UILM MCP Server

MCP (Model Context Protocol) server for the SELISE Blocks UILM (UI Language Management) API. Provides translation key management tools for Claude Code, Cursor, and any MCP-compatible client.

Features

• Automatic Bearer token management (caches + auto-refreshes on 15-min expiry)
• Module name resolution (use "auth" instead of UUIDs)
• Batch key creation with automatic fallback
• 13 tools covering modules, languages, and translation keys

Quick Start

Option A: Interactive setup (recommended)

npx uilm-mcp-server --init

This walks you through entering credentials and writes the config directly to your Claude Code or Cursor settings.

Option B: Manual config

Add to your project's .mcp.json (Claude Code) or Cursor MCP settings:

{
  "mcpServers": {
    "uilm": {
      "command": "npx",
      "args": ["-y", "uilm-mcp-server"],
      "env": {
        "UILM_API_BASE_URL": "https://api.seliseblocks.com",
        "UILM_PROJECT_KEY": "your-project-key",
        "UILM_CLIENT_ID": "your-client-id",
        "UILM_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

No clone or build step required -- npx handles everything.

Option C: Using a .env file

Create a .env file in your project root (make sure it's in .gitignore):

UILM_API_BASE_URL=https://api.seliseblocks.com
UILM_PROJECT_KEY=your-project-key
UILM_CLIENT_ID=your-client-id
UILM_CLIENT_SECRET=your-client-secret

Then use a simpler MCP config without the env block:

{
  "mcpServers": {
    "uilm": {
      "command": "npx",
      "args": ["-y", "uilm-mcp-server"]
    }
  }
}

Getting Your Credentials

You need four values from the SELISE Blocks platform.

API Base URL

https://api.seliseblocks.com

Project Key

1. Log in to the SELISE Blocks Console
2. Select your project
3. Go to Settings (gear icon)
4. Copy the Project Key (starts with P)

Client ID and Client Secret

These are OAuth credentials used for machine-to-machine authentication:

1. In the SELISE Blocks Console, navigate to your project
2. Go to IAM > Clients (or Settings > API Clients, depending on your console version)
3. Click Create Client (or use an existing one)
4. Set the grant type to Client Credentials
5. Copy the Client ID (UUID format) and Client Secret

Note: If you don't see the Clients section, ask your project admin to create a client credential for you or grant you access to IAM settings.
