Configuration Options

Environment Variables

• GLUESTACK_PATH: Path to local Gluestack UI installation.
• GITHUB_TOKEN: GitHub Personal Access Token for API access.
• LOG_LEVEL: Logging level (debug, info, warn, error).

Command Line Arguments

# Local mode
gluestack-mcp --gluestack-path /path/to/gluestack-ui --log-level debug

# GitHub mode 
gluestack-mcp --github-token ghp_xxxxxxxxxxxx --log-level debug

GitHub Mode (Fetch Latest Components)

Instead of requiring a local Gluestack UI installation, you can use GitHub mode to fetch the latest components directly from the official repository.

Setting up GitHub Mode

Step 1: Get a GitHub Personal Access Token

1. Go to GitHub Settings → Developer settings → Personal access tokens
2. Generate a new token (classic) with public_repo scope
3. Copy the token (starts with ghp_)

Step 2: Configure Your MCP Client

For Claude Desktop:

{
  "mcpServers": {
    "gluestack-ui": {
      "command": "npx",
      "args": ["gluestack-ui-mcp-server"],
      "env": {
        "GITHUB_TOKEN": "ghp_your_token_here"
      }
    }
  }
}

For Command Line:

export GITHUB_TOKEN="ghp_your_token_here"
gluestack-mcp

Benefits of GitHub Mode

• 🚀 Always Up-to-Date: Access the latest components directly from the main branch
• 📦 No Local Setup: No need to clone or maintain a local Gluestack UI repository
• 🔄 Automatic Updates: Components are fetched fresh from GitHub on each request
• 📊 Rate Limit Friendly: Authenticated requests get higher GitHub API limits (5000/hour vs 60/hour)
