What is webflow-mcp:link-checker?

A Webflow site audit tool that checks links across pages and CMS content, including whether links are broken or use insecure HTTP addresses. A CMS is the system that stores reusable website content such as articles or products.

Use it to review internal and external links, find broken or insecure URLs, fix links on static pages, and update links in CMS items.

It helps find link problems that may be missed when checking pages one at a time. It can identify issues in both regular pages and stored CMS content, then update affected links.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00046	$0.07607
Opus 5	$0.00023	$0.03803
Sonnet 5	$0.00009	$0.01521
Haiku 4.5	$0.00005	$0.00761

Security

Grade A, and why

webflow-mcp:link-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Audit and fix broken or insecure links across your Webflow site to improve SEO and user experience.

Important Note

ALWAYS use Webflow MCP tools for all operations:

Use Webflow MCP's webflow_guide_tool to get best practices before starting
Use Webflow MCP's data_sites_tool with action list_sites to identify available sites
Use Webflow MCP's data_sites_tool with action get_site to retrieve site details
Use Webflow MCP's data_pages_tool with action list_pages to get all pages
Use Webflow MCP's data_pages_tool with action get_page_content to extract links from static pages
Use Webflow MCP's data_pages_tool with action update_static_content to fix links on static pages
Use Webflow MCP's data_cms_tool with action get_collection_list to get all CMS collections
Use Webflow MCP's data_cms_tool with action get_collection_details to get collection schemas
Use Webflow MCP's data_cms_tool with action list_collection_items to get CMS items with links
Use Webflow MCP's data_cms_tool with action update_collection_items to fix links in CMS (draft)
Use Webflow MCP's data_cms_tool with action publish_collection_items to publish fixed CMS items
DO NOT use any other tools or methods for Webflow operations
All tool calls must include the required context parameter (15-25 words, third-person perspective)
No Designer connection is required — both static page and CMS link fixes go through data_ tools

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
