level

// WHEN AI AGENTS USE THIS TOOL

AI agents may call level to permanently remove or destroy resources in Ue. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON LEVEL

Without a policy, an AI agent could call level in a loop, permanently destroying resources in Ue. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

ue.yaml

tools:
  level:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"

Block by default and require explicit approval.

How do I enforce a policy on level? +

Add a rule in your Intercept YAML policy under the tools section for level. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ue MCP server.

What risk level is level? +

level is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit level? +

Yes. Add a rate_limit block to the level rule in your Intercept 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 level completely? +

Set action: deny in the Intercept policy for level. 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 level? +

level is provided by the Ue MCP server (ue-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
