Securitytrails for AI agents

SecurityTrails provides domain, IP, DNS, and WHOIS intelligence, including historical records, used by security teams for threat hunting and brand protection. 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 Securitytrails connects.

Users add their Securitytrails 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 Securitytrails 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

Securitytrails and Arc0, answered.

Q01

Can I use Securitytrails with Claude, ChatGPT or Cursor?

Yes. Connect Securitytrails 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 Securitytrails actions you allow.

Q02

How do users connect Securitytrails?

Users add their Securitytrails 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 Securitytrails actions can my agent take?

12 in total: 6 read, 6 write and 0 destructive, such as “scroll Results”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Securitytrails?

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

Q05

Can my own backend call Securitytrails too?

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