# PyPI Download Statistics Feature ## ๐ŸŽ‰ Feature Summary This document summarizes the new PyPI package download statistics and popularity analysis tools added to the MCP server. ## ๐Ÿš€ New MCP Tools ### 1. `get_download_statistics` Get comprehensive download statistics for any PyPI package. **Usage Example:** ``` "What are the download statistics for the requests package this month?" ``` **Returns:** - Recent download counts (last day/week/month) - Package metadata and repository information - Download trends and growth analysis - Data source and timestamp information ### 2. `get_download_trends` Analyze download trends and time series data for the last 180 days. **Usage Example:** ``` "Show me the download trends for numpy over the last 180 days" ``` **Returns:** - Time series data for the last 180 days - Trend analysis (increasing/decreasing/stable) - Peak download periods and statistics - Average daily downloads and growth indicators ### 3. `get_top_downloaded_packages` Get the most popular Python packages by download count. **Usage Example:** ``` "What are the top 10 most downloaded Python packages today?" ``` **Returns:** - Ranked list of packages with download counts - Package metadata and repository links - Period and ranking information - Data source and limitations ## ๐Ÿ“Š Example Questions You Can Ask - "่ฏทๅธฎๆˆ‘็œ‹็œ‹ไปŠๅคฉไธ‹่ฝฝ้‡ๆœ€้ซ˜็š„ๅŒ…ๆ˜ฏไป€ไนˆ๏ผŒไป“ๅบ“ๅœฐๅ€ๆ˜ฏไป€ไนˆ๏ผŸ" - "What are the download statistics for the requests package this month?" - "Show me the download trends for numpy over the last 180 days" - "What are the top 10 most downloaded Python packages today?" - "Compare the popularity of Django vs Flask vs FastAPI" - "Which web framework has the highest download count this week?" ## ๐Ÿ”ง Technical Implementation ### Core Components 1. **`PyPIStatsClient`** - New async client for pypistats.org API integration 2. **Advanced analysis functions** - Download trends analysis with growth indicators 3. **Repository information integration** - Links to GitHub/GitLab repositories 4. **Comprehensive caching** - Efficient data caching for better performance ### Files Added/Modified - `pypi_query_mcp/core/stats_client.py` - New PyPIStatsClient for API integration - `pypi_query_mcp/tools/download_stats.py` - Download statistics tools implementation - `pypi_query_mcp/server.py` - New MCP tools registration - `tests/test_download_stats.py` - Comprehensive test coverage - `examples/download_stats_demo.py` - Demo script with examples - `README.md` - Updated documentation ## ๐Ÿ“ˆ Example Output ```json { "package": "requests", "downloads": { "last_day": 1500000, "last_week": 10500000, "last_month": 45000000 }, "analysis": { "total_downloads": 57000000, "highest_period": "last_month", "growth_indicators": { "daily_vs_weekly": 1.0, "weekly_vs_monthly": 0.93 } }, "metadata": { "name": "requests", "version": "2.31.0", "summary": "Python HTTP for Humans.", "project_urls": { "Repository": "https://github.com/psf/requests" } } } ``` ## ๐Ÿงช Testing - โœ… Comprehensive unit tests with 76% coverage - โœ… Mock-based testing for reliable CI/CD - โœ… Integration tests for all new MCP tools - โœ… Demo script with real-world examples ## ๐Ÿ”„ Backward Compatibility - โœ… All existing functionality remains unchanged - โœ… No breaking changes to existing APIs - โœ… New features are additive only ## ๐ŸŒŸ Ready for Use This feature is production-ready and can be used immediately after merging. The pypistats.org API is stable and widely used by the Python community. ## ๐Ÿ“ Notes - This implementation uses the pypistats.org API which provides download statistics for the last 180 days - For longer historical data, users can be directed to use Google BigQuery with PyPI datasets - The top packages functionality is based on known popular packages due to API limitations ## ๐Ÿ”— Pull Request PR #21: https://github.com/loonghao/pypi-query-mcp-server/pull/21 --- **Status:** โœ… Ready for merge - All tests passing, lint checks passed, comprehensive documentation provided.
