# mail_get_attachment Download an email attachment by message ID and attachment ID. Agent View of the PolicyLayer registry record for `mail_get_attachment`. HTML page: https://policylayer.com/tools/aiquila-nextcloud-mcp-server/mail-get-attachment ## Facts - Tool: `mail_get_attachment` - 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": "mail_get_attachment", "arguments": {} } } ``` ## Why mail_get_attachment is rated Low The tool retrieves (downloads) an email attachment—a read-only operation that accesses data without side effects. No data is created, modified, deleted, or overwritten. The action is passive and has no impact beyond returning the requested attachment content to the caller. From the tool's own definition: "Tool name 'mail_get_attachment' and description 'Download an email attachment by message ID and attachment ID' indicate retrieval of existing data without modification or deletion." ## Use case AI agents call mail_get_attachment 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": { "mail_get_attachment": {} } } ``` ## 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.
