WHAT IT DOES

What recent_events does on Nogra

AI agents call recent_events to retrieve information from Nogra without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why recent_events is rated Low

The name indicates a query or retrieval operation typical of Read category tools. Without a description, confidence is lowered, but the semantics of 'recent_events' strongly imply passive data retrieval rather than modification, execution, or destructive action. In the context of a 'verify-before-done trust layer', this likely serves to display or query past actions for audit/review purposes.

From the tool's definition Tool name 'recent_events' suggests retrieval of historical data with no modification. Description is empty, limiting confidence.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs recent_events safely

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

recent_events Allowed

recent_events is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "recent_events": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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