MCP server for GroupDocs.Watermark — add and search document watermarks via AI agents.
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.
MCP server that exposes GroupDocs.Watermark as AI-callable tools for Claude, Cursor, GitHub Copilot, and other MCP agents.
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 storageAddImageWatermark — Adds an image watermark (logo, signature scan, stamp) to a document and saves the watermarked file. Configurable opacity + rotationSearchWatermarks — Finds existing watermarks (text + image) in a document and returns their details (type, text, page, position, size, rotation) as JSONRemoveWatermarks — Removes existing watermarks from a document and saves the cleaned copy. Optional text filter to remove only matching watermarksGetDocumentInfo — Returns the file type, page count, and per-page dimensions of a document as JSON — without modifying itYou 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.
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.
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.
