MetaMorph is an open-source LLM-driven Agent system specifically designed for metadata extraction, normalization, and structured transformation. It converts messy, unstructured, or heterogeneous dataset columns into machine-readable features, adopts an Agent workflow (multi-step LLM pipeline), and supports traceability tracking and HTML report generation.

MetaMorph is an open-source LLM-driven Agent system specifically designed for metadata extraction, normalization, and structured transformation．It converts messy, unstructured, or heterogeneous dataset columns into machine-readable features, adopts an Agent workflow (multi-step LLM pipeline), and supports traceability tracking and HTML report generation.
Section 02
Section 03
In machine learning projects, high-quality metadata is the foundation for building meaningful models. However, in real-world scenarios, metadata often exists in various messy formats: free-text columns (e.g., remarks, descriptions), inconsistent date and unit formats, misspelled classification labels, semi-structured strings, as well as undocumented conventions and hidden contexts. These issues lead to fragile models, reduced reproducibility, and slower iteration speeds.
MetaMorph is an open-source framework designed to address this pain point; it leverages the capabilities of large language models to convert messy metadata into structured, machine-readable formats, thereby enhancing machine learning pipelines and predictive models.
Section 04
Unlike traditional one-time prompts, MetaMorph adopts an Agent workflow architecture (supervisor + specialized nodes) to ensure the robustness of the transformation process:
This structure supports repeatable, testable LLM behavior and can safely scale to multiple columns and datasets.
Section 05
An important feature of MetaMorph is column-level traceability tracking. Each processed column maintains a tracker that records:
This means you can answer: "What changed, when did it change, and why did it change?"
Section 06
MetaMorph can be exposed as a local MCP (Model Context Protocol) server, allowing any MCP-compatible client (IDE Agent, desktop application, or other LLM orchestrators) to call it as a structured tool.
Section 07
The exposed MCP tools include:

MetaMorph has practical application value in multiple fields:

Nornir MCP Server is an enterprise-level server based on the Model Context Protocol (MCP). It seamlessly integrates large language models (such as Claude) with the Nornir network automation framework, supporting natural language orchestration for multi-vendor network devices (Cisco, Arista, Juniper, etc.), and providing production-grade features like a dual-engine architecture (NAPALM + Netmiko), intelligent filtering, and a secure sandbox.
Bibliothèque Française LLM is a structured indexing and annotation project for French public domain literature designed specifically for large language models (LLMs). It integrates multiple authoritative sources such as DraCor, Common Corpus, and Wikisource, providing metadata indexing categorized by genre, author, and era, as well as in-depth annotations for dramatic texts (including characters, lines, stage directions, etc.). Its aim is to enable LLMs to efficiently read and understand classic French literary works.
Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
