Faraday for AI agents

Faraday embeds predictive AI into a company's stack, using customer datasets and outcomes to power personas, cohorts, and targeting for marketing and growth teams. 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 Faraday.

01

Build a customer cohort

Create a cohort from a dataset once the marketing team defines a target audience.

02

Check a persona set's traits

Read a persona set's traits to see how customers are being segmented for a campaign.

03

Confirm before archiving a dataset

Require approval before archiving a dataset, since models and cohorts built on it may stop updating.

02 · ACTIONS

117 Faraday actions, graded by risk.

Every Faraday 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

Faraday in three steps.

  1. 01Your users connect FaradayThey add their Faraday api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Place” can wait for the user, and “delete Place” can be denied outright.
  3. 03Any agent can actYour agent calls Faraday 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('faraday', {
  read: 'allow',
  write: 'ask',        // create_place
  destructive: 'deny',  // delete_place
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How Faraday connects.

Users add their Faraday 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 Faraday 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

Faraday and Arc0, answered.

Q01

Can I use Faraday with Claude, ChatGPT or Cursor?

Yes. Connect Faraday 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 Faraday actions you allow.

Q02

How do users connect Faraday?

Users add their Faraday 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 Faraday actions can my agent take?

117 in total: 52 read, 42 write and 23 destructive, such as “create Place”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Faraday?

Yes. Actions like “delete Place” 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 Faraday too?

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