Server has 6 tools with basic schemas and descriptions, but significant gaps in parameter documentation and error handling. Tool names follow verb_noun convention (multiview_*), but descriptions are minimal (10-50 chars, well below the 194-char baseline). Most parameters lack descriptions entirely. No output schemas documented. Error handling is absent, tools return raw API responses or generic errors without recovery guidance. This is a typical community STDIO server with incomplete definitions.

• Expand tool descriptions to 100-200 chars. Include WHAT the tool does, WHEN to call it, and WHAT it returns. E.g. 'multiview_streams_list: Returns a list of all active streams in the grid with their IDs, names, URLs, and playback status. Call this first to discover available streams before adding or deleting.'
• Add descriptions to all parameters. For 'stream_url', specify: 'Stream URL (supports YouTube, Twitch, HLS, DASH, RTSP, local file paths). Must be a valid, accessible URL or file path.' For 'output_path', specify: 'Absolute file path to save PNG screenshot. If omitted, defaults to a temp file in /tmp or %TEMP%.'
• Document output schemas for each tool. E.g. multiview_streams_list returns {streams: [{id: string, name: string, url: string, logo_url?: string, is_muted: boolean, status: 'playing'|'paused'|'error'}, ...], total: number}.
• Implement structured error responses. Replace generic exceptions with: {error: 'API_UNREACHABLE', message: 'MultiviewGrid API at http://localhost:3737 is not responding. Ensure the server is running and accessible.', retryable: true, recovery: 'Check that MultiviewGrid is running with --api-port 3737.'}
• Add confirmation step to multiview_stream_delete. Require a 'confirm' boolean parameter (default false) or return a confirmation token that must be passed in a second call. Prevents accidental deletion.
