## Why openehr_ehr_get is rated Low

Despite the empty description, the naming convention strongly indicates this fetches an EHR record by identifier. No deletion, creation, execution of arbitrary code, or financial operations occur. The blast radius is minimal—unauthorized EHR access could expose protected health information, but that is a confidentiality/authentication concern rather than a tool misuse risk.

From the tool's own definition: "Tool name 'openehr_ehr_get' indicates a retrieval operation. In the context of the openEHR server's other tools (e.g., openehr_ehr_list, openehr_composition_get), 'get' is consistently used for data retrieval without modification."

## Use case

AI agents call openehr_ehr_get 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches openEHR MCP Server:

```json
