Latest update (11-09 14:17): Vercel MCP opens to any MCP client via metadata documents

Overview: Vercel opens its MCP server to any MCP client, according to a post from its developer account on X. Clients no longer need to be allowlisted to request access. Instead, a developer hosts a JSON metadata file on their domain, and Vercel shows the client's name, logo and hostname on the consent screen.
