What health_summary does on AirMCP
AI agents call health_summary to retrieve information from AirMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why health_summary is rated Low
This tool queries and retrieves existing health information from the user's Apple Health ecosystem to display a summary dashboard. It performs no writes, deletions, executions, or financial transactions. The read-only nature of retrieving a health summary dashboard presents minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'health_summary' and description 'Get a combined health dashboard: today' indicates retrieval of health data with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs health_summary safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For health_summary, this is the rule to start with:
health_summary is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every health_summary call is checked against it from then on.
