# list_service_metric_definitions List metric definitions for a specific monitoring service type Agent View of the PolicyLayer registry record for `list_service_metric_definitions`. HTML page: https://policylayer.com/tools/takashito-linode-mcp-server/list-service-metric-definitions ## Facts - Tool: `list_service_metric_definitions` - Server: Linode MCP Server (`takashito/linode-mcp-server`) — https://policylayer.com/tools/takashito-linode-mcp-server.md - Homepage: https://github.com/takashito/linode-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "list_service_metric_definitions", "arguments": {} } } ``` ## Why list_service_metric_definitions is rated Low This tool retrieves and lists metric definitions—informational data about available monitoring metrics. It performs no state changes, does not execute operations, and does not access sensitive operational data beyond schema/metadata. The 'list' verb and 'definitions' object confirm this is a read-only query operation with minimal blast radius if misused by an AI agent. From the tool's own definition: "Tool name 'list_service_metric_definitions' and description 'List metric definitions for a specific monitoring service type' indicate a retrieval operation that queries monitoring metadata without modifying or executing actions." ## Use case AI agents call list_service_metric_definitions to retrieve information from Linode MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Linode MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_service_metric_definitions": {} } } ``` ## Other tools on Linode MCP Server (415) - `cancel_account` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/cancel-account.md - `cancel_backups` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/cancel-backups.md - `cancel_object_storage` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/cancel-object-storage.md - `delete_alert_definition` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-alert-definition.md - `delete_api_token` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-api-token.md - `delete_config_interface` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-config-interface.md - `delete_domain` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-domain.md - `delete_domain_record` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-domain-record.md - `delete_firewall` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-firewall.md - `delete_firewall_device` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-firewall-device.md - `delete_image` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-image.md - `delete_image_sharegroup` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-image-sharegroup.md - `delete_instance` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-instance.md - `delete_instance_config` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-instance-config.md - `delete_instance_disk` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-instance-disk.md - `delete_ipv4_address` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-ipv4-address.md - `delete_ipv6_range` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-ipv6-range.md - `delete_kubernetes_cluster` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-cluster.md - `delete_kubernetes_control_plane_acl` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-control-plane-acl.md - `delete_kubernetes_kubeconfig` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-kubeconfig.md - `delete_kubernetes_node` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-node.md - `delete_kubernetes_node_pool` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-node-pool.md - `delete_kubernetes_service_token` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-kubernetes-service-token.md - `delete_linode_interface` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-linode-interface.md - `delete_log_destination` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-log-destination.md - `delete_log_stream` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-log-stream.md - `delete_longview_client` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-longview-client.md - `delete_mysql_instance` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-mysql-instance.md - `delete_nodebalancer` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-nodebalancer.md - `delete_notification_channel` — Destructive — https://policylayer.com/tools/takashito-linode-mcp-server/delete-notification-channel.md - …and 385 more: https://policylayer.com/tools/takashito-linode-mcp-server.md ## For agents This record is a snapshot.
