WebMCP checker: can an AI agent use your site?
Enter a public page. The check looks for WebMCP implementation signals and the basics an agent needs before it can use any tool: access, readable content and a clear action. The result shows the evidence behind each finding and what to fix first.
One request, about 20 seconds. No sign-up, no email. The result gets a shareable address.
What the check examines
WebMCP signals
References to document.modelContext, tool registration, schemas and annotations in the page and accessible scripts.
Agent access
Whether the page responds to agent user agents, whether robots.txt permits access and whether useful content arrives without JavaScript.
Usable actions
Discoverable controls and forms, readable errors, and machine-readable ways for agents to find a service.
How to use the result
Start with a page where a visitor should complete a task, such as a product page or a form. Check the specific URL: a scan of your homepage does not test your checkout. Open the finding that failed, inspect its evidence and make the first fix before checking again. The scoring method explains every check and its weight.
This is a source-level check. It does not run your page in a browser, call a WebMCP tool or sign in as a user. A tool found in code still needs a live browser test. A tool registered only after login may be missed. See the Chrome setup guide to test registration in a browser, or read what WebMCP does first.
