WHAT IT DOES

What webhooks_list does on Munin

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

RISK

Why webhooks_list is rated Low

This tool retrieves and displays webhook subscription information without creating, modifying, deleting, or executing anything. It is a passive query operation. The low severity reflects that webhook configuration metadata is informational and non-sensitive (secrets are explicitly not exposed).

From the tool's definition Tool name 'webhooks_list' and description 'List all webhook subscriptions for your org' indicates retrieval of existing data with no side effects. The note about secrets not being returned further confirms this is a read-only operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs webhooks_list safely

webhooks_list Allowed

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

    "webhooks_list": {}
  }
}

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

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