AI agents invoke movel_z to trigger actions in Nonead Universal-Robots MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool issues real-time physical motion commands to a Universal Robots cobot, moving its tool center point in physical space. Misuse by an AI agent could cause physical harm to people, damage equipment, or destroy workpieces. Physical robot motion commands are Execute-category with critical severity due to the potential for irreversible physical harm and safety incidents.
From the tool's definition 命令指定IP机器人的TCP沿Y轴方向移动 — commands a physical robot's TCP (Tool Center Point) to move along an axis; part of a server enabling 'real-time motion commands' for Universal Robots cobots
Documented attack patterns abuse exactly the kind of access movel_z 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 movel_z:
{
"version": "1",
"default": "deny",
"tools": {
"movel_z": {
"limits": [
{
"counter": "movel_z_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}movel_z stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
命令指定IP机器人的TCP沿Y轴方向移动. It is categorised as a Execute tool in the Nonead Universal-Robots MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nonead Universal-Robots MCP Server MCP server in PolicyLayer and add a rule for movel_z: 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.
movel_z is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the movel_z 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 movel_z. 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.
movel_z 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.
