The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

claude mcp add ribattrw-unreal-mcp-ue4-for-ohd -- npx -y unreal-mcp-ue4-for-ohd
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 66 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 November 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 5 November 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.
What did VerifyMCP test on the unreal-mcp-ue4-for-ohd server?
VerifyMCP ran 16 checks on unreal-mcp-ue4-for-ohd, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
