WHAT IT DOES

What check_ad_policy does on Hermoso

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

RISK

RECOMMENDED RULE

The rule that runs check_ad_policy safely

check_ad_policy Allowed

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

  "tools": {
    "check_ad_policy": {}
  }
}

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

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