Check if a specific book is available for borrowing.
AI agents call check_book_availability to retrieve information from UAAR University MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries the library system to retrieve information about book availability. It has no side effects, does not modify data, does not execute code, and does not perform destructive or financial operations. It is a simple read operation consistent with library catalog lookup functionality.
From the tool's definition Tool name 'check_book_availability' and description 'Check if a specific book is available for borrowing' indicate a query operation that retrieves availability status without modifying data or triggering external operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and UAAR University MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for check_book_availability:
{
"version": "1",
"default": "deny",
"tools": {
"check_book_availability": {}
}
}check_book_availability is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
