List all currently loaded PDF files.
AI agents call list_loaded_pdfs to retrieve information from PDF Redaction 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 retrieves metadata about loaded PDFs without side effects. It performs a simple read operation to display information about the current state of the server's loaded files. No data is modified, executed, or destroyed. The low severity reflects minimal risk even if an AI agent calls this tool — it merely queries existing state.
From the tool's definition Tool name 'list_loaded_pdfs' and description 'List all currently loaded PDF files' indicate a query/retrieval operation with no modification or deletion of data.
