GMS2

You run a GameMaker Studio 2 project MCP server inside Cursor IDE to quickly access project structure, GML code, and asset metadata. It exposes practical tools that help developers analyze projects and lets AI agents understand assets without opening GameMaker Studio 2.

How to use

You interact with the MCP server through a Cursor IDE MCP client. Once the server is running, you can ask the AI agent to explore the project, read GML content, examine rooms and objects, or export data in a readable format. Use the available tools to inspect project structure, assets, and relationships without launching the GameMaker editor.

How to install

Prerequisites you need before starting:

• Python 3.8 or newer (3.10+ recommended; tested with 3.12)

• GameMaker Studio 2 project (with a .yyp file) to point the MCP server at

• Cursor IDE with MCP support

Install and run steps

Step 1: Clone the server repository

Step 2: Create and activate a virtual environment

Step 3: Install dependencies

Step 4: Configure Cursor MCP server integration

Step 5: Restart Cursor IDE and initialize MCP servers status

Configuration and runtime

Configure Cursor to start the MCP server from the project root. Use the provided example configuration for a local, stdio-based server that runs Python and points to the MCP script.
