💻 Technical Details

Architecture

TextToolkit is built using the Model Context Protocol (MCP) specification, which allows it to integrate seamlessly with Claude Desktop and other MCP-compatible clients. The server is implemented in TypeScript and uses the following architecture:

• Core Services: Implements text transformation, encoding/decoding, and formatting
• MCP Server: Handles JSON-RPC requests from clients
• Utility Functions: Provides helper functions for text operations
• Testing Framework: Includes comprehensive test scripts for verifying functionality

Dependencies

• change-case - For case transformation operations
• crypto-js - For hash generation
• js-beautify - For code formatting and beautification
• uuid - For UUID generation and validation
• lorem-ipsum - For placeholder text generation
• @modelcontextprotocol/sdk - For MCP server implementation

Requirements

• Node.js 16.x or higher
• npm 7.x or higher
