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
secret
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).
