WHAT IT DOES

What submit_order does on Pharmacy MCP Server

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

WHY IT NEEDS A POLICY

Why submit_order needs a policy

This tool creates/modifies data (a new order in HIS) rather than merely reading or calculating. While the action is theoretically reversible (orders can be cancelled), submitting a medication order to a live hospital system has high severity due to potential for patient harm if incorrect medications/doses are ordered.

From the tool's definition Tool name is 'submit_order' and description states 'Submit a medication order to the HIS service.' This creates a new medication order record in the hospital information system, which is a reversible but significant modification to clinical data.
