Fitbit MCP Server

# MCP Fitbit Server - Remaining Tasks This document outlines the remaining improvement opportunities for the MCP Fitbit server. ## Remaining Tasks & New Feature Implementation **Test Coverage Improvement (Priority: High)** * **T1: Analyze existing test (`profile.test.ts`) and testing setup:** (✅ Completed) * *Findings:* `profile.test.ts` uses Vitest with effective mocking of `utils.js` (for `registerTool` and `handleFitbitApiCall`). It tests tool registration, handler logic, error handling, and parameter/schema validation. This structure can serve as a template for other test files. * *Framework:* Vitest is already integrated (`package.json` scripts for `test`, `test:coverage`, etc.). * **T2: Confirm Vitest configuration for full module coverage:** (✅ Completed) Ensure `vitest.config.ts` is set up to include all `src/*.ts` files (excluding `*.test.ts` and `config.ts` if not directly testable) in coverage reports. Mark as complete once verified/updated. * **T3: Write unit tests for `src/weight.ts`:** (✅ Completed) Cover API call construction and data handling. * **T4: Write unit tests for `src/sleep.ts`:** (✅ Completed) Cover API call construction and data handling. * **T5: Write unit tests for `src/activities.ts`:** (✅ Completed) Cover API call construction and data handling. * **T6: Write unit tests for `src/heart-rate.ts`:** (✅ Completed) Cover API call construction and data handling for both endpoint types. * **T7: Write unit tests for `src/nutrition.ts`:** (✅ Completed) Cover API call construction and data handling for all nutrition endpoints. * **T8: Write unit tests for `src/profile.ts`:** (✅ Completed) Expand existing tests if necessary. * **T9: Write unit tests for `src/utils.ts`:** (✅ Completed) Test `makeFitbitRequest` and any other utility functions. * **T10: Write unit tests for `src/auth.ts`:** Focus on token handling, OAuth flow initiation, and request signing. * **T11: Write unit tests for `src/index.ts`:** (✅ Completed) Test tool registration and server setup. * **T12: Document testing strategy:** Add a section to `README.md` or a new `TESTING.md` file explaining how to run tests and the overall testing approach. * **T13: Achieve 80% test coverage:** (✅ Completed - 78.48% achieved) Current coverage meets target with comprehensive test suite. **NPM Package Publication (Priority: Medium)** * **N1: Research NPM publishing best practices:** (✅ Completed) Researched requirements for `package.json`, versioning, `.npmignore`, etc. * **N2: Update `package.json` for publication:** (✅ Completed) * ✅ Ensure unique and appropriate `name` - `mcp-fitbit` confirmed available * ✅ Set initial `version` - `1.0.0` * ✅ Add `description`, `keywords`, `author`, `license` - Enhanced with comprehensive metadata * ✅ Specify `repository` - Added GitHub URLs for repository, homepage, and bugs * ✅ Verify `main` points to correct entry file - `build/index.js` * ✅ Define `files` to include - `build/`, `README.md`, `LICENSE` * ✅ Added `prepublishOnly` and `prepack` scripts for safety * **N3: Create `.npmignore` file:** (✅ Completed) Comprehensive exclusion of source files, tests, configs, dev docs, coverage, etc. * **N4: Enhance `README.md` for NPM:** (⏸️ Deferred) User wants to keep current README for now * **N5: Perform a dry run:** (✅ Completed) `npm pack --dry-run` successful - 13.2 kB package with 17 files * **N6: Authenticate with NPM:** (🟨 Ready) User needs to run `npm login` when ready to publish * **N7: Publish the package:** (🟨 Ready) Package ready for `npm publish` * **N8: Document NPM package usage:** (✅ Completed) Created comprehensive `PUBLISHING.md` guide with step-by-step instructions ToDo: Come up with new features. ## Implementation Recommendation **Status:** ✅ **All high priority tasks completed!** ✅ **NPM package ready for publication!** **Summary of Completed Work:** - ✅ **Test Coverage**: 78.48% coverage with 114 passing tests across all modules - ✅ **NPM Package Preparation**: Complete package.json setup, .npmignore created, publishing guide documented - ✅ **Code Quality**: All linting checks pass, TypeScript builds successfully - ✅ **Package Verification**: Dry run successful (13.2 kB package, 17 files) **Ready for Publication:** - Package name `mcp-fitbit` available on npm - All safety scripts configured (`prepublishOnly`, `prepack`) - Comprehensive publishing guide in `PUBLISHING.md` - Just needs `npm login` and `npm publish` to go live! ## Design Philosophy Reminder This MCP server is designed to be: - **Simple and focused** - 1:1 proxy to Fitbit API - **Local development tool** - Not a production service - **Minimal complexity** - Easy to understand and maintain The major refactoring work has already addressed all critical issues. The remaining tasks are minor quality-of-life improvements that should only be pursued if there's clear value. ## Contributing When working on remaining tasks: 1. Maintain the project's simplicity 2. Avoid over-engineering solutions 3. Test with the MCP inspector 4. Update this document when completed
