AI agents call local.pois to retrieve information from Earch MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about points of interest using location IDs. It performs a read-only query operation against local business data without any side effects, data modification, or external state changes. The low severity reflects that misuse would only expose publicly available local business information without enabling harmful actions.
From the tool's definition Tool description states 'fetch extra info for up to 20 location ids' - a retrieval operation with no modification or deletion of data.
