   • sessionId: (automatically set after initialization)
3. Run Tests:
   • Health check and server status
   • MCP session initialization
   • All 28 tools (11 market analysis + 17 data access)
   • Resource access endpoints
   • Session management and cleanup

Newman CLI Testing Automate Postman tests from command line:

# Install Newman
npm install -g newman

# Run backend API tests
newman run examples/TAM-MCP-Server-Postman-Collection.json \
  -e tests/postman/environments/TAM-MCP-Server-Environment.postman_environment.json \
  --reporters cli,json

# Or use npm script
npm run test:postman

Test Coverage

• Unit Level: Individual tool functionality and business logic
• Integration Level: MCP protocol compliance and server behavior
• System Level: Complete workflows through real transports
• API Level: REST endpoints and session management

Troubleshooting

Common Issues

Services showing as disabled despite API keys

• Ensure .env file is in project root
• Check API key variable names match exactly
• Restart server after adding keys
• Verify startup logs show service initialization

MCP Inspector connection issues

• Use: npx @modelcontextprotocol/inspector node dist/stdio-simple.js
• Ensure no console.log statements contaminate stdout
• Check Winston logger uses stderr for output

Build errors

• Run npm install to update dependencies
• Check Node.js version (20.x recommended)
• Clear build cache: rm -rf dist && npm run build

No data returned from tools

• Check service status in startup logs
• Verify API quotas not exceeded
• Test with generic_data_query tool
• Check network connectivity
