AI agents call list_user_preferences to retrieve information from Mcp Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user preference data without side effects. The verb 'list' is explicitly a Read operation—it queries and returns information without creating, modifying, deleting, or executing external operations. Even though the server provides broad system control, this specific tool is limited to data retrieval, making it the lowest-risk category.
From the tool's definition Tool name 'list_user_preferences' and description 'List all user preferences' indicate a query/retrieval operation with no modification or destructive capability.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for list_user_preferences:
{
"version": "1",
"default": "deny",
"tools": {
"list_user_preferences": {}
}
}list_user_preferences is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all user preferences. It is categorised as a Read tool in the Mcp Windows MCP Server, which means it retrieves data without modifying state.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for list_user_preferences: 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 Mcp Windows. Nothing to install.
list_user_preferences 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 list_user_preferences 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 list_user_preferences. 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.
list_user_preferences is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
