Wraps the GroupDocs.Redaction .NET library so Claude and other MCP clients can scrub sensitive data from documents on demand. Exposes five tools: RedactText for pattern matching, EraseMetadata for stripping author and company fields, RedactAnnotations for removing comments, RedactImageArea for drawing solid boxes over page regions, and GetDocumentInfo for inspecting file structure. Runs via dnx with no install step, as a global dotnet tool, or in Docker. Writes redacted files back to disk with a _redacted suffix. You'll need libgdiplus on Linux and macOS for image redaction unless you use the Docker image. Useful when you want AI agents to handle document sanitization without leaving the chat interface or piping files through external scripts.
