Exa for AI agents

Exa is a search and data extraction API that helps teams gather and structure information from websites and documents, used by developers building research and retrieval tools. 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 Exa.

01

Search the web for sources

Run a search to find sources relevant to a research question a user asked.

02

Pull content from a URL

02 · ACTIONS

20 Exa actions, graded by risk.

Every Exa action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

Exa in three steps.

  1. 01Your users connect ExaThey add their Exa api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Import” can wait for the user, and “delete import” can be denied outright.
  3. 03Any agent can actYour agent calls Exa through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('exa', {
  read: 'allow',
  write: 'ask',        // create_import

04 · AUTH AND DATA

How Exa connects.

Users add their Exa 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 Exa 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

Exa and Arc0, answered.

Q01

Can I use Exa with Claude, ChatGPT or Cursor?

Yes. Connect Exa 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 Exa actions you allow.

Q02

How do users connect Exa?

Users add their Exa 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 Exa actions can my agent take?

20 in total: 11 read, 7 write and 2 destructive, such as “create Import”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Exa?

Yes. Actions like “delete import” 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 Exa too?

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