Server demonstrates solid tool naming, descriptions, and schema definitions across 12 tools. All tools use clear verb_noun naming (get_*) and have substantial descriptions (100-250 chars). Input schemas are comprehensive with Zod validation and typed parameters. Most parameters include descriptions and constraints via enums or regex validation. The server follows good composition patterns, each tool has a single responsibility, and tools are designed to chain naturally (enrichMatch, enrichGroup helpers). Key weaknesses: some output schemas are not explicitly documented in the source (inferred from implementation), error handling lacks detailed recovery guidance in most tools, and no explicit permission gating or audit logging visible. The schema quality is above-average but not exceptional, all 12 tools have visible input schemas with types, descriptions, and constraints.

• Add explicit output schema documentation to all tools. For example, get_matches should document: 'Returns array of match objects with: id, date, time_utc, home_team_id, home_team_name, away_team_id, away_team_name, venue_id, venue_name, venue_timezone, time_venue, [time_local, local_date, local_timezone if timezone param provided], group, round, status, score_home, score_away.'
• Enhance get_odds to accept optional parameters (e.g., category: 'winner'|'golden_boot'|'group'|'dark_horse', limit: number) to allow agents to request specific prediction types instead of always returning all odds.
• Add comprehensive error handling with actionable recovery guidance. Example for invalid timezone: 'Invalid timezone "UTC+1". Use IANA format: America/New_York, Europe/London, Asia/Tokyo. Call list_timezones() to see all supported formats.' Pattern: pattern:recovery-guide.
• Implement optional pagination for tools that return large result sets (get_matches, get_news, get_fan_zones). Add 'limit' (default 20, max 100) and 'offset' parameters with responses including 'total_count' and 'has_more' fields to prevent context window overflow.
• Standardize team parameter descriptions: 'Team ID, FIFA code, or name (e.g., usa, BRA, Argentina). Resolved case-insensitively.' Apply consistently across get_team_profiles, get_historical_matchups, get_visa_info, get_news, get_injuries.
• Add scope declarations to each tool (e.g., 'Requires: read:world-cup-data') for audit logging and least-privilege agent configuration. All tools are read-only; document this requirement clearly.
