Server has 11 well-named tools with complete input schemas and descriptions. Naming follows verb_noun convention (get_, list_, add_, pause_, resume_, delete_, set_, toggle_). Descriptions are present and actionable (avg ~120 chars). However, output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal (generic HTTP errors, no recovery guidance). Parameters lack enums for constrained values (e.g., 'filter' accepts free-form strings instead of enum). No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels. Missing pagination support on list tools. Responses likely include raw API fields without stripping irrelevant metadata.

• Add output schema documentation to all tools. Example for qbittorrent_get_torrents: 'Returns: {torrents: [{hash, name, state, progress, dlspeed, upspeed, num_seeds, num_complete, num_leechs, num_incomplete, category, tags, size}], total_count: number}'.
• Convert free-form filter and sort parameters to enums. Define: filter: enum [all, downloading, seeding, completed, paused, active, inactive, stalled, stalled_uploading, stalled_downloading, error]; sort: enum [name, size, progress, dlspeed, upspeed, ratio, added_on].
• Add tool annotations to inputSchema. For destructive tools, add 'destructiveHint: true'. For read-only tools, add 'readOnlyHint: true'. Example: {name: 'qbittorrent_delete_torrents', inputSchema: {...}, destructiveHint: true}.
• Enhance error messages with recovery guidance. Replace 'API error 403' with 'Session expired or invalid credentials. Check QBITTORRENT_USERNAME and QBITTORRENT_PASSWORD environment variables.' For invalid hashes, return 'Torrent hash not found. Call qbittorrent_get_torrents to list valid hashes.'
• Add pagination to list tools. Add parameters: limit (1-100, default 20), offset (default 0). Return: {torrents: [...], total_count: number, has_more: boolean}.
