WHY IT NEEDS A POLICY

Why create_contact_point needs a policy

Contact points in Grafana define notification destinations (email, Slack, PagerDuty, etc.) for alerts. Creating a contact point modifies Grafana's configuration reversibly and could redirect critical alerts to attacker-controlled endpoints, enabling alert suppression or social engineering. This is a Write operation (creates data) rather than Read (no query), Execute (no arbitrary code), or Destructive (reversible).

From the tool's definition Tool named 'create_contact_point' on a Grafana MCP server with known write-capable sibling tools (create_alert_rule, create_folder, create_mute_timing). The 'create_' prefix indicates data creation/modification. Tool description is empty, limiting precision.
