This server has 7 well-named, action-verb tools with clear descriptions and reasonable schemas. However, several critical gaps prevent a higher score: (1) Output schemas are completely undocumented, callers have no way to know what fields to expect from any tool; (2) Error handling is minimal, no recovery guidance, no field validation error messages; (3) Some parameters lack descriptions or constraints; (4) No pagination documented for list_videos despite potentially large result sets; (5) Security concerns: no mention of API key handling, file path validation for download_video and generate_video_with_reference. The server is above-average compared to typical community servers (which score 40-50), but falls short of production grade (70+) due to missing output documentation and error guidance.

• Document output schemas for all tools. Example for generate_video: { type: 'object', properties: { video_id: { type: 'string', description: 'Unique identifier for the generated video' }, status: { type: 'string', enum: ['processing', 'completed', 'failed'], description: 'Current state of the video generation job' }, created_at: { type: 'string', format: 'date-time', description: 'ISO 8601 timestamp of creation' }, estimated_completion_time: { type: 'string', format: 'date-time' }, error_message: { type: 'string', description: 'Human-readable error if status is failed' } }, required: ['video_id', 'status'] }
• Add validation and actionable error messages. For seconds parameter: validate 4 <= value <= 20, return 'Invalid seconds: must be 4 - 20. You provided: {value}'. For file paths: validate does-not-escape-base-dir and is-readable-or-writable.
• Implement pagination for list_videos. Add cursor or offset/limit to input schema. Document return format: { videos: [...], total_count: number, next_cursor?: string }. Cap default limit to 10 - 20.
• Add recovery guidance to errors. Instead of generic 'API error', return 'Video generation failed: model may be overloaded. Retry in 30 seconds or try sora-2 model instead of sora-2-pro.'
• Add file size and format constraints to descriptions. generate_video_with_reference: 'reference_image must be PNG, JPG, WebP, max 20MB, aspect ratio 1:1 to 16:9.' download_video: 'output_path must be writable, will write 50 - 500MB depending on seconds and size.'
• Add field-level constraints to parameter descriptions. model enum already present, but add 'Do not pass unknown values; must be exactly one of: sora-2, sora-2-pro'. seconds: 'Integer between 4 and 20 inclusive; fractional seconds are not supported.'
