## Why openehr_compositions_list is rated Low

This tool retrieves or enumerates existing compositions from an openEHR EHR system. List operations are read-only with no mutation of data. Severity is medium rather than low because health records (EHR data) are sensitive personal health information; unauthorized listing could expose PHI, though the tool itself performs no destructive or financial action.

From the tool's own definition: "Tool name 'openehr_compositions_list' indicates a list/query operation that retrieves compositions from an openEHR system."

## Use case

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