HTML page: https://policylayer.com/tools/dwin-gharibi-arvancloud-mcp/arvan-git-diff ## Facts - Tool: `arvan_git_diff` - 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_git_diff", "arguments": {} } } ``` ## Why arvan_git_diff is rated Low This tool only retrieves and displays git diff information. It has no side effects, does not execute code, does not modify data, and does not delete anything. It is a read-only operation that queries the state of the git repository, making it a Read category tool with low severity. From the tool's own definition: "The tool 'arvan_git_diff' is described as showing 'the diff of unstaged (or, with ``staged``, staged) changes.' This is a query operation that displays version control differences without modifying, executing, or deleting any data." ## Use case AI agents call arvan_git_diff 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_git_diff": {} } } ``` ## 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.
