Malwarebytes for AI agents
Malwarebytes provides threat intelligence lookups that check links, emails, phone numbers, and domains for known malicious activity before they reach a user. 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.

How Malwarebytes connects.
Malwarebytes needs no credentials. Arc0 still applies your policies and records every call, so public tools get the same controls as private ones.
The same Malwarebytes 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
- No auth
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES

Malwarebytes and Arc0, answered.
Can I use Malwarebytes with Claude, ChatGPT or Cursor?
Yes. Connect Malwarebytes 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 Malwarebytes actions you allow.
How do users connect Malwarebytes?
Malwarebytes needs no credentials. Arc0 still applies your policies and records every call, so public tools get the same controls as private ones.
Which Malwarebytes actions can my agent take?
6 in total: 0 read, 6 write and 0 destructive, such as “reputation-whois”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Malwarebytes?
Yes. Allow read actions and deny writes in the Malwarebytes policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Malwarebytes too?
Yes. The same Malwarebytes connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Malwarebytes into your agent.
Your users connect Malwarebytes once, under your brand. Your agent gets 6 actions behind your policies, with every call on the record.
