Charla for AI agents

Charla combines live chat and an AI-assisted knowledge base, letting a support team manage conversations and help articles from one place. 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.

04 · AUTH AND DATA

How Charla connects.

Users add their Charla 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 Charla connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Charla and Arc0, answered.

Q01

Can I use Charla with Claude, ChatGPT or Cursor?

Yes. Connect Charla 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 Charla actions you allow.

Q02

How do users connect Charla?

Users add their Charla 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 Charla actions can my agent take?

9 in total: 6 read, 2 write and 1 destructive, such as “create Knowledge Base Article”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Charla?

Yes. Actions like “delete Knowledge Base Article” 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 Charla too?

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