Export full world state (all actors with properties) as JSON for AI analysis.
AI agents call world_state_export to retrieve information from Uefn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and exports data (world state) without modifying it. It reads all actors and their properties and serializes them to JSON. The medium severity reflects that it exports potentially large amounts of world data which could expose sensitive project details, but it has no write or destructive side effects.

Documented attack patterns abuse exactly the kind of access world_state_export 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 world_state_export:
{
"version": "1",
"default": "deny",
"tools": {
"world_state_export": {}
}
}world_state_export is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Export full world state (all actors with properties) as JSON for AI analysis. It is categorised as a Read tool in the Uefn MCP Server, which means it retrieves data without modifying state.
Register the Uefn MCP server in PolicyLayer and add a rule for world_state_export: 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.
world_state_export is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the world_state_export 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 world_state_export. 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.
world_state_export 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.
