Soccer News MCP has 9 tools with complete input schemas and descriptions, but quality is uneven. Tool names follow verb_noun convention (fetch-feeds, search-news, analyze-sentiment). Descriptions are present but brief (avg ~60 chars, below the 194-char baseline). Parameter descriptions exist but lack detail on constraints, formats, and valid ranges. Output schemas are not documented, LLMs cannot predict response structure. Error handling is basic (generic error messages). No tool annotations (readOnlyHint/destructiveHint). Security: no secrets in params (good), but no permission gates or audit logging visible. Composition is reasonable, tools are single-purpose, but some lack chaining IDs in responses.

• Document output schemas for all 9 tools. Include field names, types, and examples. E.g., search-news returns [{id, title, url, sentiment, date, source}]. This enables agents to chain tools correctly.
• Add enum constraints to parameters. E.g., sentiment: enum ['positive', 'negative', 'neutral']; action: enum ['add', 'update', 'remove']; limit: integer, minimum 1, maximum 100. Replace free-form descriptions with formal constraints.
• Add tool annotations: mark search-news, list-sources, get-recent-news, ask-sir-alex, get-random-quote, get-quotes-by-topic with readOnlyHint=true. Mark fetch-feeds, manage-sources, analyze-sentiment with destructiveHint=true.
• Split manage-sources into three tools: create-source, update-source, delete-source. Each has a single responsibility, clearer error handling, and independent idempotency semantics.
• Enhance error messages with recovery guidance. E.g., 'Article ID 123 not found. Call list-sources first to verify source is active, then fetch-feeds to index articles.' This guides multi-step recovery.
