Server has 7 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have input schemas with type definitions and descriptions present, meeting minimum baseline. However, descriptions are often generic (e.g., 'Check which APIs are configured and available' for api_status is only 52 chars, below the 194-char production average). Output schemas are completely undocumented, LLMs cannot predict response structure. No error handling guidance (e.g., 'If Naver API fails, try again in 5 minutes' or 'Check api_status to verify credentials'). Parameter constraints lack specificity: 'max 5' keywords and 'max 20' results are mentioned in descriptions but not enforced via JSON Schema enums/maxItems. No pagination support despite search tools returning lists. Tool composition is reasonable (each does one thing), but research_topic combines 4 APIs into one call, risking cascading failures with no partial-result fallback. Security: API keys are injected via .env (good), but no audit logging or permission gates visible. Naming follows verb_noun convention (search_blogs, translate_text), solid. Missing: output field documentation, error recovery paths, rate-limit guidance, and idempotency markers.

• Document output schemas for all tools. E.g., api_status should return {status: {naver: 'ok'|'missing', unsplash: 'ok'|'missing'}, message: string}. search_blogs should return {results: [{title, author, date, url, summary}], total_count, query}.
• Add error recovery guidance to descriptions. E.g., 'If Naver API returns 401, verify NAVER_CLIENT_ID and NAVER_CLIENT_SECRET in .env. Call api_status() to check configuration.' Pattern: recovery-guide.
• Enforce parameter constraints in JSON Schema: add maxItems: 5 to trend_keywords.keywords, maximum: 20 to search_blogs.count, etc. Do not rely on description text alone.
• Split research_topic into separate tools or add graceful degradation: if one API fails, return partial results (e.g., trends + blogs but no images) with a 'partial_failure' flag. Prevents cascading failures.
• Add pagination to search_blogs, search_news, search_images: accept offset/limit params, return total_count and next_offset. Cap default results at 5, max at 20 to prevent context explosion.
