26.5.0

Initial public release of GroupDocs.Comparison MCP Server

What changed

• NuGet package GroupDocs.Comparison.Mcp published with McpServer package type.
• Two MCP tools exposed:
  • Compare — compare two documents (source vs target), produce a marked-up result file with the differences highlighted, and return a change-count summary. Supports PDF, Word, Excel, PowerPoint, ODT, RTF, TXT, HTML, and 30+ more formats; takes optional sourcePassword / targetPassword for protected documents.
  • GetDocumentInfo — inspect a single source document and return file type, page count, file size, and per-page dimensions as JSON. No comparison performed. Optional password for protected documents.
• Installable via dnx GroupDocs.Comparison.Mcp@26.5.0 --yes (.NET 10 SDK required) or dotnet tool install -g.
• Docker image published to ghcr.io/groupdocs-comparison/comparison-net-mcp and docker.io/groupdocs/comparison-net-mcp.
• Environment variables: GROUPDOCS_MCP_STORAGE_PATH, optional GROUPDOCS_MCP_OUTPUT_PATH, GROUPDOCS_LICENSE_PATH.
• Linux native graphics deps wired up: SkiaSharp.NativeAssets.Linux.NoDependencies (3.119.0) is referenced because GroupDocs.Comparison's nuspec already declares the SkiaSharp managed and native packages — we pin explicitly so transitive resolution stays deterministic. libgdiplus + libfontconfig1 are installed in the Docker image and the System.Drawing.EnableUnixSupport runtime flag is set because Comparison's Cells (Excel) and image-format paths still call System.Drawing.Common.

Why

Third product MCP server in the GroupDocs MCP framework (after Metadata and Conversion). Exposes
GroupDocs.Comparison for .NET as an AI-callable tool for Claude, Cursor,
VS Code / GitHub Copilot, and other MCP-compatible agents.
