WhatsApp for AI agents
WhatsApp Business API sends and manages business messaging on WhatsApp, used by companies handling customer conversations, notifications, and templates at scale. 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.
What agents do in WhatsApp.
Get message templates
Pull approved message templates as a read-only check before sending a notification.
Get business profile details
Read the connected business account's profile information, like its display name and description.
Confirm before deleting a message template
Check with the user before deleting a template, since any automation using it would stop working.
58 WhatsApp actions, graded by risk.
Every WhatsApp action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

WhatsApp in three steps.
- 01Your users connect WhatsAppThey sign in to WhatsApp on Arc0 Connect, under your brand, and approve the access you ask for.
- 02You set the rulesReads run, writes like “create WhatsApp Flow” can wait for the user, and “delete WhatsApp Media” can be denied outright.
- 03Any agent can actYour agent calls WhatsApp through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('whatsapp', { read: 'allow', write: 'ask', // create_flow destructive: 'deny', // delete_media }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How WhatsApp connects.
Users sign in to WhatsApp on Arc0 Connect and approve the scopes you request. Build with Arc0’s WhatsApp OAuth app, or bring your own so the WhatsApp consent screen names you. Tokens refresh automatically, and you can export them whenever you want.
The same WhatsApp connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

WhatsApp and Arc0, answered.
Can I use WhatsApp with Claude, ChatGPT or Cursor?
Yes. Connect WhatsApp 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 WhatsApp actions you allow.
How do users connect WhatsApp?
Users sign in to WhatsApp on Arc0 Connect and approve the scopes you request. Build with Arc0’s WhatsApp OAuth app, or bring your own so the WhatsApp consent screen names you. Tokens refresh automatically, and you can export them whenever you want.
Which WhatsApp actions can my agent take?
58 in total: 25 read, 27 write and 6 destructive, such as “create WhatsApp Flow”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in WhatsApp?
Yes. Actions like “delete WhatsApp Media” 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.
Can my own backend call WhatsApp too?
Yes. The same WhatsApp connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug WhatsApp into your agent.
Your users connect WhatsApp once, under your brand. Your agent gets 58 actions behind your policies, with every call on the record.
