Get the current mouse cursor position in scaled coordinates.
AI agents call computer_cursor_position to retrieve information from Computer Use MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the current state of the mouse cursor without modifying any system state, data, or triggering external operations. It is purely informational and represents the least risky category of MCP tool operation.
From the tool's definition Tool name 'computer_cursor_position' and description state it 'Get[s] the current mouse cursor position' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get the current mouse cursor position in scaled coordinates. It is categorised as a Read tool in the Computer Use MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Computer Use MCP Server MCP server in PolicyLayer and add a rule for computer_cursor_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 Computer Use MCP Server. Nothing to install.
computer_cursor_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 computer_cursor_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 computer_cursor_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.
computer_cursor_position is provided by the Computer Use MCP Server MCP server (sebastianbaltes/claude_code_computer_use_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
