What is Gaphor MCP Server?

The Gaphor MCP Server is a bridge between your Gaphor modeling tool and other applications. It implements the Model Context Protocol (MCP) standard, allowing you to query, modify, and visualize your models through a standardized interface.

How to use Gaphor MCP Server?

You can connect to the server from any MCP-compatible client (like VSCode extensions) to interact with your Gaphor models. The server supports querying model elements, modifying the model structure, and generating various types of diagrams.

Use Cases

Ideal for developers who want to integrate their code with UML models, validate models against actual implementations, ensure proper documentation, and maintain consistency between design and code.

Key Features

Model QueryingSearch and retrieve elements from your Gaphor models using various filters and criteria

Model ModificationAdd, update or remove elements in your models programmatically

Diagram GenerationCreate different types of diagrams (class diagrams, sequence diagrams, etc.) from your models

Code IntegrationConnect your models with actual code implementations for validation and documentation

Pros and Cons

Frequently Asked Questions

What is Model Context Protocol (MCP)?MCP is a standard protocol for interacting with models, similar to how LSP (Language Server Protocol) works for code editors.

Do I need to know MCP to use this server?No, you can use client tools that implement MCP (like VSCode extensions) without knowing the protocol details.

Can I use this with other modeling tools besides Gaphor?Currently this implementation is specific to Gaphor, but the MCP standard is tool-agnostic.

Is there a graphical interface for the server?The server itself runs in the background. You interact with it through client applications or programming.
