Brings GroupDocs.Comparison's document diffing engine to Claude and other MCP clients as two callable tools: Compare produces marked-up result files and change counts for PDF, Word, Excel, PowerPoint, and 30+ formats, while GetDocumentInfo inspects page counts, dimensions, and metadata without running a full comparison. Handles password-protected files. Ships as a .NET global tool or Docker image, runs via dnx with optional version pinning, and lets you ask natural-language questions like "what changed between contract-v1.docx and contract-v2.docx?" The agent picks the right tool based on whether you're diffing or just inspecting. Includes a full integration test suite that exercises published artifacts across platforms, so the setup snippets are verified end to end.
