# restore_file_version Restore a previous version of a file (creates a new current version from the old one) Agent View of the PolicyLayer registry record for `restore_file_version`. HTML page: https://policylayer.com/tools/aiquila-nextcloud-mcp-server/restore-file-version ## Facts - Tool: `restore_file_version` - 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: 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": "restore_file_version", "arguments": {} } } ``` ## Why restore_file_version is rated Medium The tool creates a new current version from a previous version, which is a write operation that modifies the file system state. It is reversible (the current version can be restored to again), so it does not qualify as Destructive. From the tool's own definition: "Tool description states it 'Restore a previous version of a file (creates a new current version from the old one)', which involves modifying file state by creating a new version. This is a reversible modification operation." ## Use case AI agents use restore_file_version to create or update resources in AIquila — Nextcloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AIquila — Nextcloud MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. 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": { "restore_file_version": { "limits": [ { "counter": "restore_file_version_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## 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.
