Localization as code — CLI and SDK for i1n
I1n Cli MCP server exists for a simple reason — assistants are far more useful when they can act on I1n Cli directly instead of describing what you should do. Localization as code — CLI and SDK for i1n.
Localization as code. Push your translation keys, AI translates to 182 languages, pull type-safe TypeScript definitions. Built for developers, AI agents, and product teams.
The server ships on npm as i1n, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once I1n Cli is connected, these are the calls the assistant has available:
Pluralization — Define plural variants with _zero, _one, _other suffixes:Interpolation — Three syntaxes supported universally: {var}, {{var}}, %{var}You will need one environment variable: STORAGE_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. 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. I1n Cli's toolset — Pluralization, Interpolation — is a fair guide to whether it matches your workflow. It is maintained by pakvothe; worth a glance at recent repository activity before you build anything load-bearing on it.
