Connect Claude (desktop & claude.ai) to Vercel

Three steps

  1. Create a free 0n3 account and connect Vercel. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Claude (desktop & claude.ai). Add 0n3 as a custom connector; sign in once through the 0n door.
  3. Ask Claude (desktop & claude.ai): whoami. Then: "List projects in Vercel".
Claude desktop app and claude.ai
  1. Settings → Connectors → Add custom connector
  2. Name: 0n3 · URL: https://0n3.app/mcp
  3. Click Connect and sign in with your 0n account (email + password, or paste your 0n token)
  4. Turn the connector on in a chat and ask: "whoami"

This is the OAuth door: no token to paste, revoke it any time from 0n3 → Tokens.

The line above carries a placeholder; 0n3.app/install mints a real key named for Claude (desktop & claude.ai) and fills it in.
