Document extraction engine for PDFs, Office files and scans, shipped as an agent plugin, MCP server and CLI

PluginMedium risk

xberg-io/xbergAuthor: Kreuzberg, Inc.

Install

/plugin marketplace add xberg-io/xberg
/plugin install xberg@xberg

This is third-party code. Review the repository files before installing.

What it does

Xberg parses more than a hundred document formats: PDF, Word, Excel, slides, email, e-books, archives and images. It returns clean text or Markdown, tables, metadata and images, with OCR for scans via Tesseract, PaddleOCR or vision models. The plugin gives the agent skills for batch processing, OCR, table and keyword extraction, chunking and picking an output format. The same engine runs as an MCP server with xberg mcp, so the agent can call extraction directly instead of shelling out.

Who it is for. For RAG developers, analysts and anyone who needs an agent to read documents locally without cloud services.

Good fit when

  • You need text and tables from a batch of PDFs or scans
  • You are building RAG and need document parsing with chunking
  • The agent writes Python, Node.js or Rust code that calls Xberg

Not a fit when

  • You only need to read one plain text file
  • You cannot install native binaries or Docker on the machine

Example request

Extract all tables from these PDF reports as Markdown and use OCR for the scanned ones

Limitations

The MCP server needs the xberg CLI installed (brew, Scoop or Docker). Some features such as transcription and URL ingestion are behind build flags. LLM-based structured extraction needs a local model or a provider key. The project was recently renamed from Kreuzberg to Xberg, so older guides may use previous package names.

How to disable. Uninstall the xberg plugin via /plugin in Claude Code or the equivalent command in another agent, and remove the xberg block from your MCP config.

Security check

  • Runs a native binary and reads project files
  • Makes network requests when URL ingestion is enabled

README in short

The README covers a Rust core with bindings for about fifteen languages and several ways to run it: library, CLI, REST API, MCP server, Docker and Helm. It lists supported formats, OCR backends, layout and table models, embeddings and text enrichment. A separate section explains installing the plugin in Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI, Factory Droid and opencode. MIT licensed.
