WHAT IT DOES

What dismiss_alert does on Nodebench

AI agents use dismiss_alert to create or update resources in Nodebench, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nodebench environment.

RISK

The tool modifies the state of an alert (marking it as dismissed/seen), which is a reversible write operation. It doesn't delete data permanently but changes alert visibility/status. Misuse could cause important alerts to be silently suppressed, hence medium severity.

RECOMMENDED RULE

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

dismiss_alert Rate-limited

dismiss_alert stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
