Binary: keyword-steroids-gold · Package: keyword-steroids-gold · MCP name: ai.studio/keyword-steroids-gold

Disclosure: This project is an independent Gold wrapper around public Google endpoints and official APIs. No-key tools use the public Google Suggest endpoint (https://suggestqueries.google.com/complete/search?client=firefox&q=...&hl=iw&gl=il — no key — and https://www.google.com/search?q=...&hl=iw&gl=il HTML scrape for Related/PAA). GSC tools use the official Google Search Console API (https://developers.google.com/webmasters/search-console-api — https://www.googleapis.com/webmasters/v3/sites/... + /searchAnalytics/query) via BYOK GSC_OAUTH_JSON (and optional BigQuery https://cloud.google.com/bigquery/docs via BIGQUERY_OAUTH_JSON). Semrush gap uses the official Semrush API (https://www.semrush.com/api-documentation/ — https://api.semrush.com/?type=domain_organic...) via BYOK SEMRUSH_API_KEY. We are not affiliated with Google LLC or Semrush. Use only on your own sites/domains — you provide your own keys via BYOK (Bring Your Own Keys). We never see or store your keys.

Buy Pro — PAID ONLY $29 once via Keygen CE (no free tier): https://gumroad.com/l/keyword-steroids-gold — all 9 gold_* tools require GOLD_LICENSE_KEY, fail-closed without it (offline 7-day grace). gold_setup_check runs without a license to verify your BYOK keys.

Quick start

npx -y keyword-steroids-gold
# or local
npm install
npm run build
node dist/index.js

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "keyword-steroids-gold": {
      "command": "npx",
      "args": ["-y", "keyword-steroids-gold"],
      "env": {
        "GOLD_LICENSE_KEY": "gold_pro_...",
        "GSC_OAUTH_JSON": "{\"type\":\"service_account\",...}",
        "SEMRUSH_API_KEY": "semrush_xxx",
        "BIGQUERY_OAUTH_JSON": "{\"type\":\"service_account\",...}"
      }
    }
  }
}

Without GSC/Semrush keys, no-key tools still work. GSC/Semrush tools return config_error without their key — no fake data.

Env vars (BYOK — no fake data, fail-closed)

gold_setup_check always runs and only reports key names SET/MISSING (never values). No-key tools throttle 1.2s and never call GSC/Semrush.

Honest BYOK / no-key split

• No key (public, free, 1.2s throttle): gold_keyword_expand, gold_keyword_gap_scan, gold_cluster (pure logic), gold_crawl_audit, gold_keyword_brief, gold_keyword_serp_features — work with no API key (Google Suggest suggestqueries.google.com/complete/search + HTML scrape google.com/search + pure Jaccard/crawl).

• BYOK (fail-closed): gold_gsc_verify + gold_gsc_insights require GSC_OAUTH_JSON; gold_gsc_insights with bigquery_sql requires BIGQUERY_OAUTH_JSON; gold_semrush_gap requires SEMRUSH_API_KEY. Each throws config_error without the key.

Tools (gold_* — 9 tools + gold_setup_check = 10, all PRO $29 — plus gold_setup_check runs without license)

All 9 tools are gold_* prefixed — PAID ONLY PRO $29 once, fail-closed without GOLD_LICENSE_KEY. Destructive writes are not applicable (read/analysis only). Env mapping is GSC_OAUTH_JSON / SEMRUSH_API_KEY / BIGQUERY_OAUTH_JSON ↔ smithery.yaml gscOauthJson / semrushApiKey / bigqueryOauthJson.

Self-check is pure logic: gold_setup_check counts keys SET/MISSING (names only, never values), reports tier, never calls Google/Semrush, never leaks tokens — verified by grep fetch|GSC_OAUTH|SEMRUSH.
