Get all actors in the current level.
AI agents call get_all_actors 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 a list of actors from the level without modifying, deleting, or executing any operations. It is purely informational and carries minimal risk if misused by an agent—the worst outcome would be unnecessary API calls or information disclosure about level contents.
From the tool's definition Tool name 'get_all_actors' and description 'Get all actors in the current level' indicate a retrieval/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_all_actors 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 get_all_actors:
{
"version": "1",
"default": "deny",
"tools": {
"get_all_actors": {}
}
}get_all_actors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all actors in the current level. 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 get_all_actors: 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.
get_all_actors 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 get_all_actors 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 get_all_actors. 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.
get_all_actors 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.
