description: Sets up Intlayer developer tooling - ESLint / oxlint rules, the Language Server (LSP), the VS Code extension, the MCP server, CI/CD automation and the Chrome extension. Use when the user asks to "lint hardcoded strings", "setup Go-to-Definition for dictionary keys", "install the Intlayer MCP", or "automate translations in CI".

# Intlayer Dev Tools

## Lint (ESLint / oxlint)

`eslint-plugin-intlayer` catches hardcoded strings, dynamic calls the Intlayer compiler cannot optimize, and unused dictionary content.

```bash

npm install --save-dev eslint-plugin-intlayer

```

Then spread `intlayer.configs.recommended` in your `eslint.config.mjs` (oxlint is also supported).

| Config | `no-raw-text` | `static-dictionary-key` | `no-dynamic-field-access` |

| --------------- | ------------- | ----------------------- | ------------------------- |

| `recommended` | warn | error | error |

| `strict` | error | error | error |

| `contract-only` | off | error | error |

## Language Server (LSP)

`@intlayer/lsp` (binary `intlayer-lsp`) brings Go-to-Definition from a `useIntlayer("key")` call to its `.content` file, Find References, hover previews, key autocompletion and diagnostics.

```bash

npm install --save-dev @intlayer/lsp

```

## VS Code Extension

Jump from a dictionary key to its content file, extract content from a component, and run build, fill, test, push and pull from the command palette.

## MCP Server

Gives AI assistants access to the Intlayer documentation and CLI.

```bash

npx intlayer init mcp

```

This writes the MCP configuration for your IDE (local `@intlayer/mcp` over stdio, or the hosted `https://mcp.intlayer.org`).

## CI/CD

Fill missing translations with AI on each change, and fail the build on missing ones:

```bash

npx intlayer fill --git-diff --mode complete

npx intlayer test

```

## Chrome Extension

Inspect the i18n setup of any website: framework, i18n library, locales, hreflang and SEO tags.
