Codemagic for AI agents

Codemagic is a CI/CD platform built for mobile app development, automating builds and releases for iOS and Android projects at scale. 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 Codemagic.

01

Start a new build for an application once code changes are ready to test.

02

Check recent builds

Check the status of recent builds before deciding whether a release is ready to ship.

03

Confirm before removing a team member

02 · ACTIONS

22 Codemagic actions, graded by risk.

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

03 · HOW IT WORKS

Codemagic in three steps.

  1. 01Your users connect CodemagicThey add their Codemagic api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “update Variable in Group” can wait for the user, and “delete Specific Cache” can be denied outright.
  3. 03Any agent can actYour agent calls Codemagic 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('codemagic', {
  read: 'allow',
  write: 'ask',        // update_variable
  destructive: 'deny',  // delete_specific_cache
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How Codemagic connects.

Users add their Codemagic 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 Codemagic 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

Codemagic and Arc0, answered.

Q01

Can I use Codemagic with Claude, ChatGPT or Cursor?

Yes. Connect Codemagic 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 Codemagic actions you allow.

Q02

How do users connect Codemagic?

Users add their Codemagic 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 Codemagic actions can my agent take?

22 in total: 9 read, 10 write and 3 destructive, such as “update Variable in Group”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Codemagic?

Yes. Actions like “delete Specific Cache” 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 Codemagic too?

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