A comprehensive Model Context Protocol (MCP) server for i18next translation management, health checking, and automated translation workflows
I18next MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A comprehensive Model Context Protocol (MCP) server for i18next translation management, health checking, and automated translation workflows.
A Model Context Protocol (MCP) server that provides translation management capabilities for i18next projects, enabling AI assistants like Cursor to directly interact with translation files.
Installation goes through your MCP client rather than a global install: point it at i18next-mcp-server on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once I18next is connected, these are the calls the assistant has available:
Analysis — The Analysis tool exposed by this serverYou will need 4 environment variables: I18N_PROJECT_ROOT, I18N_LOCALES_PATH, I18N_DEFAULT_LANGUAGE, I18N_SUPPORTED_LANGUAGES. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. I18next's toolset — Analysis — is a fair guide to whether it matches your workflow. It is maintained by gtrias; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against I18next's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
