# arvan_kubectl Run an arbitrary kubectl command (e.g. ["get","pods","-o","wide"]). Agent View of the PolicyLayer registry record for `arvan_kubectl`. HTML page: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-kubectl ## Facts - Tool: `arvan_kubectl` - Server: ArvanCloud MCP Server (`dwin-gharibi/arvancloud-mcp`) — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp.md - Homepage: https://github.com/dwin-gharibi/arvancloud-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "arvan_kubectl", "arguments": {} } } ``` ## Why arvan_kubectl is rated High kubectl commands can execute arbitrary operations against Kubernetes clusters, including reading secrets, deploying malicious workloads, modifying cluster configuration, accessing sensitive data, and triggering cascading infrastructure changes. An AI agent with access to arbitrary kubectl execution could compromise the entire cluster and hosted applications. From the tool's own definition: "Tool description explicitly states 'Run an arbitrary kubectl command' with example passing arguments to kubectl. The word 'arbitrary' and the ability to pass command arguments indicates unrestricted execution capability." ## Use case AI agents invoke arvan_kubectl to trigger actions in ArvanCloud MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches ArvanCloud MCP Server: ```json { "version": "1", "default": "deny", "tools": { "arvan_kubectl": { "limits": [ { "counter": "arvan_kubectl_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on ArvanCloud MCP Server (231) - `arvan_delete_cdn_app` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-cdn-app.md - `arvan_delete_dns_record` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-dns-record.md - `arvan_delete_domain` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-domain.md - `arvan_delete_firewall_rule` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-firewall-rule.md - `arvan_delete_floating_ip` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-floating-ip.md - `arvan_delete_log_forwarder` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-log-forwarder.md - `arvan_delete_page_rule` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-page-rule.md - `arvan_delete_ptr_record` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-ptr-record.md - `arvan_delete_rate_limit_rule` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-rate-limit-rule.md - `arvan_delete_security_group` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-security-group.md - `arvan_delete_security_rule` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-security-rule.md - `arvan_delete_server` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-server.md - `arvan_delete_ssh_key` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-ssh-key.md - `arvan_delete_subnet` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-subnet.md - `arvan_delete_tag` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-tag.md - `arvan_delete_volume` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-delete-volume.md - `arvan_helm_uninstall` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-helm-uninstall.md - `arvan_iac_terraform_destroy` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-iac-terraform-destroy.md - `arvan_k8s_delete` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-k8s-delete.md - `arvan_live_delete_channel` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-live-delete-channel.md - `arvan_purge_cache` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-purge-cache.md - `arvan_rebuild_server` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-rebuild-server.md - `arvan_s3_delete_bucket` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-s3-delete-bucket.md - `arvan_s3_delete_object` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-s3-delete-object.md - `arvan_s3_delete_objects` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-s3-delete-objects.md - `arvan_task_cancel` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-task-cancel.md - `arvan_vod_delete_audio` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-vod-delete-audio.md - `arvan_vod_delete_channel` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-vod-delete-channel.md - `arvan_vod_delete_file` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-vod-delete-file.md - `arvan_vod_delete_profile` — Destructive — https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-vod-delete-profile.md - …and 201 more: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp.md ## For agents This record is a snapshot.
