WHAT IT DOES

What update_dashboard does on Grafana MCP Server

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

RISK

Why update_dashboard is rated Medium

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_dashboard safely

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

update_dashboard Rate-limited

update_dashboard 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.
