What the code does

We read the source, 23 h ago · rules 3dff92dd89df

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    const content = await readFile(path.join(dir, file), "utf-8");

  const child = spawn(gameExe, args, { cwd: projectPath, detached: true, stdio: 'ignore', windowsHide: false });

      const files = await readdir(fullDir);

This one needs environment variables set before it will start: RPGMAKER_PROJECT_PATH (Absolute path to the RPG Maker MV project to edit (the folder with data/ and js/). The server starts without it; needed for real editing, or call set_project_path at runtime.), VISION_API_URL (Base URL of an OpenAI-compatible vision endpoint to enable analyze_image mode "ai" (e.g. https://api.openai.com or http://localhost:11434). Unset = vision disabled; every other tool works offline.), VISION_API_KEY (Bearer token for the vision endpoint (only sent when set).), VISION_MODEL (Vision model name to request (e.g. gpt-4o, llava). Defaults to meta/llama-3.2-90b-vision-instruct.), RPGMV_LEGACY_TOOLS (Set to 1 to also advertise the 101 legacy v4 tool names (they remain callable regardless of this flag).). The author declared them in the registry entry; get the values from the project itself.
