Search the school
AI agents call search_assets to retrieve information from Crescender 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 data (school assets) without creating, modifying, deleting, or executing operations. The read-only nature of the server and the search operation itself confirm this is a Read category tool with low severity—worst case is information disclosure of asset data.
From the tool's definition Tool is described as part of a 'Read-only MCP server' and 'search_assets' performs a search operation with no mutation capability.
