Inspect one day by combining the daily snapshot with the raw manifest, and explain metric/raw gaps.
AI agents call health.inspect_day to retrieve information from Nucleus Apple without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes health data for a single day by combining and examining existing snapshots and manifests. It performs no creation, modification, deletion, or external code execution. The inspection and explanation of metric gaps are analytic operations on data that already exists, consistent with the Read category.
From the tool's definition Tool description uses 'inspect' and 'read' operations (combine snapshots, examine metrics) with no modification verbs.
Documented attack patterns abuse exactly the kind of access health.inspect_day gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nucleus Apple, and nothing reaches the server without passing your rules. This is the rule we recommend for health.inspect_day:
{
"version": "1",
"default": "deny",
"tools": {
"health.inspect_day": {}
}
}health.inspect_day is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Inspect one day by combining the daily snapshot with the raw manifest, and explain metric/raw gaps. It is categorised as a Read tool in the Nucleus Apple MCP Server, which means it retrieves data without modifying state.
Register the Nucleus Apple MCP server in PolicyLayer and add a rule for health.inspect_day: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nucleus Apple. Nothing to install.
health.inspect_day is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the health.inspect_day rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for health.inspect_day. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
health.inspect_day is provided by the Nucleus Apple MCP server (zish-rob-crur/nucleus-apple-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nucleus Apple, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
