Details

Waldium is a YC-backed startup that has developed an agentic CMS for businesses. The platform automates content research and generation, and provides an MCP (Model Context Protocol) server endpoint on every customer blog, allowing AI agents to query the data directly.

Recently, developers have been using blog content directly as context in tools like Claude Desktop or ChatGPT. By giving every blog an MCP endpoint, Waldium designed the system so that AI agents can instantly search for and answer specific code snippets or information without leaving the user's workflow.

To efficiently manage hundreds of customer blogs, custom domains, and branded MCP servers, Waldium adopted Vercel for Platforms. Through a single deployment based on Next.js, they achieved the following results:

  • Serving 500+ customer blogs from a single Vercel deployment
  • Using Vercel Middleware for dynamic routing that automatically connects AI queries to the appropriate tenant
  • Using the Vercel Domains API to provision custom domains and SSL in seconds
  • Cutting infrastructure costs by 45% and keeping global AI query response times under 50ms
