Winston AI for AI agents

Winston AI detects AI-generated text and plagiarism, used by educators and publishers checking whether content was written or copied rather than original. 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 Winston AI connects.

Users add their Winston AI 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 Winston AI 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
AUDIT LOG: Every call, on every plan

07 · FAQ

Winston AI and Arc0, answered.

Q01

Can I use Winston AI with Claude, ChatGPT or Cursor?

Yes. Connect Winston AI 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 Winston AI actions you allow.

Q02

How do users connect Winston AI?

Users add their Winston AI 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 Winston AI actions can my agent take?

3 in total: 0 read, 3 write and 0 destructive, such as “tEXT_COMPARE”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Winston AI?

Yes. Allow read actions and deny writes in the Winston AI policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Winston AI too?

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