Whispering Wombat
a crawler that reads your site like Google does.
An SEO site crawler we built as a Screaming Frog replacement that lives on Cloudflare: it crawls a whole site, finds the technical SEO problems, and reports them back. It already powers the Whispering Wombat SEO server in our MCP catalogue, so an AI can run a crawl and read the findings for you.
// sound familiar?
The standard SEO crawlers are desktop apps: one machine, one person, nothing an AI or a teammate can pick up. We wanted a crawler that lived on the edge and could be driven by an agent.

What it does
Whole-site crawl
Walks every page, following links the way a search engine would, and records what it finds.
Technical SEO findings
Surfaces the issues that actually move rankings: broken links, missing or duplicate metadata, thin content, sitemap gaps.
Built to run itself
A Durable Object orchestrates the crawl with alarm chaining, so big sites finish without timing out.
AI can drive it
Exposed through MCP, so an agent can start a crawl, wait for it, and explain the issues in plain English.
- A crawl any teammate (or AI) can run, not just whoever has the desktop licence
- Technical SEO issues found and explained, not just listed
- The same engine usable from chat through MCP
// is this you?
Built for us, and the SEO work we do for clients: a crawler we own and can wire into anything.
Not for you if you want a polished, sign-up-and-go SEO dashboard today. This is the engine; the friendly front end is the MCP server.
// the build log
A proof of concept that earned its keep
Built Feb to April 2026 to see whether a serverless crawler could replace a desktop SEO tool. It could, and it became the engine behind the Whispering Wombat MCP server.
