Set Environment Variables:
- serverUrl: http://localhost:3000
- sessionId: (automatically set after initialization)
Run Tests:
- Health check and server status
- MCP session initialization
- All 26 tools (13 market analysis + 13 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

Technology Stack

Language: TypeScript 5.x
Protocol: MCP 2025-03-26
Framework: Express.js 4.x
Validation: Zod schemas
Testing: Vitest + Postman
Cache: NodeCache (Redis optional)
Logging: Winston

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
