How do I connect Unreal MCP Server to Claude?

Run `claude mcp add chir24-unreal-mcp -- npx -y unreal-engine-mcp-server` in Claude Code, or add the same command and arguments under mcpServers in Cursor's mcp.json or Claude Desktop's claude_desktop_config.json, then restart the client. The blocks above are ready to paste.

Is Unreal MCP Server free?

The listed licence is MIT. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.

What can Unreal MCP Server do?

Unreal MCP Server documents 23 tools to the agent, including animation_physics, build_environment, control_actor. The descriptions above come from project documentation. A live handshake does not test individual tool behavior.

claude mcp add --transport stdio 'chir24-unreal-mcp' -- 'npx' '-y' 'unreal-engine-mcp-server'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.
