Does this site declare WebMCP?

Enter a site. We read its robots.txt, then its page and first-party scripts, and tell you whether it declares WebMCP tools — and where we can run the page, whether any tool actually registers.

A check has no effect on any ranking or listing. This tool reads the site you name and nothing else; it does not add it to our index, change its position, or tell us anything we act on. What WebMCP is and how many sites implement it.

How this checks

• robots.txt first, every time. If a site's Content-Signal says ai-input=no we stop and report it as excluded — never as failing a check we did not run.
• Tools are listed, never invoked. Calling a stranger's tool could place an order or send a message.
• "Could not ask" is its own answer. A timeout, a rate limit or a script we could not read is reported as that, not as a no. Most checkers collapse the two, and always toward the confident negative.
• Declared is not registered. Code in the page proves a registration exists, not that anything registers.

This check is free, anonymous and not recorded. Behavioural verification is the dated, published version — a waitlist, not a purchase.
