Configuration Leave feedback

Configure the GroupDocs.Parser MCP server through one config file — the installer’s groupdocs-mcp.config.json — or directly on the docker run command line:

{
  "channel":     "docker",
  "registry":    "ghcr",
  "clients":     ["claude-desktop", "vscode"],
  "version":     "latest",
  "storagePath": "D:/Storage/Documents",
  "outputPath":  "D:/Storage/Output",
  "licensePath": "D:/Storage/Licenses/GroupDocs.Parser.lic",
  "products":    ["parser"]
}

• channel — docker is the only option for this product.
• storagePath — the host folder mounted into the container as /data (created if missing).
• outputPath — optional separate folder for extracted images and files; empty = same as storage.
• licensePath — empty string = evaluation mode (safe, no error); see Licensing.
• version — "latest" or a pin such as "26.9.0". Pinning is recommended for shared/committed configs.

The same settings travel as environment variables, passed before the image name:

The distinction that trips people up: these paths are container paths, not host paths. /data is whatever host folder you mounted there.

docker run --rm -i \
  -v /path/to/documents:/data \
  -v /path/to/license-folder:/license:ro \
  -e GROUPDOCS_MCP_STORAGE_PATH=/data \
  -e GROUPDOCS_LICENSE_PATH=/license/GroupDocs.Parser.lic \
  ghcr.io/groupdocs-parser/parser-net-mcp:latest

• storagePath → /data
• outputPath → /data/output (when set)
• license folder → /license:ro, read-only

Metered keys can be forwarded by name so they never appear in a config file:

docker run --rm -i -v /path/to/documents:/data \
  -e GROUPDOCS_MCP_STORAGE_PATH=/data \
  -e GROUPDOCS_METERED_PUBLIC_KEY -e GROUPDOCS_METERED_PRIVATE_KEY \
  ghcr.io/groupdocs-parser/parser-net-mcp:latest

For container fleets without client registration, generate a docker-compose.yml:

./install-groupdocs-mcp.ps1 -EmitCompose -Clients @()
