Archi FAQs

Question 1

Are modifications made by LLMs safe and reversible?

Accepted Answer

Yes, Archi prioritizes safety. All model mutations integrate with Archi's native CommandStack, making them undoable via Archi's undo/redo functionality. It also offers advanced safety features like human-in-the-loop approval mode and atomic batch operations.

Question 2

What is Archi and what does it do?

Accepted Answer

Archi is an Eclipse plugin for Archi that exposes ArchiMate models through the Model Context Protocol (MCP). It enables Large Language Models (LLMs) to query, analyze, and modify enterprise architecture models using natural language commands.

Question 3

How do LLMs interact with ArchiMate models using Archi?

Accepted Answer

Archi embeds an HTTP server that speaks MCP. Any MCP-compatible LLM client can connect to this server and use 51 comprehensive MCP tools to ask questions, search elements, compose views, and even create or modify model content through natural language prompts.

Question 4

What types of operations can LLMs perform on ArchiMate models?

Accepted Answer

LLMs can perform a wide range of operations, including model querying and inspection, element/relationship creation and updates, extensive view composition (with auto-layout and routing), folder management, deletion, export, and robust batch/mutation control with undo/redo capabilities.

Question 5

What are the key technical requirements to use Archi?

Accepted Answer

To use Archi, you need Archi 5.7+, Java 21+, and an MCP-compatible LLM client (e.g., Claude CLI, Cline, LM Studio). An LLM model with at least 8B+ parameters is recommended for reliable tool calling, with 70B+ ideal for complex view composition.
