# Claude TypeScript MCP Servers (For Software Developers)

A comprehensive collection of Model Context Protocol (MCP) servers that
transform Claude Desktop into a powerful development assistant. This project
leverages your flat-rate Claude Pro/Max subscription to provide capabilities
similar to Cline, but without the per-token API costs.

## 💡 Usage Examples

### Development Workflow

```
You: "Create a new React component for user authentication"
Claude: *Uses filesystem to create component file, npm to install dependencies*

You: "Find examples of OAuth implementation on GitHub"
Claude: *Uses GitHub search and fetch to find and analyze implementations*

You: "Test the login form on our staging site"
Claude: *Uses Puppeteer to navigate, fill forms, and verify functionality*
```

### Research and Analysis

```
You: "What are the latest best practices for Next.js 14 App Router?"
Claude: *Uses Sonar for comprehensive research with citations*

You: "Compare our package.json with similar projects"
Claude: *Uses GitHub to find similar projects, filesystem to read local files*
```

### Automation

```
You: "Extract all product prices from this e-commerce site"
Claude: *Uses Puppeteer to navigate pages, extract data, and compile results*

You: "Monitor our GitHub issues and create a summary"
Claude: *Uses GitHub API to fetch issues, analyze patterns, generate report*
```

## 🔒 Security Considerations

- **File System**: Restricted to specified directories only
- **Shell**: Commands must be in the allowlist
- **Credentials**: Store API keys securely, use environment variables
- **GitHub**: Use minimal token permissions
- **Fetch**: Respects robots.txt by default

```

## 🚧 Development

To add new functionality:

1. Create a new TypeScript file in `src/`
2. Implement the MCP server using `@modelcontextprotocol/sdk`
3. Add tool definitions with clear descriptions
4. Include proper error handling and validation
5. Update the configuration file

### Testing Your Changes

```bash
# Run a specific MCP server directly
bun run src/your-new-server.ts

# Test with Claude Desktop
# Update your config and restart Claude
```

### Type Checking

This project uses TypeScript for type safety. Several type checking commands are
available:

```bash
# Standard type check (all strict checks enabled)
bun run type-check

# Type check with file watching for development
bun run type-check:watch

# Type check without unused variable warnings (good for development)
bun run check:loose

# Strict type check (same as type-check)
bun run check:strict
```

#### Current Type Issues

The project is functional but has some type issues that are being addressed:

- Some Puppeteer APIs need proper type imports
- A few cases of potential undefined values need guards
- Unused variables in some files (can be ignored during development)

These don't affect runtime functionality but will be cleaned up over time.

### Code Formatting

This project uses Prettier for consistent code formatting. The following
commands are available:

```bash
# Format all files
bun run format

# Check formatting without making changes
bun run format:check

# Format only source files (src directory)
bun run format:src

# Check formatting of source files only
bun run format:check:src

# Run both formatting check and type check
bun run lint

# Fix formatting and run type check
bun run lint:fix
```

#### Prettier Configuration

The project uses the following Prettier settings (`.prettierrc`):

- **Print Width**: 100 characters (80 for JSON/Markdown)
- **Tab Width**: 2 spaces
- **Semicolons**: Always
- **Quotes**: Double quotes
- **Trailing Commas**: All (ES5+)
- **Arrow Parens**: Always include parentheses

#### Formatting on Save

For the best development experience, configure your editor to format on save:

**VS Code**: Add to `.vscode/settings.json`:

```json
{
  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode"
}
```

**Other Editors**: Check your editor's documentation for Prettier integration.
