# arvan_s3_put_object A write tool on the ArvanCloud MCP Server MCP server. Agent View of the PolicyLayer registry record for `arvan_s3_put_object`. HTML page: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-s3-put-object ## Facts - Tool: `arvan_s3_put_object` - 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: Write (Medium 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_s3_put_object", "arguments": {} } } ``` ## Why arvan_s3_put_object is rated Medium The 's3_put_object' operation creates or modifies data in cloud object storage, which is reversible (objects can be deleted or overwritten later). This is a Write action rather than Read (no query), Execute (no arbitrary code execution—just object upload), or Destructive (upload is not irreversible). From the tool's own definition: "Tool name 'arvan_s3_put_object' indicates S3 object creation/upload. The 's3_put_object' operation is a standard AWS S3 API call that creates or overwrites objects in cloud storage." ## Use case AI agents use arvan_s3_put_object to create or update resources in ArvanCloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ArvanCloud MCP Server environment. ## 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_s3_put_object": { "limits": [ { "counter": "arvan_s3_put_object_rate", "window": "minute", "max": 30, "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.
