# arvan_s3_list_objects List objects in a bucket (optionally under a prefix). Agent View of the PolicyLayer registry record for `arvan_s3_list_objects`. HTML page: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-s3-list-objects ## Facts - Tool: `arvan_s3_list_objects` - 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_s3_list_objects", "arguments": {} } } ``` ## Why arvan_s3_list_objects is rated Low This tool performs a simple enumeration of objects in cloud storage, analogous to listing directory contents. It has no side effects, does not modify data, does not execute code or commands, and does not trigger external operations. The blast radius of misuse is limited to potential information disclosure of object names within the bucket, which is low-severity. From the tool's own definition: "Tool name 'arvan_s3_list_objects' and description 'List objects in a bucket (optionally under a prefix)' indicate a read-only query operation that retrieves/enumerates data without modification, deletion, or execution." ## Use case AI agents call arvan_s3_list_objects 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_s3_list_objects": {} } } ``` ## 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.
