Documentation Overview
GroupDocs.Total MCP Server
Unified MCP server that exposes the full GroupDocs.Total document-processing toolset — annotation, comparison, conversion, markdown, merging, metadata, parsing, redaction, signing, watermarking, plus cross-product document inspection and page preview — as AI-callable tools for Claude, Cursor, GitHub Copilot, and other MCP agents. Designed to be used standalone — attaching the individual product MCPs (GroupDocs.Annotation.Mcp, GroupDocs.Signature.Mcp, …) alongside is unnecessary and would duplicate tools.

Installation
One-click installs pre-fill every supported setting: edit the placeholder host path in the volume mount after install; an empty GROUPDOCS_LICENSE_PATH runs in evaluation mode.
More clients - ready-made configs for Claude Code, Codex CLI, Visual Studio 2022, Cursor, Windsurf, Cline, and JetBrains Rider live in
install/generated/.
This product ships via Docker (GHCR) only. GroupDocs.Total bundles every engine (including Parser's embedded ONNX models), so the packed tool far exceeds NuGet.org's 250 MB limit - so dnx and
dotnet tool install are not available for it. When upstream ships a
slimmer engine that packs under the limit, the standard NuGet flow returns
(see the revert notes in .github/workflows/publish_prod.yml).
Images are multi-arch (linux/amd64 + linux/arm64), tagged latest plus an
immutable version tag per release (e.g. :26.9.0). To pin, replace :latest
with the version tag - recommended for shared configs and CI.

Licensing
The MCP server itself is MIT; the underlying GroupDocs engines require a license for production use. Without one the server runs in evaluation mode:
- Each bundled engine applies its own evaluation limits: output watermarks / evaluation notices, page limits, and per-process document-open caps (1-15 documents depending on the engine).
To lift the limits, mount your GroupDocs.Total.lic into the container and point
GROUPDOCS_LICENSE_PATH at it (see the Claude Desktop example above):
Configuration
| Variable | Description | Default |
|---|---|---|
GROUPDOCS_MCP_STORAGE_PATH | Base folder for input and output files | current directory |
GROUPDOCS_MCP_OUTPUT_PATH | (Optional) separate folder for output files | GROUPDOCS_MCP_STORAGE_PATH |
GROUPDOCS_LICENSE_PATH | Path to GroupDocs license file | (evaluation mode) |
