# list_calendars List all calendars available to the current user, including their supported component types (events, tasks, journals) and metadata. Agent View of the PolicyLayer registry record for `list_calendars`. HTML page: https://policylayer.com/tools/aiquila-nextcloud-mcp-server/list-calendars ## Facts - Tool: `list_calendars` - 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_calendars", "arguments": {} } } ``` ## Why list_calendars is rated Low This tool retrieves and queries calendar data without creating, modifying, deleting, or executing any operations. It has no side effects and presents minimal security risk—calendars and their metadata are typically user-accessible information. Low severity reflects the limited blast radius if misused by an agent. From the tool's own definition: "Tool name is 'list_calendars' and description states it 'List all calendars available to the current user'. The verb 'list' and the action of retrieving calendar metadata with no modification capability clearly indicate a read-only operation." ## Use case AI agents call list_calendars 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_calendars": {} } } ``` ## 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.
