# list_system_tags List all available system tags in Nextcloud with their IDs, names, and properties. Use this to find tag IDs before assigning them to files. Agent View of the PolicyLayer registry record for `list_system_tags`. HTML page: https://policylayer.com/tools/aiquila-nextcloud-mcp-server/list-system-tags ## Facts - Tool: `list_system_tags` - Server: AIquila — Nextcloud MCP Server (`elgorro/aiquila`) — https://policylayer.com/tools/aiquila-nextcloud-mcp-server.md - Homepage: https://github.com/elgorro/aiquila.git - 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": "list_system_tags", "arguments": {} } } ``` ## Why list_system_tags is rated Low This tool performs a read-only operation to enumerate and display existing system tags and their metadata. There are no side effects, data modification, deletion, or external state changes. It is purely informational, used to help an agent discover available tags before taking other actions. The blast radius of misuse is minimal—an agent could only access tag information already present in the system. From the tool's own definition: "Tool description states 'List all available system tags' — a query operation that retrieves data without modification. The phrase 'find tag IDs' confirms it is a lookup/discovery function." ## Use case AI agents call list_system_tags to retrieve information from AIquila — Nextcloud 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 AIquila — Nextcloud MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_system_tags": {} } } ``` ## Other tools on AIquila — Nextcloud MCP Server (294) - `bulk_file_operations` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/bulk-file-operations.md - `circles_delete` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/circles-delete.md - `circles_remove_member` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/circles-remove-member.md - `clear_out_of_office` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/clear-out-of-office.md - `clear_user_status_message` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/clear-user-status-message.md - `delete` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete.md - `delete_all_form_submissions` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-all-form-submissions.md - `delete_all_notifications` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-all-notifications.md - `delete_announcement` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-announcement.md - `delete_bookmark` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-bookmark.md - `delete_bookmark_folder` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-bookmark-folder.md - `delete_bookmark_tag` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-bookmark-tag.md - `delete_contact` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-contact.md - `delete_coworker` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-coworker.md - `delete_event` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-event.md - `delete_feed` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-feed.md - `delete_form` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-form.md - `delete_form_option` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-form-option.md - `delete_form_question` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-form-question.md - `delete_form_share` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-form-share.md - `delete_form_submission` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-form-submission.md - `delete_map` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-map.md - `delete_map_device` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-map-device.md - `delete_map_favorite` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-map-favorite.md - `delete_news_folder` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-news-folder.md - `delete_note` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-note.md - `delete_poll` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-poll.md - `delete_poll_comment` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-poll-comment.md - `delete_poll_option` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-poll-option.md - `delete_poll_share` — Destructive — https://policylayer.com/tools/aiquila-nextcloud-mcp-server/delete-poll-share.md - …and 264 more: https://policylayer.com/tools/aiquila-nextcloud-mcp-server.md ## For agents This record is a snapshot.
