DaData.ru for AI agents

DaData validates and standardizes data like addresses, names, and company details, cleaning up messy input before it enters a database. 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.

04 · AUTH AND DATA

How DaData.ru connects.

Users add their DaData.ru 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 DaData.ru 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

DaData.ru and Arc0, answered.

Q01

Can I use DaData.ru with Claude, ChatGPT or Cursor?

Yes. Connect DaData.ru 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 DaData.ru actions you allow.

Q02

How do users connect DaData.ru?

Users add their DaData.ru 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 DaData.ru actions can my agent take?

63 in total: 27 read, 36 write and 0 destructive, such as “clean Name (FIO)”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in DaData.ru?

Yes. Allow read actions and deny writes in the DaData.ru policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call DaData.ru too?

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