## Description

The Canonical Checker MCP helps you find the source of truth for your web links. If you're managing a site with thousands of pages, it's easy for search engines to get confused by different versions of the same URL. This Connector lets you quickly figure out which version should be the primary one. Instead of manually squinting at strings of text, you can ask your AI client to look at a list of links. It handles the heavy lifting of comparing protocols, hostnames, and trailing slashes. It even separates the useful parts of a URL from the junk like tracking IDs. It's a huge time-saver for anyone trying to clean up a messy site structure or prepare for a migration. You can use it to spot inconsistencies that lead to duplicate content penalties or to standardize your hostnames across a whole domain. Whether you are auditing a new site or fixing an old one, this tool makes sure your web standards stay clean. By ensuring every page has one clear home, you save your crawl budget and keep your search rankings healthy. If you're looking for a reliable way to manage web standards without the headache, this is a solid addition to your Vinkius catalog.

## Tools

### audit_url_consistency
Compare a group of URLs to find protocol or slash mismatches. This helps you identify site-wide structural errors.

### identify_canonical_candidate
Find the most standard version of a URL for your canonical tags. This helps search engines know which page is the original.

### detect_parameter_drift
Show which query parameters are causing your URLs to vary. Use this to separate tracking junk from static links.

## Prompt Examples

**Prompt:** 
```
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?
```

**Response:** 
```
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.
```

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

**Response:** 
```
**Discrepancies detected:**
* Protocol mismatch (HTTP vs HTTPS)
* Trailing slash inconsistency
```

**Prompt:** 
```
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
```

**Response:** 
```
**Variable parameters found:**
* utm_medium
* sessionid

**Static parameters found:**
* q
```

## Capabilities

### Find the best canonical URL
Identify the primary link for your content to prevent duplicate content issues.

### Spot structural differences in link groups
Compare multiple URLs to find discrepancies in protocols or slashes.

### Separate tracking parameters from static URLs
Identify which query parameters are causing your links to vary.

### Detect protocol and hostname mismatches
Check for inconsistent use of HTTPS and www vs. non-www hostnames.

### Audit URL consistency across a sitemap
Scan large groups of links to ensure they follow your site's standards.

## Use Cases

### Picking a primary page from a list of variations
An SEO specialist finds 50 variations of a product page and needs to pick the primary one to avoid duplicate content penalties.

### Verifying URL consistency during an HTTPS move
A developer moves a site to HTTPS and needs to verify all links are consistent across the entire domain.

### Isolating UTM tags from static URLs
A marketing manager wants to see which UTM tags are causing unique URL issues and which parts of the URL remain static.

### Cleaning up sitemaps for better crawling
A content manager wants to ensure they aren't creating duplicate pages for the same topic before submitting a sitemap.

## Benefits

- Stop duplicate content penalties by using identify_canonical_candidate to pick the right links for every page.
- Save hours of manual auditing with audit_url_consistency to find site-wide errors in seconds.
- Clean up messy tracking by using detect_parameter_drift to isolate variable parameters from static URLs.
- Ensure consistent branding by standardizing www vs. non-www hostnames across your entire domain automatically.
- Improve crawl efficiency by fixing protocol mismatches between HTTP and HTTPS using automated checks.

## How It Works

The bottom line is you get a standardized list of authoritative URLs without the manual audit work.

1. Provide a list of URLs to your AI client.
2. The Connector analyzes each link for protocol, hostname, and parameter consistency.
3. You get a clear report of the best canonical candidate and any detected discrepancies.

## Frequently Asked Questions

**How does Canonical Checker help with duplicate content?**
It identifies the most authoritative version of a URL among many variations. This helps search engines understand which page is the original, preventing your site from being penalized for having the same content on multiple links.

**Can Canonical Checker handle UTM parameters?**
Yes, it can separate your static URLs from variable tracking parameters. This helps you see how much 'noise' is being added to your links by marketing tools.

**Will Canonical Checker find my HTTP vs HTTPS errors?**
It will. The tool audits a group of URLs to find protocol mismatches. You'll get a clear list of every link that isn't using the secure version of your site.

**Can I use Canonical Checker to fix my sitemap?**
While it doesn't edit your sitemap files directly, it tells you exactly which URLs are consistent and which aren't. You can then use that data to clean up your sitemap and improve how search engines crawl your site.

**Is Canonical Checker good for large site audits?**
It's built for exactly that. You can feed it large groups of URLs, and it will highlight structural discrepancies like missing trailing slashes or inconsistent hostnames across the whole set.

**How does the tool identify a canonical URL?**
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.

**Can I detect tracking parameters?**
Yes, using `detect_parameter_drift`, you can identify which query parameters are variable (like UTM or session IDs) and which are static across your URL list.

**What kind of discrepancies does the audit tool find?**
The `audit_url_consistency` tool flags mismatches in protocol, subdomain usage (www vs non-www), trailing slashes, and parameter counts.
