Schema.org is brilliant for what it was designed for: helping search engine crawlers understand the content of HTML pages. When you add LocalBusiness schema to your website, Google can extract your business name, address, hours, and ratings from the page markup.
But AI agents do not crawl HTML pages. They make API calls. They use MCP tool connections. They query structured data sources. Asking an AI agent to parse Schema.org from an HTML page is like asking a modern application to parse data from a printed PDF — technically possible, but architecturally wrong.
