`๐ MCP Client Configuration
To use this MCP server with Claude Desktop or other MCP clients, you need to configure the client settings.
$3
1. Locate the Claude Desktop config file:
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json2. 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
`$3
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"]
}
`$3
Ensure all required environment variables are set:
`bash
Copy environment template
cp .env.example .envEdit 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
- TRIVY_CACHE_DIR๐ Configuration
$3
Key environment variables (see
.env.example for complete list):`bash
Server Configuration
NODE_ENV=production
MCP_PORT=3000
SECURITY_STRICT_MODE=trueTool Configuration
SONARQUBE_TOKEN=your-token
ZAP_API_KEY=your-key
OSV_SCANNER_PATH=osv-scanner
TRIVY_PATH=trivy
TRIVY_CACHE_DIR=/tmp/trivy-cache
`$3
Edit
src/config/security-rules.yml to customize:- Vulnerability thresholds
- Quality gates
- Policy enforcement
- Tool configurations
$3
Edit
src/config/tool-configs.json for:- Tool-specific settings
- Scan policies
- Integration parameters

$3
#### 1. Security Tools Installation Failure
`bash
Issue: pip3 permission error
Solution:
pip3 install --user semgrep banditOr 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 buildPermanent 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
