- **PHP**: Syntax errors, static analysis (PHPStan), code style (PHP_CodeSniffer)
- **TypeScript**: Compilation errors, type checking, build issues
- **Python**: Syntax errors, static analysis (when tools available)
- **Go**: Compilation errors, vet analysis (when tools available)
- **Rust**: Compilation errors, clippy analysis (when tools available)
### ⚡ **Real-time Error Detection**
- **Console errors**: Real-time capture from running applications
- **Build errors**: TypeScript/JavaScript compilation issues
- **Runtime errors**: Exception tracking and categorization
- **Linter errors**: Code quality and style issues
- **Test errors**: Test failure detection and analysis
### 🧠 **AI-Enhanced Analysis**
- **Error categorization**: Automatic classification (syntax, type, runtime, security)
- **Severity assessment**: High/Medium/Low impact analysis
- **Fix suggestions**: Actionable recommendations
- **Root cause analysis**: Deep error investigation
## 📖 Understanding MCP Transport
The Error Debugging MCP Server uses **stdio transport**, which means:
- ✅ Communication happens through stdin/stdout (not network ports)
- ✅ The IDE launches the server as a child process
- ✅ No network configuration or firewall setup required
- ✅ Secure local communication only
- ✅ Cross-platform compatibility (Windows, macOS, Linux)
## 📋 Prerequisites
1. **Server built and ready**: ✅ Confirmed working
2. **Node.js**: v22.14.0+ ✅ Required for server execution
3. **MCP-compatible IDE**: Choose from supported options below
4. **Server executable**: `/path/to/error-debugging-mcp-server/dist/index.js`
5. **Language tools** (optional for enhanced detection):
- **JavaScript**: Node.js (included), ESLint (optional)
- **PHP**: PHP CLI, Composer, PHPStan (optional), PHP_CodeSniffer (optional)
- **TypeScript**: TypeScript compiler (`tsc`)
- **Python**: Python interpreter, pylint/flake8 (optional)
- **Go**: Go compiler (`go`)
- **Rust**: Rust compiler (`rustc`), Cargo, Clippy (optional)
## ⚠️ Important Notes
- **No port configuration needed**: MCP servers using stdio transport don't require port/host settings
- **IDE must support MCP**: Ensure your IDE has MCP client capabilities
- **Process-based communication**: The IDE will launch the server as a subprocess
- **Language tool detection**: Server automatically detects available language tools and enables appropriate handlers
- **Graceful degradation**: Server works without optional language tools, providing basic error detection
