DeepWriter MCP Server

# Tech Context: DeepWriter MCP Server ## Technologies Used - **Node.js**: Server runtime for JavaScript/TypeScript. - **TypeScript**: Strong typing for reliability and maintainability. - **fetch (node-fetch or native)**: HTTP requests to DeepWriter API. - **dotenv**: Manage environment variables securely. - **Jest or Mocha**: Testing framework for unit and integration tests. - **Winston or pino**: Logging library for structured logs. ## Development Setup - Node.js (LTS) and npm/yarn required. - TypeScript configuration for strict type checking. - .env file for local development (never commit API keys). - Scripts for build, test, and start. ## Technical Constraints - All API requests must use HTTPS. - API keys must never be logged or exposed. - Input/output must strictly follow provided schemas. - Error handling must cover all specified cases. - Rate limiting and retry logic must be implemented. ## Dependencies - node-fetch (or native fetch in Node 18+) - dotenv - typescript - jest/mocha (for testing) - winston/pino (for logging) - Additional MCP protocol libraries as needed ## Integration Points - DeepWriter API endpoints (as specified in the implementation guide). - MCP stdio or SSE protocol for tool communication. ## Security Considerations - Secure storage and handling of API keys. - Input sanitization and validation. - Regular dependency updates and vulnerability monitoring.
