V0 for AI agents

v0 is Vercel's AI tool for generating production-ready web code from a prompt, used by developers who want a working component or page to start from. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

EVERY V0 CALL, ON THE RECORD

01 · USE CASES

What agents do in V0.

Generate code from a prompt

Ask v0 to build a component or page and get back working code.

Find an existing chat or project

Look up a previous v0 chat or project as a read-only search before continuing it.

Confirm before deploying a project

Get approval before deploying generated code, since a deployment makes it publicly reachable.

02 · ACTIONS

44 V0 actions, graded by risk.

Every V0 action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

V0 in three steps.

01Your users connect V0They add their V0 api key on Arc0 Connect, under your brand. It goes straight into the vault.
02You set the rulesReads run, writes like “create Webhook” can wait for the user, and “delete Chat” can be denied outright.
03Any agent can actYour agent calls V0 through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

POLICY.TS

await arc0.policies.set('v0', {
  read: 'allow',
  write: 'ask',        // create_hook_v0
  destructive: 'deny',  // delete_chat
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How V0 connects.

Users add their V0 api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same V0 connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

AUTH: API key
CREDENTIALS: Per-tenant encrypted vault
MODEL SEES: Results only, never credentials

07 · FAQ

V0 and Arc0, answered.

Q01

Can I use V0 with Claude, ChatGPT or Cursor?

Yes. Connect V0 to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the V0 actions you allow.

Q02

How do users connect V0?

Users add their V0 api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which V0 actions can my agent take?

44 in total: 24 read, 15 write and 5 destructive, such as “create Webhook”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in V0?

Yes. Actions like “delete Chat” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call V0 too?

Yes. The same V0 connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
