What Vercel does
Provides mcp-handler, a framework-agnostic HTTP adapter for hosting MCP servers in JavaScript and TypeScript applications.
Why teams reach for it: Places an MCP server in the same deployment and domain as the application whose data it exposes.
Worth knowing
The mcp-handler adapter is open source; the hosting platform is a commercial service.

Where will the MCP server run?
Hosting & deployment tools are where an MCP server actually runs once it's built, usually a cloud platform.
