create_incident · Mcp Grafana MCP: Risk & Policy

WHAT IT DOES

What create_incident does on Mcp Grafana

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

WHY IT NEEDS A POLICY

Why create_incident needs a policy

This tool creates a new incident record in Grafana, which is a reversible write operation. While incident creation has operational consequences (alerting on-call users, triggering incident workflows), the action itself creates data that can be modified or closed. It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition Tool name 'create_incident' and description 'Create a new Grafana incident' indicate data creation that modifies the incident management system state.
