Cricket-mcp has well-structured tool definitions with clear naming (verb_noun pattern) and comprehensive descriptions (avg 180 chars). All 11 tools have input schemas with typed parameters. However, parameter descriptions are sparse or missing in several tools (e.g., get_match_detail, get_match_state lack descriptions for league_id/event_id). Output schemas are not documented, LLMs cannot predict response structure. Error handling is absent; no recovery guidance or actionable error messages. Tool composition is sound (single responsibility), but missing pagination/limits guidance for list_live_matches. No security considerations visible (credentials, rate limits, input validation).

• Document output schemas for all 11 tools. Specify field names, types (string, integer, object, array), and nesting. Example: list_live_matches returns [{id: string, title: string, league: string, status: string}, ...]. This enables LLMs to chain tools correctly.
• Add descriptions to all parameters. For league_id and event_id, specify format (e.g., 'ESPN league identifier, e.g., "t20"'), valid values, and how to obtain them (e.g., 'from list_live_matches result').
• Add error handling guidance. Document what happens when league_id/event_id is invalid, network fails, or match has no data. Return actionable errors: 'Match not found. Call list_live_matches() to see available matches.'
• Clarify tool relationships. Document when to call get_match_detail vs get_match_state (e.g., 'get_match_detail for raw ESPN data; get_match_state for structured innings state'). Prevent redundant calls.
• Add pagination to list_live_matches. Document result limit (e.g., 'Returns up to 20 live matches; use offset/limit for more'). Include total count in response so agents know if more results exist.
