extract_pdf_images
AI agents call extract_pdf_images to retrieve information from PDF Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Extracting images from a PDF is a query/retrieval operation that does not modify, delete, execute code, or create financial obligations. The worst-case misuse is unauthorized access to embedded images, which has limited blast radius compared to write, execute, or destructive operations. Low severity reflects the read-only nature and minimal direct harm potential.
