AI agents invoke connect_ur 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 initiates a live connection to a physical industrial robot arm over the network. While it is not destructive or financial, it triggers an external operation (connecting to a cobot) that enables subsequent motion commands and robot control. Misuse could allow unauthorized access to industrial robots, making this high severity.
From the tool's definition '连接UR' (Connect to UR) based on user-provided IP address — establishes a network connection to a physical Universal Robots cobot
Documented attack patterns abuse exactly the kind of access connect_ur 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 connect_ur:
{
"version": "1",
"default": "deny",
"tools": {
"connect_ur": {
"limits": [
{
"counter": "connect_ur_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}connect_ur 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.

根据用户提供的IP连接UR. 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 connect_ur: 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.
connect_ur 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 connect_ur 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 connect_ur. 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.
connect_ur 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.
