Agent-ready CMSs
We scanned 12 content management systems for websites and apps, including headless CMSs the way an AI agent would, and scored how well ChatGPT, Claude and Perplexity can read each one, sign a team up and connect through the API.
Which CMS is best for AI agents?
It depends on what you need agents to do. If you want an agent to sign your team up and connect through the API, Webflow scores highest (87/100), followed by Prismic (87) and Strapi (84). Webflow, Prismic, Storyblok, Sanity, Builder.io and Hygraph run remote MCP servers agents can connect to directly. Hygraph, WordPress.com and Contentful block AI agents with a bot wall, so assistants can't read their sites at all. Scores as of 20 Oct 2026.
