Open Page Rank (Kevin's DA proxy)

A free domain-authority proxy. Requires OPENPAGERANK_API_KEY (free tier: 1,000 requests/day at https://www.domcop.com/openpagerank/).

⚠️ What this is NOT

Open Page Rank is not Moz Domain Authority. It uses its own algorithm and scores are not comparable to DA. Use it for:

• ✅ Trend tracking — "did our score move up over 6 months?"
• ✅ Relative comparison — "how does NN compare to competitor X?"
• ❌ Absolute benchmarking — "is NN DA 30 or 35?" (don't use this for that)

For an absolute Moz DA number, You can paste it manually from Moz's free web checker once a month.

Commands

rank <domain>...

Pass one or more bare hostnames (no https://, no trailing slash). Returns one row per domain.

# Single domain
mcp__plugin_agent-kevin_kevin__open_page_rank rank example.com

# Multiple domains (competitive check)
mcp__plugin_agent-kevin_kevin__open_page_rank rank example.com competitor-a.com competitor-b.com

Return shape:

[
  {
    "domain": "example.com",
    "page_rank_integer": 4,
    "page_rank_decimal": 4.21,
    "rank": "12345678",
    "found": true
  }
]

• page_rank_integer — 0–10 scale, rounded. Quick read.
• page_rank_decimal — same scale with 2 decimals. Use this for trend tracking (catches small changes between months).
• rank — global rank among all indexed domains (lower = better).
• found — false if the domain isn't indexed. Score fields are null in that case.

Common patterns

Monthly NN score (for analytics report):

mcp__plugin_agent-kevin_kevin__open_page_rank rank example.com | jq '.[0].page_rank_decimal'

Competitive authority comparison:

mcp__plugin_agent-kevin_kevin__open_page_rank rank example.com competitor-a.com competitor-c.com competitor-d.com \
  | jq 'sort_by(-.page_rank_decimal) | .[] | {domain, score: .page_rank_decimal}'

When to use vs not

• ✅ Monthly trend snapshot for the NN analytics report.
• ✅ Quick sanity check of a new competitor's authority before deep analysis.
• ❌ Anything requiring Moz-comparable numbers (outreach, publisher pitches, backlink-gap analysis).
• ❌ Per-page authority (this is domain-only; OPR doesn't do page-level).
