Get previous page of search results.
AI agents call search_pdf_prev_page to retrieve information from PDF Tools 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 and displays paginated search results from a prior PDF search operation. It performs no data modification, deletion, execution, or financial operation. The navigation of search result pages is a read-only operation with no side effects. Low severity is appropriate as misuse would only result in viewing information already accessible through the search function.
From the tool's definition Tool name 'search_pdf_prev_page' and description 'Get previous page of search results' indicate navigation through previously-retrieved search results without modifying data.
