## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Supply Chain Security**: 98/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.

- **Schema Quality & AI Usability**: 35/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 3485 tokens (~99/item across 35 items; 34 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.

## Common questions

### What is the unreal-mcp-ue4-for-ohd server?

unreal-mcp-ue4-for-ohd is listed in the public MCP registry as io.github.RibatTRW/unreal-mcp-ue4-for-ohd. UE4.25 MCP server for Unreal Editor via Python Remote Execution (OHD mod-kit retarget). This page covers its npm package (unreal-mcp-ue4-for-ohd).

### Is the unreal-mcp-ue4-for-ohd server safe to use?

unreal-mcp-ue4-for-ohd scores 67 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the unreal-mcp-ue4-for-ohd server expose?

unreal-mcp-ue4-for-ohd exposes 34 tools: get_unreal_engine_path, get_unreal_project_path, get_unreal_version, editor_create_object, editor_update_object, and 29 more. Their descriptions and schemas cost roughly 3,481 tokens of context every time the server is loaded.

### Is the unreal-mcp-ue4-for-ohd server still maintained?

unreal-mcp-ue4-for-ohd is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the unreal-mcp-ue4-for-ohd server under?

unreal-mcp-ue4-for-ohd declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
