Content Genie MCP server

content-genie-mcp

Korean-content-creator MCP that gives Claude live Naver/Daum/Google/YouTube/Zum trends, a 100+ Korean-holiday DB, and a viral-score predictor — so you stop tab-hopping between 5 trend dashboards before every post.

Why content-genie?

Most "trend" MCPs are thin wrappers around Google Trends. If you're publishing for a Korean audience (Naver Blog, YouTube Korea, Instagram KR, TikTok), Google alone misses the signal — Naver Datalab, Daum search, Zum realtime, and KR-region YouTube each surface different keywords at different hours. content-genie consolidates all five sources into one MCP, layers a 100+ Korean-holiday + 14일-day-series + 절기 event database so Claude can plan around 빼빼로데이 and 수능 without being told, and finishes the loop with a viral-score predictor trained on the structural patterns (numbers, brackets, emotional triggers, urgency words) that move CTR in Korean content.

The Phase 4 refactor (v2.12.0, May 2026) made the whole thing safe to depend on: every scraper sits behind a per-source circuit breaker (3 fails → open 5 min) with a stale-cache fallback, so a Naver HTML change no longer takes the whole MCP down — it just degrades that one source and tells the LLM about it via resource://content-genie/sources.

What's new in v2.12.0

• 17 tools, one registry, six small files. The old 4,712-line index.ts is gone — tools live in src/tools/{trends,seo,contentIdeas,viralScoring,competitorAnalysis,koreanEvents}.ts. Adding a tool is a one-liner.
• Scrapers can't take the server down anymore. Per-source circuit breaker + LRU/TTL cache (15 min, 100 entries) + stale fallback. When Naver is degraded, Claude sees source_status: 'stale' and adapts.
• Two new MCP Resources for @-mention. resource://content-genie/korean-events/{year} returns the full event DB rebased to any year; resource://content-genie/sources exposes live breaker + cache state.
• Two MCP Prompts as guided workflows. viral-title chains optimizetitlehashtags → predictviralscore → generateabtest_variants. competitor-analysis does URL analysis + gap-filling ideation.
• 38 tests across 8 suites. Circuit breaker transitions, cache eviction, scraper fallback paths, SSRF guard, every tool group — runs on Node 20 + 22 in CI.

5-minute Quickstart

# 1. Install via Claude Code (recommended)
claude mcp add content-genie -- npx -y content-genie-mcp

# 2. Or add to Claude Desktop's claude_desktop_config.json:

{
  "mcpServers": {
    "content-genie": {
      "command": "npx",
      "args": ["-y", "content-genie-mcp"]
    }
  }
}

1. Restart Claude Desktop (or claude will pick it up on the next run).
2. Try this in Claude:

오늘 한국에서 뜨는 키워드 5개로 유튜브 쇼츠 제목 후보 3개씩 만들고, 각각 바이럴 점수 등급 매겨줘.

1. Expected: Claude calls getkoreantrends (naver+daum+google+youtube+zum merged) → optimizetitlehashtags per keyword → predictviralscore → returns a ranked S/A/B/C/D grade table with the structural reason ("제목에 숫자 + 호기심 트리거 포함").
