Initial public release of GroupDocs.Viewer MCP Server

What changed

  • NuGet package GroupDocs.Viewer.Mcp published with McpServer package type.
  • Two MCP tools exposed:
    • RenderPage — render a single document page as a PNG image. Returns a CallToolResult with both a TextContentBlock (saved file path: <source-stem>_page<N>.png) and an ImageContentBlock (PNG bytes inline as image/png). Supports PDF, Word, Excel, PowerPoint, ODT, RTF, HTML, and 170+ more formats; takes optional page (1-based, default 1) and password.
    • GetViewInfo — return file type, page count, and per-page dimensions as JSON. No rendering performed. Optional password for protected documents.
  • Installable via dnx GroupDocs.Viewer.Mcp@26.5.0 --yes (.NET 10 SDK required) or dotnet tool install -g.
  • Docker image published to ghcr.io/groupdocs-viewer/viewer-net-mcp and docker.io/groupdocs/viewer-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 (3.119.1) is referenced because GroupDocs.Viewer's nuspec 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 Viewer's Slides, image post-processing, archive-to-Word, mail/Outlook saving, and barcode generation paths still call System.Drawing.Common.

Why

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

RenderPage is the first tool in the GroupDocs MCP family to return a CallToolResult directly with an inline ImageContentBlock — AI clients can display the rendered page without a separate fetch.

Migration / impact

First release — no migration required.
