This server has a remotely hosted endpoint. Open its connector listing for connection details, authentication requirements, and setup instructions:
Manage your app's translations from Claude, ChatGPT, Cursor, VS Code and any other AI app that speaks the Model Context Protocol.
LiteI18n stores your app's translation keys, lets you draft and review translations, and ships them to your app over the air (OTA), with no app store release. This hosted MCP server lets an AI agent do that work for you: find keys, add new copy, draft translations, publish them and ship a release.
https://mcp.litei18n.com/mcpHosted. Nothing to install, no package, no token to copy.
Browser sign-in (OAuth 2.1). Your AI app opens LiteI18n, you sign in, pick the workspace, projects and access level, and approve.
You stay in control. Every connection is listed under Connect AI in your workspace, where you can disconnect it at any time. Access is set per project.
Safe by default. Writes are drafts until you publish them, and every tool tells your AI app whether it reads, changes or publishes, so the app can ask you first.

"Add a key for the new checkout button and translate it into every language in the project."
"Which keys in the onboarding screens are missing a German translation? Draft them."

Tool | What it does | Kind | Permission |
| List the projects this connection can reach, with languages, key count and permissions | Read | — |
| Find, search or fetch keys with their live translations and drafts | Read |
|
| Create up to 100 keys, optionally with first translations (saved as drafts) | Write |
|
| Save draft translations for up to 500 key and language pairs | Write |
|
| Delete a key. A published key is removed at the next publish and can be restored until then | Destructive |
|
| Undo a pending key deletion, before publishing | Write |
|
| Publish drafts as live translations (optionally one language) | Destructive |
|
| List the project's OTA releases | Read |
|
| Ship the latest published translations to your apps over the air | Destructive |
|
Every tool declares a title and the standard MCP safety hints (readOnlyHint, destructiveHint,
idempotentHint, openWorldHint), so your AI app can ask before it publishes or deletes. Results
are structured data matching each tool's output schema. Text written by project members (key
names, translations, drafts) is marked as content, never as instructions.
When you approve a connection you choose, for each project, what the AI app may do:
Scope | Allows |
| Find and read keys |
| Create, delete and restore keys |
| Read translations and drafts |
| Save draft translations |
| Publish drafts |
| List releases |
| Create OTA releases |
Presets: Read only (all reads), Read and write (all reads, key and translation writes, publishing), Full access (everything, including releases).
skills/litei18n is an Agent Skill that
teaches your agent the LiteI18n workflow: look before writing, drafts versus publishing, when to
ask first, and how to load OTA translations in your app with a safe fallback. It works with the
MCP server above; it is optional but makes agents more careful and more accurate.
Claude Code (plugin: MCP server and skill together)
/plugin marketplace add Aevum-Technology/litei18n-mcp
/plugin install litei18n@litei18nAny agent that supports skills (Claude Code, Codex, Cursor, OpenCode and others)
npx skills add Aevum-Technology/litei18n-mcp --skill litei18nClaude.ai and the Claude desktop app: download this repository as a ZIP, then upload the
skills/litei18n folder (zipped) under Customize → Skills.
Manually: copy skills/litei18n into your agent's skills folder, for example
~/.claude/skills/litei18n or .agents/skills/litei18n.
Scripts and CI jobs can call the same link with a LiteI18n API token instead of signing in. Create
one under API Tokens in your workspace and send it as Authorization: Bearer litei18n_…. Keep
it in your CI's secret store, never in code or chat.
A LiteI18n account. MCP access is included on every plan, Free too.
The workspace owner or admin role to approve a connection.
Creating OTA releases needs the Starter plan or above.
You see | What to do |
Asked to sign in again | The connection was disconnected or expired. Sign in from your AI app again. |
"No access to this project" | The project was not selected when you approved. Reconnect and tick it. |
"Permission denied" | The connection lacks that permission for the project. Reconnect with a higher access level. |
"Your plan does not allow this action" | Creating OTA releases needs the Starter plan or above. Upgrade under Billing. |
"This workspace has been suspended" | Contact support. Access returns once the suspension is lifted. |
Too many requests | Each connection may make 60 requests a minute. Wait a moment and try again. |
