## 🔌 MCP Client Configuration

To use this MCP server with Claude Desktop or other MCP clients, you need to configure the client settings.

### Claude Desktop Configuration

1. **Locate the Claude Desktop config file:**
   - **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
   - **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

2. **Add the DevSecOps MCP server configuration:**
   ```json
   {
     "mcpServers": {
       "devsecops": {
         "command": "node",
         "args": ["dist/src/mcp/server.js"],
         "cwd": "/path/to/DevSecOps-MCP",
         "env": {
           "NODE_ENV": "production",
           "MCP_PORT": "3000",
           "LOG_LEVEL": "info",
           "SECURITY_STRICT_MODE": "true"
         }
       }
     }
   }
   ```

3. **Alternative: Use the provided configuration file:**
   ```bash
   # Copy the provided configuration
   cp .mcprc.json ~/Library/Application\ Support/Claude/claude_desktop_config.json
   
   # Edit the cwd path to match your installation
   ```

### Other MCP Clients

For other MCP clients, use the server configuration from `mcp-server.json`:

```json
{
  "name": "devsecops-mcp-server",
  "command": "node dist/src/mcp/server.js",
  "args": [],
  "capabilities": ["tools"]
}
```

### Environment Setup

Ensure all required environment variables are set:

```bash
# Copy environment template
cp .env.example .env

# Edit with your configuration
nano .env
```

**Required for basic functionality:**
- `SONARQUBE_URL` (if using SonarQube)
- `ZAP_URL` (if using OWASP ZAP)

**Optional but recommended:**
- `OSV_SCANNER_PATH`
- `TRIVY_PATH`

## 🔧 Troubleshooting (based on real experience)

### Common Issues

#### 1. Security Tools Installation Failure
```bash
# Issue: pip3 permission error
# Solution:
pip3 install --user semgrep bandit

# Or with system permissions
sudo pip3 install semgrep bandit
```

#### 2. TypeScript Compilation Errors  
```bash
# Issue: Strict type checking errors
# Temporary solution: Skip compilation and run with JavaScript
node test-all-security.js  # Test without TypeScript build

# Permanent solution: Fix tsconfig.json configuration
```

#### 3. Docker Permission Issues
```bash
# Issue: No Docker execution permissions
# Solution:
sudo usermod -aG docker $USER
newgrp docker
```

#### 4. Port Conflicts
```bash
# Issue: Ports 3000, 3001 already in use
# Solution:
export MCP_PORT=3002
node test-vulnerable-server.js  # Use different port
```

#### 5. Vulnerable Dependencies Installation Failure
```bash
# Issue: node-sass compilation error
# Solution: Install excluding problematic packages
cd test-vulnerable-dependencies
npm install --ignore-engines
```
