AI agents call get_robot_mode 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 and retrieves the current mode/state of a Universal Robot. It has no side effects, does not execute commands, does not modify data, and does not trigger any physical robot actions. It is purely informational, making it a Read category tool with low severity since misuse would only expose operational status information without enabling harmful physical actions.
From the tool's definition Tool name 'get_robot_mode' and description '获取指定IP机器人的运行状态' (Get the running state of the robot with specified IP) indicate a read-only operation that retrieves the operational status of a robot without modifying any state or triggering any actions.
Documented attack patterns abuse exactly the kind of access get_robot_mode 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_robot_mode:
{
"version": "1",
"default": "deny",
"tools": {
"get_robot_mode": {}
}
}get_robot_mode is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取指定IP机器人的运行状态. 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_robot_mode: 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_robot_mode 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_robot_mode 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_robot_mode. 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_robot_mode 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.
