Workday for AI agents

Workday is enterprise HR and finance software, used by large organizations to manage employee records, compensation, and business processes. 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.

  1. 01Your users connect WorkdayThey sign in to Workday on Arc0 Connect, under your brand, and approve the access you ask for.
  2. 02You set the rulesReads run, writes like “create Case” can wait for the user, and “delete Custom Object” can be denied outright.
  3. 03Any agent can actYour agent calls Workday 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('workday', {
  read: 'allow',
  write: 'ask',        // create_case

04 · AUTH AND DATA

How Workday connects.

Users sign in to Workday on Arc0 Connect and approve the scopes you request. Build with Arc0’s Workday OAuth app, or bring your own so the Workday consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Workday 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

Workday and Arc0, answered.

Q01

Can I use Workday with Claude, ChatGPT or Cursor?

Yes. Connect Workday 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 Workday actions you allow.

Q02

How do users connect Workday?

Users sign in to Workday on Arc0 Connect and approve the scopes you request. Build with Arc0’s Workday OAuth app, or bring your own so the Workday consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Workday actions can my agent take?

587 in total: 423 read, 144 write and 20 destructive, such as “create Case”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Workday?

Yes. Actions like “delete Custom Object” 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 Workday too?

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