Get regional settings from a SharePoint site
AI agents call getRegionalSettings to retrieve information from SharePoint Online MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though getRegionalSettings only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access getRegionalSettings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SharePoint Online MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getRegionalSettings:
{
"version": "1",
"default": "deny",
"tools": {
"getRegionalSettings": {}
}
}getRegionalSettings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
