Buttondown MCP Server

# Project Implementation Plan ## Overview This plan outlines the implementation sequence for the Buttondown API client, following a test-driven development approach. Each chunk represents a discrete, testable unit of work. ## Implementation Sequence ### Phase 1: Core Infrastructure (✅ Completed) - TypeScript setup - pnpm workspace - ESLint configuration - Jest setup - Build process - Git repository ### Phase 2: API Client (✅ Completed) - Base HTTP client - Authentication system with lazy validation - Request/response types - Error handling - Email management with status filtering - Scheduling system with ISO 8601 support - Analytics retrieval - Efficient API key handling ### Phase 3: Interfaces (🚧 Current Focus) #### CLI Interface (Chunk 01) - Command parser - Command executors - CLI entry point - Integration tests - Documentation #### ModelContextProtocol Interface (Chunk 02) (✅ Core Features Completed) - Protocol handler - Command processor - Response formatter - Tool implementations: - list_emails with status filtering ✅ - create_draft ✅ - get_analytics ✅ - schedule_draft with ISO 8601 support ✅ - Parameter validation with Zod ✅ - Tool descriptions ✅ - Inspector support ✅ - Integration tests (In Progress) - Documentation (In Progress) ### Phase 4: Documentation & Polish (🚧 In Progress) - API documentation - Usage examples - Contributing guidelines - README updates - Final integration tests - MCP tool documentation - API key setup guide - Scheduling guide ## Dependencies ```mermaid graph TD A[Core Infrastructure] --> B[API Client] B --> C[CLI Interface] B --> D[ModelContextProtocol] C --> E[Documentation] D --> E F[MCP SDK] --> D ``` ## Risk Assessment ### High Risk Areas 1. API rate limiting 2. Error handling edge cases 3. State management in ModelContextProtocol 4. Email scheduling edge cases 5. API key validation timing ### Mitigation Strategies 1. Implement rate limiting detection and backoff 2. Comprehensive error test cases 3. Clear state management documentation 4. Thorough schedule validation 5. Efficient API key validation ## Timeline 1. CLI Interface (Chunk 01) - Estimated: 3-4 days - Dependencies: Core API client - Status: Not started 2. ModelContextProtocol (Chunk 02) - Estimated: 2-3 days - Dependencies: Core API client, MCP SDK - Status: Core features complete, testing and documentation in progress - Completed: - Tool implementations - Parameter validation - Inspector support - API key optimization - Email scheduling - Remaining: - Integration tests - Documentation - Error handling improvements 3. Documentation & Polish - Estimated: 2-3 days - Dependencies: All interfaces complete - Status: In progress - Focus areas: - MCP tool documentation - API key setup guide - Scheduling documentation - Error handling guide ## Check-in Points 1. After CLI interface completion: - All commands working - Integration tests passing - Documentation started 2. After ModelContextProtocol completion: - Protocol handler working ✅ - LLM interaction verified ✅ - Tool implementations complete ✅ - Parameter validation working ✅ - Inspector support added ✅ - API key optimization implemented ✅ - Email scheduling working ✅ - Integration tests passing (In Progress) - Documentation complete (In Progress) 3. Final review: - All features complete - Documentation comprehensive - All tests passing - API key handling optimized - Email scheduling validated
