Download a user image file as base64-safe data.
AI agents call get_user_image_media to retrieve information from Mealie MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns user image data in base64 format. This is a read-only operation with no side effects, modification of data, or destruction. The worst-case misuse would be unauthorized access to images the user can already see, not data loss or financial impact. Severity is low due to limited blast radius assuming standard access controls.
From the tool's definition Tool name 'get_user_image_media' and description 'Download a user image file as base64-safe data' indicate retrieval of existing image data without modification.
