Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
RPGMAKER_PROJECT_PATHOptional | 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_URLOptional | 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_KEYOptional, secret | Bearer token for the vision endpoint (only sent when set). |
VISION_MODELOptional | Vision model name to request (e.g. gpt-4o, llava). Defaults to meta/llama-3.2-90b-vision-instruct. |
RPGMV_LEGACY_TOOLSOptional | Set to 1 to also advertise the 101 legacy v4 tool names (they remain callable regardless of this flag). |
