Chatwork for AI agents

Chatwork is a business chat platform combining group messaging, file sharing, and task tracking, aimed at teams that want collaboration without separate tools. 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.

  read: 'allow',
  write: 'ask',        // create_room
  destructive: 'deny',  // delete_room
})

04 · AUTH AND DATA

How Chatwork connects.

Users add their Chatwork 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 Chatwork 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

Chatwork and Arc0, answered.

Q01

Can I use Chatwork with Claude, ChatGPT or Cursor?

Yes. Connect Chatwork 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 Chatwork actions you allow.

Q02

How do users connect Chatwork?

Users add their Chatwork 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 Chatwork actions can my agent take?

30 in total: 15 read, 12 write and 3 destructive, such as “create Chatwork Room”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Chatwork?

Yes. Actions like “delete or Leave Chatwork Room” 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 Chatwork too?

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