Local serverstdio

What is the Groupdocs MCP server?

Groupdocs MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server for GroupDocs.Watermark — add and search document watermarks via AI agents.

What you get

MCP server that exposes GroupDocs.Watermark as AI-callable tools for Claude, Cursor, GitHub Copilot, and other MCP agents.

What the assistant can call

Once Groupdocs is connected, these are the calls the assistant has available:

  • AddWatermark — Adds a text watermark (Arial, configurable size + rotation) to a document and saves the watermarked file to storage
  • AddImageWatermark — Adds an image watermark (logo, signature scan, stamp) to a document and saves the watermarked file. Configurable opacity + rotation
  • SearchWatermarks — Finds existing watermarks (text + image) in a document and returns their details (type, text, page, position, size, rotation) as JSON
  • RemoveWatermarks — Removes existing watermarks from a document and saves the cleaned copy. Optional text filter to remove only matching watermarks
  • GetDocumentInfo — Returns the file type, page count, and per-page dimensions of a document as JSON — without modifying it

Configuration and credentials

You will need 3 environment variables: GROUPDOCS_MCP_STORAGE_PATH, GROUPDOCS_LICENSE_PATH, GROUPDOCS_MCP_OUTPUT_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Choosing this one

This sits in the file and storage access group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Groupdocs's toolset — AddWatermark, AddImageWatermark, SearchWatermarks and 2 more — is a fair guide to whether it matches your workflow. It is maintained by groupdocs-watermark; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Groupdocs's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the groupdocs mcp server does with a few real requests.

Frequently asked questions

It connects Groupdocs to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (AddWatermark, AddImageWatermark, SearchWatermarks, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Groupdocs directly.
