Case 1: No Issues Found
🎉 Excellent! No Issues Found
All 247 links are working correctly!
Health Score: 100/100 ✨
Your site has:
✅ No broken links
✅ No insecure HTTP links
✅ No unnecessary redirects
💡 Recommendation:
Run this check monthly to maintain link health.
Case 2: All Links Broken
❌ Critical: Multiple Broken Links
Found 89 broken links across all pages.
This suggests a possible site-wide issue:
- Domain migration not configured?
- External service outage?
- Relative URL path issues?
🔍 Recommended Action:
1. Check if external services are down
2. Verify domain and SSL configuration
3. Test a few links manually
4. Contact Webflow support if needed
Shall I still proceed with individual link fixes? (yes/no)
Case 3: Mixed HTTP/HTTPS Site
⚠️ Mixed Content Warning
Your site uses HTTPS but has 18 HTTP links.
This creates:
- Security warnings in browsers
- SEO penalties
- Trust issues for visitors
🔧 Recommendation:
Upgrade all HTTP links to HTTPS (all 18 can be auto-fixed)
Proceed with upgrade? (yes/no)
Case 4: Redirect Chains
⚠️ Redirect Chain Detected
Link: https://example.com/old
→ 301 to: https://example.com/temp
→ 301 to: https://example.com/final
Recommendation: Update directly to final URL
- Improves page load speed
- Reduces redirect overhead
- Better for SEO
Fix: Update to https://example.com/final
Apply fix? (yes/no)
Before considering link checker implementation complete:
Run comprehensive accessibility audit (WCAG 2.1) on Webflow pages - checks buttons, forms, links, focus states, headings, keyboard navigation, and generates detailed reports with fixes. Runs entirely headlessly against a page ID — no Designer connection required. Excludes image alt text (covered by asset-audit skill).
Build and manage pages, elements, components, and styles in Webflow Designer. Use when adding sections, creating layouts, building elements, inspecting or updating components, viewing what's inside a component, restructuring pages, creating new pages, previewing page structure, styling elements, or managing component properties. Building, styling, and inspecting run headlessly against an explicit page ID — no Designer connection needed. Designer is required for `designer_tool` actions (reading/switching the page open on canvas, interactively selecting an element, creating page folders, opening a component's canvas view) and for `element_snapshot_tool` visual previews.
Apply Flowkit CSS naming system in Webflow. Use when creating classes, auditing existing naming, or building new components following Flowkit conventions. Flowkit is Webflow's official CSS framework with utility-first approach. Runs headlessly against a page ID — no Designer connection required, except for the optional live-canvas conveniences (current page, interactive element selection).
Analyze assets on a Webflow site for SEO optimization. Identifies assets missing alt text and assets with non-SEO-friendly names, then generates and applies improvements.
A Webflow University guided onboarding skill for anyone getting started with the Webflow MCP. Checks your Webflow connection, helps you choose a real workflow to try, coaches prompt writing, and supports you through your first MCP run.
Compress and convert CMS item image fields to webp or avif in a Webflow collection. Prompts for collection ID, item ID, image fields, quality, and target format, then downloads, converts, re-uploads via presigned S3, and publishes the updated item.
