Inputs

• domain: The bare domain to analyze (e.g., example.com). Strip https://, http://, and trailing slashes before passing to Ahrefs tools.

MCP Check

Before proceeding, verify Ahrefs MCP is available:

1. Use ToolSearch with query +ahrefs
2. If tools are returned → Ahrefs MCP is available, proceed to Execution
3. If no tools returned → display the Ahrefs MCP error template from references/mcp-degradation.md and stop

Execution

Step 1 — Call Domain Rating History

Call mcp__claude_ai_ahrefs__site-explorer-domain-rating-history with:

• target: the bare domain (e.g., example.com)

Returns per data point: date (ISO 8601), domain_rating (0–100), ahrefs_rank

Step 2 — Sort and Analyze

• Sort data points by date descending (most recent first)
• Calculate overall trend: compare first (oldest) and last (most recent) DR values
  • "DR increased by X points over the last Y months"
  • "DR decreased by X points over the last Y months"
  • "DR stable (±2 points) over the last Y months"

Step 3 — Flag Significant Changes

Scan consecutive data points for swings >5 DR points in a single month:

• Mark these as noteworthy events: "Significant DR drop of X points in [month]" or "Significant DR gain of X points in [month]"
• These warrant investigation (algorithm update, major link acquisition/loss, toxic backlink removal, etc.)
