Dropbox Sign for AI agents

Dropbox Sign, formerly HelloSign, provides e-signature and document workflow tools for collecting legally binding signatures online, used by sales and HR teams closing agreements quickly. 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 Dropbox Sign.

01

Send a signature request

Create an embedded signature request from a template once the sender confirms the signer list.

02

Check a signature request's status

Get a signature request to see whether all parties have signed a contract yet.

03

Confirm before canceling a request

Require sign-off before canceling a signature request, since it stops an agreement already sent to a signer.

02 · ACTIONS

56 Dropbox Sign actions, graded by risk.

Every Dropbox Sign action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

07 · FAQ

Dropbox Sign and Arc0, answered.

Q01

Can I use Dropbox Sign with Claude, ChatGPT or Cursor?

Yes. Connect Dropbox Sign 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 Dropbox Sign actions you allow.

Q02

How do users connect Dropbox Sign?

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

Q03

Which Dropbox Sign actions can my agent take?

56 in total: 26 read, 25 write and 5 destructive, such as “create Report”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Dropbox Sign?

Yes. Actions like “delete Fax” 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 Dropbox Sign too?

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