list_dicom_nodes
AI agents call list_dicom_nodes to retrieve information from DICOM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests retrieval of available DICOM nodes without modification. In the context of a DICOM server management tool, listing nodes is a discovery/enumeration operation typical of Read category. However, the empty description prevents higher confidence.
