Get Server Information.
AI agents call get_server_info to retrieve information from Nest Protect 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 or queries server metadata/status information without side effects. It falls squarely into the Read category as it only provides information about the server's state, configuration, or capabilities. The low severity reflects minimal blast radius—misuse would only expose metadata, not control device behavior or compromise safety systems.
From the tool's definition Tool name 'get_server_info' and description 'Get Server Information' indicate a data retrieval operation with no modification, deletion, or execution of external operations.
