RPG Maker MV Ultimate MCP

2. Sign in if asked the first time Claude connects.
3. Check it: run /mcp in Claude Code and look for it in the list.

What it needs

• 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: keep it out of your repo. 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).

Environment variables as listed in the server's MCP Registry entry.
