Postman MCP Server

Implementation Plan for Sample Express Server with Postman Tests: Dependencies Required (devDependencies): { "devDependencies": { "@types/express": "^4.17.x", "@types/node": "^20.x.x", "express": "^4.18.x", "typescript": "^5.x.x" } } Example Directory Structure: example/ ├── src/ │ └── server.ts # Express server implementation ├── postman/ │ ├── collection.json # Postman collection file │ └── environment.json # Postman environment file ├── package.json # Project dependencies └── tsconfig.json # TypeScript configuration Server Implementation Plan (server.ts): Create an Express server with two endpoints: GET /api/items - Returns a list of sample items POST /api/items - Accepts a new item and returns the created item Server will run on port 3000 Include proper TypeScript types for request/response objects Implement basic error handling Add request logging middleware Postman Environment (environment.json): { "name": "Sample API Environment", "values": [ { "key": "baseUrl", "value": "http://localhost:3000", "type": "default", "enabled": true } ] } Postman Collection Plan (collection.json): Collection Name: "Sample API Tests" Two request folders: GET Requests Test endpoint: GET {{baseUrl}}/api/items Tests to verify: Status code is 200 Response is an array Response time is acceptable POST Requests Test endpoint: POST {{baseUrl}}/api/items Request body: JSON object with item details Tests to verify: Status code is 201 Response contains created item Response matches request schema Additional Considerations: Error Handling: Implement proper HTTP status codes Return meaningful error messages Add request validation TypeScript Types: Define interfaces for request/response objects Use proper type annotations Ensure strict type checking Testing Strategy: Collection will include pre-request scripts Environment variables for configuration Test assertions for each endpoint Response schema validation Documentation: Add API documentation in collection Include example requests/responses Document environment setup This implementation plan provides a structured approach to creating a sample Express server with Postman tests while maintaining TypeScript best practices and proper testing coverage.
