WHAT IT DOES

What get_image does on NapCat MCP Server

AI agents call get_image to retrieve information from NapCat MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_image is rated Low

The tool retrieves or queries image data without altering, deleting, or executing operations. It fits the Read category as it only fetches information. Severity is low because image metadata retrieval poses minimal risk even if misused by an agent. Confidence is high given the clear retrieval semantics in both name and description.

From the tool's definition Tool name is 'get_image' and description states 'Get image information' - this is a retrieval operation with no modification or side effects.
