v0.1.0-alpha.9: MCP Configuration Fix

🐛 Bug Fix: MCP Server Configuration

What's Fixed

• Fixed critical MCP server startup failure in Claude Code
• Corrected @playwright/mcp invocation - removed invalid command-line arguments
• Updated all documentation and templates with correct configuration

Problem Solved

The MCP server was failing to start because we were passing command-line arguments to @playwright/mcp that it doesn't accept. This made the toolkit unusable with Claude Code.

Changes

• Simplified MCP configuration to just use @playwright/mcp without additional arguments
• Updated all code generators to produce correct configuration
• Fixed documentation examples

Installation

npm install -g claude-playwright@alpha

Verify Fix

After installation, run:

claude-playwright init

The generated .mcp.json should now contain:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["@playwright/mcp"]
    }
  }
}

Full Changelog

• .mcp.json - Fixed MCP configuration
• src/generators/mcp-setup.ts - Updated generator
• src/generators/init.ts - Updated init command
• README.md - Updated documentation
• docs/api.md - Updated API docs

v0.1.0-alpha.8 - Critical CLI Hotfix

🚨 Critical Hotfix Release

🐛 Fixed Critical Bug

The CLI was completely non-functional in versions alpha.5 through alpha.7

Users reported that commands like claude-playwright --version and claude-playwright init produced no output and silently failed.

✅ Resolution

• Removed require.main === module check that prevented execution
• Fixed parseAsync() to properly receive process.argv
• CLI now executes correctly when invoked via npm/npx

📦 Installation

# Update global installation
npm install -g claude-playwright@alpha

# Or in project
npm install claude-playwright@alpha --save-dev

🧪 Verification

After updating, verify the fix:

claude-playwright --version
# Should output: 0.1.0-alpha.8

claude-playwright --help
# Should display help information

📝 Technical Details

The issue was caused by the require.main === module check failing when the CLI was loaded through npm bin scripts. This is a common pattern that doesn't work reliably with how npm executes bin scripts.

🔄 Affected Versions

• ❌ v0.1.0-alpha.5 (broken)
• ❌ v0.1.0-alpha.6 (broken)
• ❌ v0.1.0-alpha.7 (broken)
• ✅ v0.1.0-alpha.8 (fixed)
