capture_document_pages
AI agents call capture_document_pages to retrieve information from Auto-Snap MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming and context within a screenshot/document automation server, this tool appears to capture or retrieve document page images. This aligns with Read operations (retrieves data with no side effects). Severity is low because capturing pages creates no destructive, financial, or execution risks.
From the tool's definition Tool name 'capture_document_pages' and server purpose of 'screenshot capture and document processing' suggest image/data retrieval. However, description is empty, limiting confidence.
