AI agents call get_mouse_position 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 is a pure read operation that queries the current mouse cursor coordinates. It does not modify any system state, execute commands, delete data, or commit financial transactions. The blast radius of misuse is minimal — an attacker could only learn cursor position, which has no security or operational impact.
From the tool's definition Tool name is 'get_mouse_position' and description states 'Get current mouse cursor position' — this retrieves current state without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_mouse_position gives an agent:
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 get_mouse_position:
{
"version": "1",
"default": "deny",
"tools": {
"get_mouse_position": {}
}
}get_mouse_position is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get current mouse cursor position. 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 get_mouse_position: 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.
get_mouse_position 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 get_mouse_position 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 get_mouse_position. 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.
get_mouse_position 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.
