- Core concepts of MCP include StdioServerTransport for communication, McpServer for tool management, Tool for task execution, and Resource for data or state management.
- Usage examples of MCP involve the typescript-sdk for development, installation of necessary npm packages, and creating a visual testing tool using Playwright for UI testing.
- Important functions like login, auto-login, and visual test core function are implemented along with defining and configuring the MCP tool for UI testing.
- The project repository for the MCP visual test tool can be found at https://www.npmjs.com/package/@anguske/mcp-playwright-visual-test.
- Configuration details for Cursor usage, specifying environment variables for auto login, viewport dimensions, test threshold, and more, are crucial for tool execution.
- Adding a resource for test results and adhering to best practices like parameter validation, error handling, resource management, tool design, and configuration management are recommended.
- In conclusion, leveraging MCP framework facilitates building robust AI applications and adhering to best practices ensures code quality, maintainability, and user satisfaction.
