AI agents call get_actual_robot_voltage to retrieve information from Nonead Universal-Robots 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 voltage state of a Universal Robots cobot. It retrieves real-time telemetry data but does not execute commands, modify settings, or trigger physical actions. Reading voltage is a non-destructive diagnostic operation with minimal risk if misused by an AI agent.
From the tool's definition Tool name 'get_actual_robot_voltage' and description '获取指定IP机器人的电压（伏特）' (Get the voltage of the robot at the specified IP in volts) indicate retrieval of sensor/operational data without modification.
Documented attack patterns abuse exactly the kind of access get_actual_robot_voltage gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nonead Universal-Robots MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_actual_robot_voltage:
{
"version": "1",
"default": "deny",
"tools": {
"get_actual_robot_voltage": {}
}
}get_actual_robot_voltage is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
获取指定IP机器人的电压（伏特）. It is categorised as a Read tool in the Nonead Universal-Robots MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nonead Universal-Robots MCP Server MCP server in PolicyLayer and add a rule for get_actual_robot_voltage: 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 Nonead Universal-Robots MCP Server. Nothing to install.
get_actual_robot_voltage 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_actual_robot_voltage 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_actual_robot_voltage. 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_actual_robot_voltage is provided by the Nonead Universal-Robots MCP Server MCP server (nonead/nonead-universal-robots-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nonead Universal-Robots MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
