Server has 4 tools with basic descriptions and parameter schemas, but significant gaps prevent production use. Tool names follow verb_noun convention (view_*, request_*, respond_*), which is good. However, parameter descriptions are minimal (1-2 sentences), output schemas are undocumented, and error handling provides no recovery guidance. The 'selected_time' parameter in respond_to_meeting_request lacks type definition (marked as 'object' with no schema). No tool declares what it returns or how to chain results. Descriptions average ~60 chars, below the 194-char baseline for A+ tools. No parameter validation rules, constraints, or examples of valid input formats are documented.

• Document output schema for each tool. Example: 'Returns: {schedules: [{id: int, title: str, start_time: ISO8601, end_time: ISO8601, attendees: [str]}], total: int}'
• Replace 'object' type for selected_time with explicit schema: {type: 'object', properties: {start_time: {type: 'string', format: 'date-time'}, end_time: {type: 'string', format: 'date-time'}}, required: ['start_time', 'end_time']}
• Add format constraints to parameters: date should specify 'ISO 8601 format (YYYY-MM-DD)' or 'natural language (e.g., today, tomorrow, next Monday)'
• Enhance error messages with recovery guidance: catch HTTPError and return '{error: 'Failed to fetch schedules', suggestion: 'Check API key is set and server is reachable at ' + SERVER_URL}'
• Add pagination to view_meeting_schedules and view_meeting_requests: accept limit (1-100, default 20) and offset parameters; return {items: [...], total: int, has_more: bool}
