gms-mcp 0.1.9.dev2900

GameMaker CLI + MCP server toolset

GameMaker MCP Tools

This repo provides:

• gms: a Python CLI for GameMaker project operations (asset creation, maintenance, runner, etc).
• gms-mcp: an MCP server that exposes the same operations as MCP tools (Cursor is the primary example client).
• gms-mcp-init: generates shareable MCP config files for a workspace.

Install (recommended: pipx)

pipx install gms-mcp

Local Development Setup

If you are working on the gms-mcp codebase itself, follow these steps to set up a local development environment:

1. Clone and install in editable mode:

   git checkout dev
   pip install -e .
   

2. Initialize local and global MCP servers for testing: We recommend setting up two separate MCP server configurations in Cursor to test your changes:

   • Global (gms-global): For general use across all your GameMaker projects.
   • Local (gms-local): Specifically for testing your current changes to the server.

   Run these commands from the project root:

   # Global setup (names it 'gms-global' in Cursor)
   gms-mcp-init --cursor-global --server-name gms-global --mode python-module --python python --non-interactive
   
   # Local setup (names it 'gms-local' in Cursor)
   gms-mcp-init --cursor --server-name gms-local --mode python-module --python python --non-interactive
   

3. Verify in Cursor: Go to Cursor Settings > Features > MCP to see your new servers. You may need to click "Reload" or restart Cursor to see changes.

Publishing (maintainers)

Publishing is automated via GitHub Actions (PyPI Trusted Publishing) on every push to main and on tags v*. See RELEASING.md for the one-time PyPI setup and the first manual upload helper scripts.

Use with a GameMaker project (multi-project friendly)

Run this inside each GameMaker project workspace (or repo) to generate config:

gms-mcp-init --cursor

This writes .cursor/mcp.json and attempts to auto-detect the .yyp location to set GM_PROJECT_ROOT.

For a one-time setup that works across many projects, write Cursor's global config instead:

gms-mcp-init --cursor-global

Generate example configs for other MCP-capable clients:

gms-mcp-init --vscode --windsurf --antigravity

Or generate everything at once:

gms-mcp-init --all

Monorepos / multiple .yyp

If multiple .yyp projects are detected in a workspace:

• gms-mcp-init will warn and (when interactive) prompt you to pick one.
• In non-interactive environments, it defaults GM_PROJECT_ROOT to ${workspaceFolder} (safe).

Force a specific project root:

gms-mcp-init --cursor --gm-project-root path\\to\\project

Preview output without writing files:

gms-mcp-init --cursor --dry-run

CLI usage

Run from a project directory (or pass --project-root):

gms --version
gms --project-root . asset create script my_function --parent-path "folders/Scripts.yy"
