🔌 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.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
`

$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 .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
- TRIVY_CACHE_DIR

🔧 Troubleshooting (based on real experience)

$3

#### 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
