More Apps Can Ask to Connect to Vercel

Vercel now lets more apps ask to connect to Vercel MCP. MCP is a way for AI apps to connect to tools. Before this change, Vercel checked every app itself. An app outside its allowed list could not connect at all. The new method removes that first check by Vercel.

An app now publishes a file on its own website. This file is called a Client ID Metadata Document, or CIMD. It contains information that describes the app asking for a connection. The app uses the file's web address to identify itself. This follows the connection rules that MCP now recommends for these requests.

Users still have to sign in and approve each connection themselves. The new method does not give an app access without that step. But users need to understand that Vercel has not checked it first. The permission screen shows the app's name, logo, and website name. That helps people see where the request for a connection comes from.

For example, the screen may show Claude Code with the website claude.ai. Apps using CIMD do not get Vercel's mark for checked apps. The website name therefore matters when a person decides to trust one. A logo and a name alone do not mean Vercel checked it. Apps already registered with Vercel are not changed by this update. The main change is a wider way to request access, with user approval.
