Return the current mouse cursor (x,y).
AI agents call cursor_position to retrieve information from Hermes Computer Use without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns the current cursor coordinates. It does not move the cursor, click, modify any state, or trigger any external operation. It is a pure read operation with minimal blast radius.
From the tool's definition 'Return the current mouse cursor (x,y)' — purely retrieves positional data with no side effects
Attacks that exploit this kind of access
Return the current mouse cursor (x,y). It is categorised as a Read tool in the Hermes Computer Use MCP Server, which means it retrieves data without modifying state.
Register the Hermes Computer Use MCP server in PolicyLayer and add a rule for 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 Hermes Computer Use. Nothing to install.
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 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 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.
cursor_position is provided by the Hermes Computer Use MCP server (noah3521/hermes-computer-use). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
