete, or execute operations—it purely queries and returns data. The operation is read-only with no side effects on any system or data store. Severity is low because misuse would only expose publicly available weather information.
From the tool's definition Tool name 'get_weather_by_coordinates' and description 'Get current weather by coordinates' indicate a retrieval operation. The server is explicitly described as providing 'real-time weather data' and 'fetch[ing] current weather conditions'.
Attacks that exploit this kind of access
Get current weather by coordinates using OpenWeatherMap. It is categorised as a Read tool in the MCP Weather SSE Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Weather SSE 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 SSE 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.
get_weather_by_coordinates is provided by the MCP Weather SSE Server MCP server (tranducthai/mcp_protocol_for_llm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
