Lokalise for AI agents

Lokalise is a localization management platform that helps teams manage translation keys, files, and contributors across multilingual products and marketing content. 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.

01 · USE CASES

What agents do in Lokalise.

01

Add a new translation key

Create a new key with source text so translators can add it to their language files.

02

Check a project's translations

Pull existing translations for a key across languages to check for consistency, read-only.

03

Approve before deleting keys

Require approval before deleting translation keys, since it removes them from every language.

02 · ACTIONS

10 Lokalise actions, graded by risk.

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

  3. 03Any agent can actYour agent calls Lokalise through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

await arc0.policies.set('lokalise', {
  read: 'allow',
  write: 'ask',        // create_keys

04 · AUTH AND DATA

How Lokalise connects.

Users add their Lokalise 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 Lokalise 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

Lokalise and Arc0, answered.

Q01

Can I use Lokalise with Claude, ChatGPT or Cursor?

Yes. Connect Lokalise 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 Lokalise actions you allow.

Q02

How do users connect Lokalise?

Users add their Lokalise 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 Lokalise actions can my agent take?

10 in total: 6 read, 3 write and 1 destructive, such as “create Keys”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Lokalise?

Yes. Actions like “delete Keys” 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 Lokalise too?

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