Download a document file as base64-encoded data. Choose between original uploaded file or processed/archived version with OCR improvements.
AI agents call download_document to retrieve information from Paperless-NGX 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 returns document data in base64-encoded format without any side effects. It does not modify, delete, create, execute code, or process financial transactions. The user can only access documents that already exist in the Paperless-NGX system, making it a Read operation with minimal risk profile.
From the tool's definition Tool description states it "Download[s] a document file" and "Choose[s] between original uploaded file or processed/archived version". The action is retrieval only with no modification, deletion, or execution of code.
