AI agents invoke send_program_script 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 arbitrary programs/scripts directly to a physical industrial robot (Universal Robots cobot). Executing arbitrary URScript on a robot arm can cause physical movement, collisions, equipment damage, or injury to nearby personnel. This is an Execute action with critical severity due to real-world physical consequences of misuse.

Documented attack patterns abuse exactly the kind of access send_program_script 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 send_program_script:
{
"version": "1",
"default": "deny",
"tools": {
"send_program_script": {
"limits": [
{
"counter": "send_program_script_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}send_program_script 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.

发送脚本到指定IP的机器人。. 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 send_program_script: 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.
send_program_script 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 send_program_script 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 send_program_script. 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.
send_program_script 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.
