AI agents invoke movel_y 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 sends real-time physical motion commands to a Universal Robots cobot, causing its arm to move in physical space. This is an Execute-category action (triggering external physical operations). Misuse could cause physical harm to people, equipment, or the robot itself, warranting high severity.
From the tool's definition 命令指定IP机器人的TCP沿Y轴方向移动 — 'commands the TCP of the robot at a specified IP to move along the Y-axis direction'
Documented attack patterns abuse exactly the kind of access movel_y 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_y:
{
"version": "1",
"default": "deny",
"tools": {
"movel_y": {
"limits": [
{
"counter": "movel_y_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}movel_y 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_y: 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_y 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_y 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_y. 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_y 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.
