[WRITE] Fetch all provisioned alert rules via the read-only provisioning API.
AI agents call list_provisioned_alert_rules to retrieve information from Mcp Read Only Grafana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the '[WRITE]' tag in the description, the actual operation is a fetch/query against a read-only API endpoint. The tool retrieves existing alert rules without creating, modifying, or deleting data. The '[WRITE]' tag appears to be a labeling error or server-wide designation that does not reflect this tool's actual functionality. List operations are inherently Read category with minimal risk.
From the tool's definition Tool name 'list_provisioned_alert_rules' and description 'Fetch all provisioned alert rules via the read-only provisioning API' indicate a retrieval operation with no side effects.

Register the Mcp Read Only Grafana MCP server in PolicyLayer and add a rule for list_provisioned_alert_rules: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Read Only Grafana. Nothing to install.
list_provisioned_alert_rules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_provisioned_alert_rules rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_provisioned_alert_rules. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_provisioned_alert_rules is provided by the Mcp Read Only Grafana MCP server (lukleh/mcp-read-only-grafana). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
