The key changes include: 1. Added specific checkboxes for each task within major sections 2. Organized implementation steps in a more granular way 3. Added checklists to the timeline sections 4. Converted all action items into checkable tasks 5. Kept the code examples for reference while implementing each section The format now makes it easier to: - Track progress on specific tasks - See what needs to be done in each section - Follow the implementation order - Reference example code while implementing Would you like me to: 1. Add more specific checkboxes for any section? 2. Break down any particular task into more granular steps? 3. Add more detailed examples for any specific component? --- _**User**_ now read this doc as if you were the developer who had to execute it, do you need any other info? --- _**Assistant**_ Let me analyze this from a developer's perspective and identify what additional information or clarification I would need to execute this plan effectively. Key Missing Information: 1. Project-Specific Details: - What is the actual purpose/functionality of this MCP server? The examples show generic code, but I need to know what specific tools and resources we need to implement. - What external APIs or services will we be integrating with? - What are the actual environment variables we need beyond the example ones? 2. Development Environment: - What version of Node.js/TypeScript should we use? - Are there any specific version requirements for dependencies? - Do we have an existing package.json or should we create one? 3. Testing Requirements: - What are the specific test cases we need to cover? - Are there any performance benchmarks we need to meet? - What's our target code coverage percentage? 4. Security Requirements: - What are the specific security requirements for our use case? - Are there any specific rate limiting thresholds we need to implement? - Do we need to implement any specific authentication mechanism? Let me check the current project structure to see what we're working with. --- Read file: package.json --- Let me also check if there's a README that might provide more context. --- Read file: README.md --- Based on the package.json and README.md, I now have a much better understanding of what we're building. This is a Readwise integration server that needs to implement MCP protocol to allow AI assistants to interact with Readwise data. However, I still need a few clarifications to execute the implementation plan effectively: 1. Readwise API Integration: - We need to add Readwise API client implementation to the tools - Need to define schemas for Readwise data types (books, highlights, etc.) - Need to implement proper error handling for Readwise API responses 2. Additional Required Tools: - `get_highlights` - `get_books` - `get_documents` - `search_highlights` 3. Required Prompts: - `readwise_highlight` for processing highlights - `readwise_search` for searching and processing highlights 4. Environment Variables: - Need to add `READWISE_API_KEY` to the environment schema - Need to handle API key validation during setup Let me propose an updated first step that's more specific to this project: 1. First Implementation Tasks: ```bash # Create the directory structure mkdir -p src/{server,shared,tests} # Create server files touch src/server/index.ts touch src/server/resources.ts touch src/server/tools.ts touch src/server/prompts.ts # Create shared utility files touch src/shared/config.ts touch src/shared/readwise-client.ts touch src/shared/types.ts touch src/shared/cache.ts # Create test files touch tests/server.test.ts touch tests/readwise-client.test.ts touch tests/tools.test.ts ``` Would you like me to: 1. Create a more detailed implementation plan specific to the Readwise integration? 2. Start implementing any specific component? 3. Add more detailed specifications for the Readwise-specific tools and resources? The current plan is good as a general MCP server guide, but we should adapt it to include the specific Readwise functionality we need to implement. --- _**User**_ keep this plan and create an additional one for readwise based of this but with the specific info you just suggested. --- _**Assistant**_ I'll create a Readwise-specific implementation plan while keeping our general MCP server plan. Let me create this as a separate file. --- ```diff - + # Readwise MCP Implementation Plan + + ## Overview + This plan details the Readwise-specific implementation requirements for our MCP server, focusing on integrating Readwise's functionality for accessing highlights, books, and documents through the MCP protocol. + + ## 1.

MCP Tools Implementation + + ### 2.1 Get Highlights Tool + - [ ] Implement highlight retrieval + - [ ] Add filtering options + - [ ] Implement pagination + - [ ] Add sorting options + + Example implementation (src/server/tools/get-highlights.ts): + ```typescript + server.tool( + "get_highlights", + { + book_id: z.number().optional(), + page: z.number().optional(), + limit: z.number().optional(), + sort_by: z.enum(["highlighted_at", "created_at", "updated"]).optional() + }, + async ({ book_id, page = 1, limit = 20, sort_by = "highlighted_at" }) => { + try { + const highlights = await readwiseClient.getHighlights({ + book_id, + page, + limit, + sort_by + }); + + return { + content: [{ + type: "text", + text: JSON.stringify(highlights) + }] + }; + } catch (error) { + return { + content: [{ + type: "text", + text: `Error fetching highlights: ${error.message}` + }], + isError: true + }; + } + } + ); + ``` + + ### 2.2 Get Books Tool + - [ ] Implement book listing + - [ ] Add category filtering + - [ ] Add search functionality + - [ ] Implement pagination + + ### 2.3 Get Documents Tool + - [ ] Implement document retrieval + - [ ] Add format options + - [ ] Add metadata support + - [ ] Implement caching + + ### 2.4 Search Highlights Tool + - [ ] Implement full-text search + - [ ] Add tag filtering + - [ ] Add date range filtering + - [ ] Implement relevance sorting + + ## 3. Resource Definitions + + ### 3.1 User Configuration Resource + - [ ] Create user preferences schema + - [ ] Implement API key storage + - [ ] Add configuration validation + + Example implementation (src/server/resources/config.ts): + ```typescript + const UserConfigSchema = z.object({ + apiKey: z.string().min(1), + defaultLimit: z.number().default(20), + cacheTimeout: z.number().default(300) + }); + + server.resource( + "user-config", + "config://readwise/user", + async (uri) => ({ + contents: [{ + uri: uri.href, + text: JSON.stringify({ + apiKey: process.env.READWISE_API_KEY, + defaultLimit: 20, + cacheTimeout: 300 + }) + }], + schema: UserConfigSchema + }) + ); + ``` + + ### 3.2 Cache Resources + - [ ] Implement book cache + - [ ] Implement highlight cache + - [ ] Add cache invalidation + - [ ] Add cache statistics + + ## 4. Environment Setup + + ### 4.1 Required Environment Variables + - [ ] READWISE_API_KEY + - [ ] CACHE_TIMEOUT + - [ ] MAX_REQUESTS_PER_MINUTE + - [ ] DEFAULT_PAGE_LIMIT + + Example implementation (src/shared/config.ts): + ```typescript + const envSchema = z.object({ + READWISE_API_KEY: z.string().min(1), + CACHE_TIMEOUT: z.string().transform(Number).default("300"), + MAX_REQUESTS_PER_MINUTE: z.string().transform(Number).default("60"), + DEFAULT_PAGE_LIMIT: z.string().transform(Number).default("20") + }); + + export const config = envSchema.parse(process.env); + ``` + + ## 5. Testing Requirements + + ### 5.1 API Tests + - [ ] Test API key validation + - [ ] Test rate limiting + - [ ] Test error handling + - [ ] Test response parsing + + ### 5.2 Tool Tests + - [ ] Test highlight retrieval + - [ ] Test book listing + - [ ] Test document access + - [ ] Test search functionality + + ### 5.3 Integration Tests + - [ ] Test end-to-end workflows + - [ ] Test caching behavior + - [ ] Test error scenarios + - [ ] Test performance requirements + + ## Implementation Timeline + + ### Week 1: Core Integration + - [ ] Set up Readwise API client + - [ ] Implement data types + - [ ] Add basic tool implementations + - [ ] Set up configuration + + ### Week 2: Features and Testing + - [ ] Complete all tool implementations + - [ ] Implement caching + - [ ] Add comprehensive tests + - [ ] Add error handling + + ### Week 3: Optimization and Documentation + - [ ] Optimize performance + - [ ] Add rate limiting + - [ ] Complete documentation + - [ ] Final testing and fixes + + ## Notes + - API rate limits: Be mindful of Readwise's API rate limits + - Caching: Implement aggressive caching to minimize API calls + - Error handling: Provide clear error messages for API issues + - Security: Never expose the API key in responses + - Testing: Use mock responses for testing to avoid API rate limits ``` --- --- ---
