L2s for AI agents

L2S is a URL shortener built for teams, offering branded short links, click analytics, and QR codes for marketers running multi-channel campaigns. 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.

  2. 02You set the rulesReads run, and writes like “list Shortened URLs” can wait for the user to approve.
  3. 03Any agent can actYour agent calls L2s through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

04 · AUTH AND DATA

How L2s connects.

Users add their L2s 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 L2s 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

L2s and Arc0, answered.

Q01

Can I use L2s with Claude, ChatGPT or Cursor?

Yes. Connect L2s 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 L2s actions you allow.

Q02

How do users connect L2s?

Users add their L2s 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 L2s actions can my agent take?

4 in total: 1 read, 3 write and 0 destructive, such as “list Shortened URLs”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in L2s?

Yes. Allow read actions and deny writes in the L2s policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call L2s too?

Yes. The same L2s connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
