FCritical

Mayo Clinic's website completely blocks AI agents with a 403 Forbidden error, forcing them to rely entirely on external search results.

Projected from the audit record. After fixing, re-run the task or re-measure to confirm.

AI agents are entirely blocked from accessing the Mayo Clinic website, encountering a 403 Forbidden error on the homepage and all standard agent-facing files. Because the site's Web Application Firewall (WAF) or bot protection intercepts these requests, agents cannot read any internal content. Consequently, across all ten tested tasks, the agents failed to cite any of the site's own URLs. Instead, they were forced to rely on external search engines and third-party knowledge to answer queries about bookings, locations, and policies. Until the blocking rules are adjusted to permit legitimate AI agents, the site will remain invisible to automated assistants.

WebMCP — what the site declares about itself

Not checked

This audit ran with the WebMCP check switched off. That does not mean there are no tools — it means we did not look. Turn on "Check WebMCP" when re-auditing.

Act-stage check (nothing submitted)

Checks whether an agent could fill in the forms and press the buttons, up to the point of pressing. No form was submitted, nothing added to a cart, nothing paid. Report only; not scored.

The act stage was not checked in this audit.
