Let AI agents work with documents through the GroupDocs engines, locally over MCP: 38 tools for annotation, comparison, conversion, Markdown, merging, metadata, parsing, redaction, signing and watermarking, plus document info and page previews. No uploads; without a license it runs in evaluation mode.

• GroupDocs.Total.Mcp: The MCP server (MIT), with one-click installs for VS Code and Cursor and configs for Claude Code, Codex CLI, Visual Studio 2022, Windsurf, Cline and JetBrains Rider. It ships as a Docker image only: the engines exceed NuGet's 250 MB limit.
• GroupDocs.Mcp.Installer: Cross-platform installer that registers the server with your MCP clients and verifies it.
• GroupDocs.Total.Mcp.Tests: Integration tests for the server.

# Run the server on the documents folder, then ask your agent:
docker run --rm -i -v $(pwd)/documents:/data ghcr.io/groupdocs-total/total-net-mcp:latest

"Convert contract.docx to PDF, then sign it with a QR code containing 'Signed by Alice', then watermark every page with 'CONFIDENTIAL'" "Compare old.pdf and new.pdf, list every annotation in the result, and preview page 1"

Docker image | MCP Registry

• Document intake pipelines: convert incoming files to PDF, then watermark, sign and archive them in one service.
• Review and approval: render documents in the browser, compare versions, and collect annotations and comments.
• Privacy and compliance: redact personal data, remove metadata, and verify signatures before documents leave the organization.
• Search and data extraction: index document stores for full-text search, and extract text, tables, images and barcodes.
