RPG Maker MV Ultimate MCP
RPG Maker MV Ultimate: AI copilot to generate, edit and understand RPG Maker MV projects (MCP)
Using RPG Maker MV Ultimate MCP in Claude, Cursor, Gemini CLI, Cline, or Zed?
MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

- - Semantic screen only - the deterministic conformance probe has not run on this server
- - Confidence is reported but not yet calibrated (v1)
- - Screen reads the tool description, not the live behavior
- - advisory
- - registry description only no input schema

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-08-04).
Contracts can change after screening, with no version bump. The gate pins RPG Maker MV Ultimate MCP’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

The server starts without it; needed for real editing, or call set_project_path at runtime.
VISION_API_URLBase 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_KEYBearer token for the vision endpoint (only sent when set).
VISION_MODELVision model name to request (e.g. gpt-4o, llava). Defaults to meta/llama-3.2-90b-vision-instruct.
RPGMV_LEGACY_TOOLSSet to 1 to also advertise the 101 legacy v4 tool names (they remain callable regardless of this flag).
