AbuseIPDB for AI agents
AbuseIPDB is a shared database for reporting and checking IP addresses tied to malicious activity. Security teams use it to screen traffic and flag abusive sources. 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.
What agents do in AbuseIPDB.
Check an IP's reputation
Look up whether an IP address has a history of abuse before allowing it through a firewall rule.
Report an abusive IP
Submit a report flagging an IP address for malicious activity, a write action added to the shared blacklist.
Clear reports on an address
Remove existing abuse reports tied to an IP address, a step that should be confirmed before it's cleared.
6 AbuseIPDB actions, graded by risk.
Every AbuseIPDB action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

AbuseIPDB in three steps.
- 01Your users connect AbuseIPDBThey add their AbuseIPDB api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “retrieve IP Blacklist” can wait for the user, and “check Block” can be denied outright.
- 03Any agent can actYour agent calls AbuseIPDB through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('abuseipdb', { read: 'allow', write: 'ask', // blacklist destructive: 'deny', // check_block }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How AbuseIPDB connects.
Users add their AbuseIPDB 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 AbuseIPDB 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

AbuseIPDB and Arc0, answered.
Can I use AbuseIPDB with Claude, ChatGPT or Cursor?
Yes. Connect AbuseIPDB 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 AbuseIPDB actions you allow.
How do users connect AbuseIPDB?
Users add their AbuseIPDB 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.
Which AbuseIPDB actions can my agent take?
6 in total: 2 read, 2 write and 2 destructive, such as “retrieve IP Blacklist”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in AbuseIPDB?
Yes. Actions like “check Block” 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.
Can my own backend call AbuseIPDB too?
Yes. The same AbuseIPDB connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug AbuseIPDB into your agent.
Your users connect AbuseIPDB once, under your brand. Your agent gets 6 actions behind your policies, with every call on the record.
