move_study · DICOM MCP Server MCP: Risk & Policy

WHAT IT DOES

What move_study does on DICOM MCP Server

AI agents use move_study to create or update resources in DICOM MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DICOM MCP Server environment.

WHY IT NEEDS A POLICY

Why move_study needs a policy

Moving studies in a DICOM system transfers medical imaging data between locations (e.g., PACS, VNA, or external endpoints). This is a Write operation because it modifies the data's location state reversibly. Severity is high because medical imaging data is sensitive (PHI/PII under HIPAA), and unauthorized movement could expose patient information, violate compliance, or disrupt clinical workflows.

From the tool's definition Tool name 'move_study' combined with sibling tool 'move_series' and server description stating the tool enables 'image transfer to AI endpoints'. The 'move_' prefix indicates data relocation/transfer rather than retrieval.

Verdict

move_study Rate-limited

move_study stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
