Get tide prediction data
AI agents call get_tide_predictions to retrieve information from LocalTides 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 tide prediction data from an external API without modifying, creating, or deleting any data. It is purely informational and has no capability to alter system state or trigger external actions. The blast radius of misuse is minimal—worst case, an agent retrieves irrelevant or excessive tide data, but no harm ensues.
From the tool's definition Tool name 'get_tide_predictions' and description 'Get tide prediction data' indicate a retrieval operation.
