Personio for AI agents
Personio centralizes HR data including employee records, attendance, absences, and documents. HR teams use it as the system of record for people operations. 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 Personio.
Check an employee's absence record
Look up absence periods for an employee read-only before approving new time off.
Review attendance data
Pull attendance periods for a team to check for irregularities before payroll runs.
List employee documents read-only
Check what documents are on file for an employee without modifying their record.
10 Personio actions, graded by risk.
Every Personio action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Personio in three steps.
- 01Your users connect PersonioThey add their Personio oauth 2.0 client credentials on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, and writes like “updates” can wait for the user to approve.
- 03Any agent can actYour agent calls Personio through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('personio', { read: 'allow', write: 'ask', destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Personio connects.
Connect Personio with a service credential for your workspace. Arc0 keeps it in the vault, exchanges it for short-lived tokens, and never passes it to the model.
The same Personio 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
- OAuth 2.0 client credentials
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Personio from any agent.

Personio and Arc0, answered.
Can I use Personio with Claude, ChatGPT or Cursor?
Yes. Connect Personio 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 Personio actions you allow.
How do users connect Personio?
Connect Personio with a service credential for your workspace. Arc0 keeps it in the vault, exchanges it for short-lived tokens, and never passes it to the model.
Which Personio actions can my agent take?
10 in total: 10 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.
Can I make my agent read-only in Personio?
Yes. Allow read actions and deny writes in the Personio policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Personio too?
Yes. The same Personio connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Personio into your agent.
Your users connect Personio once, under your brand. Your agent gets 10 actions behind your policies, with every call on the record.
