Added

• DXT Extension Support: Complete restructuring to support Anthropic DXT (Desktop Extensions) packaging format
• DXT-compliant directory structure with server/ containing bundled dependencies and entry point
• New server/main.py entry point following official DXT conventions
• Automated DXT package building via GitHub Actions workflow (.github/workflows/dxt-release.yml)
• Bundled dependencies in server/lib/ directory for self-contained extension deployment
• Updated manifest.json with proper DXT configuration and PYTHONPATH setup
• DXT installation instructions as primary recommended installation method in README
• Automated release workflow that builds both Docker images and DXT packages
• DXT package validation and testing scripts

Changed

• Project Structure: Restructured from src/ layout to DXT-compliant server/ layout
• Installation Priority: DXT extension is now the primary recommended installation method
• README.md: Completely reorganized to prioritize DXT installation while preserving all existing content
• Dependency Management: Moved from runtime dependency installation to bundled dependencies approach
• Entry Point: Changed from python -m propublica_mcp.server to python server/main.py
• PYTHONPATH Configuration: Updated to use ${__dirname}/server/lib:${__dirname}/server for DXT compatibility

Fixed

• Module resolution issues when running as DXT extension by implementing proper sys.path setup
• Virtual environment compatibility by bundling all dependencies in extension package
• Runtime dependency conflicts by using vendored dependencies approach

Technical Details

• Maintains full backward compatibility with existing Docker and Python installation methods
• Supports hybrid deployment strategy (DXT for local, Docker for production)
• Automatic GitHub release creation with both Docker images and DXT packages
• Enhanced CI/CD pipeline for multi-format package distribution

Changed

• BREAKING: Implemented proper Streamable HTTP transport according to MCP 2025-03-26 specification
• BREAKING: Server now uses single / endpoint for all MCP communication instead of separate /sse and /messages
• BREAKING: HTTP transport now properly handles both GET and POST requests as per MCP specification
• Tool responses now use correct MCP format with content array and isError flag

Fixed

• FastMCP integration for proper tool listing and calling
• Improved JSON-RPC message handling and error responses
• Enhanced session management and security validation
• Updated health check endpoint with transport and version information

Added

• HTTP/SSE server support for cloud deployment compatibility
• Auto-detection of cloud deployment environments (PORT, DO_APP_URL, etc.)
• Health check endpoints (/health and /) for cloud platform monitoring
• Starlette and Uvicorn dependencies for HTTP server functionality
• Support for both stdio (local MCP usage) and HTTP/SSE (cloud deployment) modes
• DigitalOcean App Platform deployment configuration with PORT environment variable

Changed

• Server automatically switches between stdio and HTTP modes based on environment
• Enhanced deployment template for DigitalOcean with proper cloud configuration
• Moved integration tests to proper /tests/ directory for better organization
• Updated import paths in test files for correct module resolution

Fixed

• DigitalOcean deployment template source conflict (git vs github configuration)
• Docker LABEL parsing error caused by unescaped apostrophe in description
• Docker build failures on cloud platforms due to invalid LABEL syntax
• Project structure cleanup by removing accidentally committed virtual environment

Added

• New get_most_recent_pdf MCP tool that finds the most recent Form 990 PDF filing for an organization
• New get_most_recent_pdf_filing method in API client that iterates through all filings to find the newest PDF
• One-click deployment buttons for DigitalOcean App Platform and Cloudflare Workers
• Comprehensive deployment guide (DEPLOYMENT.md) for cloud platforms
• Cloud deployment configurations (.do/deploy.template.yaml and wrangler.toml)

Changed

• Improved PDF detection logic to iterate through all filings starting from most recent year
• Updated README with deployment buttons and cloud deployment instructions

Fixed

• PDF availability detection now correctly finds older PDFs when recent years don't have PDFs available
• Fixed issue where organizations with PDFs available would incorrectly show "no PDFs found"

Fixed

• Docker tag mismatch in GitHub workflow where images were published without v prefix (e.g., 0.1.3) but workflow was trying to reference them with v prefix (e.g., v0.1.3)
• Updated all Docker tag references in workflow to strip v prefix for consistency with published image tags

Added

• Initial project structure setup
• ProPublica MCP Server implementation plan
• Entity Relationship Diagram for data modeling
• Project documentation (README, requirements, etc.)
• Basic FastMCP server framework integration
• Complete MCP server implementation with 6 tools:
  • search_nonprofits - Search for nonprofit organizations
  • get_organization - Get detailed organization information
  • get_organization_filings - Get Form 990 filings
  • analyze_nonprofit_financials - Analyze financial trends
  • search_similar_nonprofits - Find similar organizations
  • export_nonprofit_data - Export data for CRM integration
• Comprehensive data models with validation
• API client with rate limiting and error handling
• Full test suite with 30+ tests passing
• Docker support with multi-stage builds
• Docker Compose configuration for easy deployment
• GitHub Actions workflow for automated Docker publishing
• GitHub Container Registry integration
• Multi-architecture Docker images (linux/amd64, linux/arm64)
• Security scanning with Trivy
• Docker publishing script for manual deployments
• Proper logging configuration for MCP protocol compatibility
