WHAT IT DOES

What device_sim_generate_proxy does on Uefn

AI agents invoke device_sim_generate_proxy to trigger actions in Uefn. 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.

RISK

Why device_sim_generate_proxy is rated High

The tool generates and likely writes/executes a Python proxy class for a Verse device in a live editor. This goes beyond a simple read or write, as it involves running a code generation process that produces executable artifacts within the editor context. The blast radius is moderate since misuse could inject unexpected proxy code into the project.

From the tool's definition "Generate a Python simulation proxy class" — this triggers code generation (execution of a generation process) targeting a live UEFN editor environment

RECOMMENDED RULE

The rule that runs device_sim_generate_proxy safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Uefn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For device_sim_generate_proxy, this is the rule to start with:

device_sim_generate_proxy Rate-limited

device_sim_generate_proxy 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Uefn, apply this rule, and every device_sim_generate_proxy call is checked against it from then on.

FAQ

Questions about device_sim_generate_proxy

What does the device_sim_generate_proxy tool do? +

Generate a Python simulation proxy class for the selected Verse device. It is categorised as a Execute tool in the Uefn MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on device_sim_generate_proxy? +

Register the Uefn MCP server in PolicyLayer and add a rule for device_sim_generate_proxy: 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 Uefn. Nothing to install.

What risk level is device_sim_generate_proxy? +

device_sim_generate_proxy is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit device_sim_generate_proxy? +

Yes. Add a rate_limit block to the device_sim_generate_proxy 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.

How do I block device_sim_generate_proxy completely? +

Set action: deny in the PolicyLayer policy for device_sim_generate_proxy. 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.

What MCP server provides device_sim_generate_proxy? +

device_sim_generate_proxy is provided by the Uefn MCP server (quangdang46/uefn-verse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
