This project builds an intelligent observability agent using the MCP protocol and LangGraph, which can automatically analyze microservice logs and monitoring data to help developers quickly diagnose production environment issues. This article introduces its architectural design, core components, and typical application scenarios.

Section 02
In microservice architectures, engineers often need to answer the following questions:
The traditional workflow involves: opening Grafana to check metric trends, switching to Splunk or Graylog to query relevant logs, jumping back and forth between multiple systems, and manually correlating trace IDs of different services. This process is time-consuming and prone to missing key information.
The core insight of Agentic Microservices is: if these scattered data sources can be uniformly exposed to LLM, allowing AI to automatically perform correlation analysis, the efficiency of troubleshooting will be greatly improved.
Section 03
The project adopts a two-layer architecture:
Section 04
The MCP (Model Context Protocol) server implemented based on Spring AI is responsible for reading aggregated logs and monitoring data. It uniformly encapsulates access to underlying data sources, including:
The value of the MCP protocol lies in standardizing the interaction interface between AI and external tools. Any MCP-compatible client can call this server without caring about the specific implementation of the underlying data storage.
Section 05
The observability-debug-agent built based on LangGraph is responsible for coordinating the analysis process:
LangGraph's graph structure allows defining complex multi-step workflows, and the agent can decide the next action based on intermediate results to achieve true autonomous analysis.
Section 06
The project's technology selection reflects best practices in cloud-native and AI engineering:
This technology combination balances the maturity of the enterprise-level Java ecosystem and the advancement of AI engineering frameworks.

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.
