## 🔧 Configuration & Requirements
### Multi-Backend Configuration
The system is pre-configured with 4 backends (expandable via [EXTENDING.md](EXTENDING.md)):
#### **Local Backend Endpoint**
- **URL**: `http://localhost:1234/v1` (configure for your local model server)
- **Example Setup**: LM Studio, Ollama, vLLM, or custom OpenAI-compatible endpoint
- **Requirements**:
- Local model server running (LM Studio/Ollama/vLLM/etc.)
- Server bound to `0.0.0.0:1234` (not `127.0.0.1` for WSL2 compatibility)
- Firewall allowing connections if running on separate machine
#### **Cloud Backend Endpoints**
- **Example Configuration**: NVIDIA API, OpenAI, Anthropic, Azure OpenAI, AWS Bedrock, etc.
- **API Keys**: Required (set via environment variables for each provider)
- **Endpoint URLs**: Configure based on your chosen providers
- **Models**: Any models available from your providers (see [EXTENDING.md](EXTENDING.md) for integration)
### Cross-Platform Support
#### **Windows (WSL2)**
```bash
# WSL2 IP for local model (if running on Windows host)
export LOCAL_MODEL_ENDPOINT="http://172.23.16.1:1234/v1"
```
#### **Linux**
```bash
# Direct localhost for Linux
export LOCAL_MODEL_ENDPOINT="http://127.0.0.1:1234/v1"
```
#### **macOS**
```bash
# Standard localhost for macOS
export LOCAL_MODEL_ENDPOINT="http://localhost:1234/v1"
```
### Environment Variables
```bash
# Example using NVIDIA API (configure for your chosen providers)
export CLOUD_API_KEY_1="your-cloud-provider-key"
export CLOUD_API_KEY_2="your-cloud-provider-key"
export CLOUD_API_KEY_3="your-cloud-provider-key"
# Local model endpoint
export LOCAL_MODEL_ENDPOINT="http://localhost:1234/v1"
# Optional: Enable TDD mode for testing
export TDD_MODE="true"
# MCP-Compliant Logging Configuration
# Options: silent, error, warn, info, debug
# Production: Use 'error' or 'warn' for minimal logging
# Development: Use 'info' or 'debug' for full diagnostics
export MCP_LOG_LEVEL="info"
```
### MCP-Compliant Logging
**CRITICAL**: This server is fully MCP protocol compliant and prevents the "stdout contamination" issue that breaks Claude Desktop.
#### Understanding MCP Logging Requirements
The Model Context Protocol (MCP) has strict requirements for stdio-based servers:
- **stdout** → ONLY JSON-RPC messages (protocol communication)
- **stderr** → Logging, diagnostics, debug output (captured by Claude Desktop)
**Common Issue**: Using `console.log()` writes to stdout and breaks MCP communication with errors like:
```
SyntaxError: Unexpected token 'C', "Conversati"... is not valid JSON
```
#### Our Solution: MCP-Compliant Logger
All logging in Smart AI Bridge uses `console.error()` (stderr) to maintain protocol compliance:
```javascript
// ✅ CORRECT - MCP compliant (stderr)
import { logger } from './mcp-logger.js';
logger.info('Server started');
logger.debug('Routing decision:', backend);
logger.error('Fatal error:', error);
// ❌ WRONG - Breaks MCP protocol (stdout)
console.log('Message'); // Will cause JSON parse errors in Claude Desktop
```
#### Log Levels
Control logging verbosity via `MCP_LOG_LEVEL` environment variable:
| Level | Description | Use Case |
|-------|-------------|----------|
| `silent` | No logging output | Production with external monitoring |
| `error` | Errors only | Minimal production logging |
| `warn` | Warnings + errors | Recommended for production |
| `info` | Info + warnings + errors | **Default** - Development/staging |
| `debug` | All messages including debug | Verbose debugging |
#### Configuration Examples
**Production (minimal logging)**:
```bash
export MCP_LOG_LEVEL="warn"
# or in .env file:
MCP_LOG_LEVEL=warn
```
**Development (full diagnostics)**:
```bash
export MCP_LOG_LEVEL="debug"
# Shows detailed routing decisions, backend health checks, etc.
```
**Silent mode (external logging)**:
```bash
export MCP_LOG_LEVEL="silent"
# All logging suppressed, useful when piping stderr to monitoring tools
```
#### Claude Desktop Log Files
Claude Desktop automatically captures all stderr output to log files:
- **macOS**: `~/Library/Logs/Claude/mcp-server-smart-ai-bridge.log`
- **Windows**: `%APPDATA%\Claude\Logs\mcp-server-smart-ai-bridge.log`
- **Linux**: `~/.config/Claude/logs/mcp-server-smart-ai-bridge.log`
#### Troubleshooting MCP Protocol Issues
If you see JSON parse errors in Claude Desktop:
1. **Check for stdout contamination**:
```bash
grep -r "console\.log" --include="*.js" --exclude-dir=node_modules
```
2. **Verify all logging uses stderr**:
- All logs should use `logger.info()`, `logger.debug()`, etc.
- Or `console.error()` directly (not `console.log()`)
3. **Test with silent mode**:
```bash
MCP_LOG_LEVEL=silent npm start
# Should produce NO stderr output
```
4. **View captured logs**:
```bash
# macOS/Linux
tail -f ~/Library/Logs/Claude/mcp-server-smart-ai-bridge.log
```
## 🎮 Optimization Pipeline Workflow
**Discovery → Implementation → Validation** - The proven pattern for high-quality results:

## 📁 File Access Architecture
### Smart File Size Routing
The system automatically routes files based on size for optimal performance:
```javascript
// Routing Logic
if (fileSize > 100KB) → Local Backend (unlimited tokens)
else if (fileSize > 10KB) → Intelligent routing based on content
else if (fileSize < 10KB) → Smart endpoint selection
```
### File Processing Strategies
#### **Instant Processing** (<1KB files)
- **Strategy**: Direct memory read with 1-second timeout
- **Performance**: <1ms processing time
- **Use Cases**: Configuration files, small scripts, JSON configs
#### **Fast Processing** (1KB-10KB files)
- **Strategy**: Standard file read with 3-second timeout
- **Performance**: <100ms processing time
- **Use Cases**: Component files, utility functions, small modules
#### **Standard Processing** (10KB-100KB files)
- **Strategy**: Buffered read with 5-second timeout
- **Performance**: <500ms processing time
- **Use Cases**: Large components, documentation, medium codebases
#### **Chunked Processing** (>100KB files)
- **Strategy**: Streaming with 50MB memory limit
- **Performance**: Chunked with progress tracking
- **Use Cases**: Large log files, extensive documentation, complete codebases
### Cross-Platform Path Handling
#### **Windows Support**
```javascript
// Automatic path normalization
"C:\Users\project\file.js" → "C:/Users/project/file.js"
// WSL path translation
"/mnt/c/Users/project" → "C:/Users/project"
```
#### **Security Validation**
- **Path Traversal Protection**: Blocks `../` and absolute path escapes
- **Malicious Content Detection**: Scans for suspicious patterns
- **File Size Limits**: Prevents memory exhaustion attacks
- **Permission Validation**: Ensures safe file access
### Batch Processing Optimization
#### **Concurrent Processing**
- **Batch Size**: Up to 5 files concurrently
- **Memory Management**: 50MB total limit per batch
- **Strategy Selection**: Based on total size and file count
- **Performance Monitoring**: Real-time processing metrics
#### **Intelligent Batching**
```javascript
if (totalSize > 100KB) → "local_endpoint_chunked"
else if (fileCount > 10) → "concurrent_limited"
else → "standard_parallel"
```
## 🐛 Troubleshooting & Diagnostics
### Multi-Backend Issues
#### **Local Backend Connection**
```bash
# Test local endpoint (adjust IP for your setup)
curl http://localhost:1234/v1/models
# Check local model server status
1. Verify local model server is running (LM Studio/Ollama/vLLM/etc.)
2. Confirm model is loaded and ready
3. Ensure server binding is 0.0.0.0:1234 (not 127.0.0.1 for WSL2)
4. Check firewall rules if running on separate machine
```
#### **Cloud Backend Issues**
```bash
# Test cloud API access (example using NVIDIA API)
curl -H "Authorization: Bearer $CLOUD_API_KEY_1" \
https://integrate.api.nvidia.com/v1/models
# Common fixes:
1. Verify API keys are set correctly for your providers
2. Check API key permissions and rate limits
3. Ensure internet connectivity
4. Validate model names and endpoint URLs in configuration
```
### File Access Issues
#### **Permission Problems**
```javascript
// Use diagnose_file_access tool (when implemented)
@diagnose_file_access(filePath="/path/to/problematic/file")
// Manual checks:
1. Verify file exists and is readable
2. Check path normalization (Windows vs Unix)
3. Validate security constraints
4. Test with smaller file sizes first
```
#### **Cross-Platform Path Issues**
```bash
# Windows (WSL2)
- Use forward slashes: "/mnt/c/project/file.js"
- Avoid Windows drive letters in WSL context
# Linux/macOS
- Standard Unix paths work normally
- Ensure proper permissions on file system
```
### MCP Server Issues
#### **Server Startup Problems**
```bash
# Diagnostics
1. Check Node.js version: node --version (>=18 required)
2. Install dependencies: npm install
3. Test server: npm test
4. Check server logs: tail -f ~/.claude-code/logs/server.log
```
#### **Tool Registration Issues**
```bash
# Verify MCP tools are registered
@check_deepseek_status()
# If tools missing:
1. Restart Claude Code completely
2. Check configuration file syntax
3. Verify file paths in config
4. Test with minimal configuration first
```
### Performance Optimization
#### **Slow File Processing**
- **Large Files**: Automatically routed to Local Backend for unlimited processing
- **Batch Operations**: Use concurrent processing for multiple small files
- **Memory Issues**: Files >50MB trigger streaming mode with memory protection
#### **Routing Performance**
- **Pattern Matching**: Smart routing uses optimized regex patterns
- **Endpoint Health**: Unhealthy endpoints trigger automatic fallback
- **Usage Statistics**: Monitor routing decisions for optimization
