What the Tolgee MCP server does

The Tolgee MCP server gives AI coding assistants access to translation-management actions in a Tolgee project. It is intended for developers who need to inspect and change localization data while working in an editor, without switching to a separate translation workflow for every change.

The server works with Tolgee projects and can handle common localization tasks: finding existing keys, adding translations, changing translations, managing languages, and starting machine-translation operations. The repository describes it as part of Tolgee, an open-source localization platform that can be used through Tolgee Cloud or a self-hosted deployment.

How it works

An MCP-compatible coding assistant communicates with Tolgee through the server. Requests from the assistant are translated into operations against the configured Tolgee project, allowing translation data to be queried or changed from the development environment.

The Tolgee MCP server complements Tolgee’s broader localization features. Machine translation can use services supported by the platform, including DeepL, Google Translate, AWS Translate, and Azure Translator, when those services are configured in Tolgee.

This workflow is useful when an agent needs to locate a string, create its localized content, revise an existing translation, or initiate translation automation as part of application work.

Tools and capabilities

The documented MCP capabilities include:

• Searching for translation keys.
• Creating translations.
• Updating translations.
• Managing project languages.
• Triggering machine translation.

Treat the repository’s MCP development documentation as the source for exact setup details and the current tool schema.

Setup and configuration

Use the MCP setup instructions in the repository’s DEVELOPMENT.md file.

Before using the server, a developer should have access to a Tolgee project in either the hosted Tolgee service or a self-hosted instance. The project must contain the languages and translation data the assistant is expected to manage. Any machine-translation operation also depends on the relevant provider configuration in Tolgee.

Limitations and notes

It also does not establish that every Tolgee platform feature—such as comments, activity logs, screenshots, or translation history—is exposed through MCP. Verify those details in the repository’s setup documentation before integrating the Tolgee MCP server into an automated workflow.

The platform itself supports in-context editing, translation memory, machine translation, and an AI translator, but those capabilities should not be assumed to be directly callable through MCP unless the current tool documentation confirms it.
