WHAT IT DOES

What dismiss_notification does on GitHub

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

RISK

Why dismiss_notification is rated Medium

Dismissing a notification modifies notification state in GitHub. While it could be argued this is somewhat destructive, notifications can typically be restored or re-triggered, making it a Write operation. Misuse could cause an AI agent to silently dismiss important notifications (security alerts, PR reviews), giving it medium severity.

From the tool's definition dismiss_notification - the tool dismisses (marks as read/done) a notification, which is a reversible state change

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs dismiss_notification safely

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

dismiss_notification Rate-limited

dismiss_notification 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.
