Beaconstac for AI agents

Beaconstac is a QR code and proximity marketing platform, used by marketing teams to generate trackable QR codes and beacons and see how customers scan and engage with them. 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 Beaconstac connects.

Users add their Beaconstac 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 Beaconstac 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

Beaconstac and Arc0, answered.

Q01

Can I use Beaconstac with Claude, ChatGPT or Cursor?

Yes. Connect Beaconstac 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 Beaconstac actions you allow.

Q02

How do users connect Beaconstac?

Users add their Beaconstac 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 Beaconstac actions can my agent take?

21 in total: 8 read, 10 write and 3 destructive, such as “create Tag”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Beaconstac?

Yes. Actions like “delete Tag” 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 Beaconstac too?

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