Tolgee: MCP server, setup and security

What Tolgee does

According to its repository: “Your app's translations in Tolgee: search keys, create translations, trigger machine translation”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Tolgee is listed under Web search and extraction, a category of 159 servers in the directory, where it ranks #4 by stars.

Topics declared by the repository: localization, localization-tool, internationalization, i18n, i18next, l10n.

Installing and connecting Tolgee

Distribution modes declared in the official MCP registry:

• remote server (streamable-http): you connect to it by URL, with nothing to install locally

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for Tolgee:

• No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on October 13, 2020, the tolgee/tolgee-platform repository has 4,139 stars and 377 forks, with 177 open issues. It has more stars than 97% of the servers in the directory. It received changes this month. Version published in the registry: 1.0.0 (April 9, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
