Backendless for AI agents

Backendless is a backend-as-a-service platform giving mobile and web apps user authentication, a data store, file storage, and messaging without teams standing up their own servers. 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.

EVERY BACKENDLESS CALL, ON THE RECORD

01 · USE CASES

What agents do in Backendless.

Look up a user record

Find a user by ID and check their account details before a support agent resets access.

Manage files in storage

Upload, move, or copy a file between directories in Backendless file storage as part of a content update.

Delete a stale user account

Delete a user account only after confirming it's inactive and the request is approved, since removal can't be undone.

03 · HOW IT WORKS

Backendless in three steps.

01Your users connect BackendlessThey add their Backendless api key on Arc0 Connect, under your brand. It goes straight into the vault.
02You set the rulesReads run, writes like “create Backendless Hive” can wait for the user, and “delete File” can be denied outright.
03Any agent can actYour agent calls Backendless through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

POLICY.TS

await arc0.policies.set('backendless', {
  read: 'allow',
  write: 'ask',        // create_hive
  destructive: 'deny',  // delete_file
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \
    https://mcp.arc0.ai/u/u_8f2

04 · AUTH AND DATA

How Backendless connects.

Users add their Backendless 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 Backendless connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

AUTH: API key
CREDENTIALS: Per-tenant encrypted vault
MODEL SEES: Results only, never credentials
AUDIT LOG: Every call, on every plan

07 · FAQ

Backendless and Arc0, answered.

Q01

Can I use Backendless with Claude, ChatGPT or Cursor?

Yes. Connect Backendless 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 Backendless actions you allow.

Q02

How do users connect Backendless?

Users add their Backendless 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 Backendless actions can my agent take?

30 in total: 6 read, 18 write and 6 destructive, such as “create Backendless Hive”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Backendless?

Yes. Actions like “delete File” 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 Backendless too?

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