The Canonical Checker MCP server helps SEO professionals identify the single, cleanest version of a URL from multiple variations. By analyzing protocol consistency (HTTP vs HTTPS), hostname standardization (www vs non-www), trailing slash presence, and query parameter noise, it prevents duplicate content issues. Use identify_canonical_candidate to find the best canonical tag candidate, audit_url_equality to detect structural discrepancies in URL groups, and detect_parameter_drift to separate static from variable tracking parameters.

Which of these is the best canonical URL: https://mysite.com/page, http://www.mysite.com/page/, and https://mysite.com/page?utm_source=email?

The best canonical candidate is https://mysite.com/page because it uses the secure HTTPS protocol, has a standardized hostname without 'www', and contains no unnecessary query parameters.

Check these URLs for consistency: https://shop.com/item, https://shop.com/item/, and http://shop.com/item

Discrepancies detected: Protocol mismatch (HTTP vs HTTPS) and trailing slash inconsistency.

Analyze these URLs for parameter drift: https://mysite.com/search?q=shoes, https://myssite.com/search?q=shirts&utm_medium=social, and https://myssite.com/search?q=hats&sessionid=123

Variable parameters found: utm_medium, sessionid. Static parameters found: q.

The `identify_canonical_candidate` tool evaluates all provided URLs and selects the one with the fewest 'noise' elements, prioritizing HTTPS, standardized hostnames, and minimal query parameters.
