Eversign for AI agents

Eversign, now Xodo Sign, is a cloud digital signature platform for signing, sending, and managing documents online, used by teams that need a lightweight e-signature workflow. 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 Eversign connects.

Users add their Eversign 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 Eversign 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

Eversign and Arc0, answered.

Q01

Can I use Eversign with Claude, ChatGPT or Cursor?

Yes. Connect Eversign 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 Eversign actions you allow.

Q02

How do users connect Eversign?

Users add their Eversign 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 Eversign actions can my agent take?

10 in total: 5 read, 4 write and 1 destructive, such as “create Document”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Eversign?

Yes. Actions like “delete Document or Template” 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 Eversign too?

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