Export a JSON report of all Verse device properties to the Saved folder.
AI agents use device_export_report to create or update resources in Uefn — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Uefn environment.
This tool creates a new file (JSON report) in the file system, which is a reversible write operation. It does not execute arbitrary code, delete data, or trigger financial operations.
From the tool's definition Tool description states it "Export[s] a JSON report" to "the Saved folder", indicating creation/writing of a new file with exported data.
Documented attack patterns abuse exactly the kind of access device_export_report gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Uefn, and nothing reaches the server without passing your rules. This is the rule we recommend for device_export_report:
{
"version": "1",
"default": "deny",
"tools": {
"device_export_report": {
"limits": [
{
"counter": "device_export_report_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}device_export_report stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Export a JSON report of all Verse device properties to the Saved folder. It is categorised as a Write tool in the Uefn MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Uefn MCP server in PolicyLayer and add a rule for device_export_report: 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.
device_export_report is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the device_export_report 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 device_export_report. 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.
device_export_report 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.
Start from Uefn, 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.
