Use the run-collection tool 2. Analyze the test results 3. Provide a human-friendly summary of the execution ## Development ### Project Structure ``` src/ ├── index.ts # Entry point ├── server/ │ ├── server.ts # MCP Server implementation │ └── types.ts # Type definitions └── newman/ └── runner.ts # Newman runner implementation test/ ├── server.test.ts # Server tests ├── newman-runner.test.ts # Runner tests └── fixtures/ # Test fixtures └── sample-collection.json ``` ### Running Tests ```bash # Run tests pnpm test # Run tests with coverage pnpm test:coverage ``` ### Building ```bash # Build the project pnpm build # Clean build artifacts pnpm clean ``` ## Contributing 1.
