AI agents call classify-document to retrieve information from Pdf without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes and categorizes PDF documents without modifying them or triggering external operations. Classification is a passive analysis operation that reads document properties/content and returns categorization results. The lack of any destructive, write, execute, or financial keywords, combined with the read-only nature of PDF processing servers, places this firmly in the Read category with low severity.
From the tool's definition Tool name 'classify-document' and description indicate document classification (categorization of existing content).

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