Check whether a set of dimensions and metrics can be used together in a GA4 report. Useful before running a complex report to avoid INCOMPATIBLE errors.
AI agents call ga_check_compatibility to retrieve information from Apple Shortcuts without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query or validation check against GA4 to determine metric/dimension compatibility. It retrieves information (compatibility status) but has no side effects—it does not create, modify, execute code, delete, or commit financial obligations. The blast radius of misuse is minimal; an agent could only waste API quota or receive error information.
From the tool's definition The tool description states it 'Check[s] whether a set of dimensions and metrics can be used together in a GA4 report' — a read-only validation operation that queries the Google Analytics API to verify compatibility without modifying, executing, or deleting…
Documented attack patterns abuse exactly the kind of access ga_check_compatibility gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Shortcuts, and nothing reaches the server without passing your rules. This is the rule we recommend for ga_check_compatibility:
{
"version": "1",
"default": "deny",
"tools": {
"ga_check_compatibility": {}
}
}ga_check_compatibility is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check whether a set of dimensions and metrics can be used together in a GA4 report. Useful before running a complex report to avoid INCOMPATIBLE errors. It is categorised as a Read tool in the Apple Shortcuts MCP Server, which means it retrieves data without modifying state.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for ga_check_compatibility: 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 Apple Shortcuts. Nothing to install.
ga_check_compatibility 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 ga_check_compatibility 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 ga_check_compatibility. 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.
ga_check_compatibility is provided by the Apple Shortcuts MCP server (@mindstone/mcp-server-apple-shortcuts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Shortcuts, 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.
