# arvan_list_regions List all ArvanCloud IaaS regions (datacenters) and their codes. Agent View of the PolicyLayer registry record for `arvan_list_regions`. HTML page: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-list-regions ## Facts - Tool: `arvan_list_regions` - 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: 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": "arvan_list_regions", "arguments": {} } } ``` ## Why arvan_list_regions is rated Low This tool retrieves metadata about available cloud regions and their identifiers. It performs a read-only query with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal—an AI agent obtaining this information cannot cause damage or unauthorized state changes. It is informational only. From the tool's own definition: "Tool name 'arvan_list_regions' and description 'List all ArvanCloud IaaS regions (datacenters) and their codes' indicate a query/retrieval operation with no side effects." ## Use case AI agents call arvan_list_regions to retrieve information from ArvanCloud 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 ArvanCloud MCP Server: ```json { "version": "1", "default": "deny", "tools": { "arvan_list_regions": {} } } ``` ## 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.
