Get weather forecast for a location.
AI agents call get_forecast to retrieve information from MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns weather forecast information for a specified location. It is a read-only operation with no side effects, no code execution, no data modification, and no destructive or financial impact. The only minor risk is that an agent could spam requests, but this is mitigated by typical rate limiting and has minimal security implications.
