🎉 Flopperam has been acquired by Aura!

  Flopperam is now part of Aura. For the latest updates to the MCP and what we're building next, head over to tryaura.dev.

Flopperam — Unreal Engine MCP

  The most advanced MCP server for Unreal Engine.
  Control a live Unreal Editor through natural language from any MCP client.

Two Ways to Use Unreal Engine MCP

This repo contains two separate things:

| | Hosted Flop MCP (Recommended) | Open-Source Local MCP (This Repo) |
| What | Production MCP server hosted at agent.flopperam.com/mcp | Community MCP server you run locally from the Python/ folder |
| Tools | 50+ tools across 9 domains — Blueprint authoring, materials, VFX, animation, landscape, AI/BT, cinematics, PCG, and more | Basic toolset — scene manipulation, actor management, world building, and foundational Blueprint operations |
| Blueprint support | Full lifecycle — batched narrow tools (bp_create, bp_variable, bp_component, bp_nodes, bp_wire, bp_commit), Graph authoring, contract verification, PIE runtime testing | Foundational — add_node, connect_nodes, create_variable, create_function with 23+ node types |
| Unreal plugin | FlopAI plugin — installed separately via flopperam.com/unreal-agent | UnrealMCP plugin — bundled in this repo under UnrealMCP/ |
| Server instructions | Rich per-tool LLM guidance, cross-tool relationship mapping, error recovery patterns | Basic tool descriptions |
| Setup | One URL + API key, no local dependencies | Clone repo, Python 3.12+, run server locally |
| Works with | Cursor, Claude Code, Windsurf, VS Code Copilot, Cline, any MCP client | Same |

> The hosted Flop MCP is a completely different, much more advanced server that shares no code with the local Python/ server in this repo. It is actively developed with new tools shipping regularly.

Hosted Flop MCP (Recommended)

One URL, one API key. No local server, no Python install. Works with Cursor, Claude Code, Windsurf, VS Code Copilot, Cline, and any other MCP client.

1. Get an API key at flopperam.com/account

2. Install the FlopAI Unreal plugin — see flopperam.com/docs (Installation tab)

3. Add the config to your IDE

Cursor — .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):
json
{
  "mcpServers": {
    "flopperam-unreal": {
      "url": "https://agent.flopperam.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Claude Code — run in your terminal:
bash
claude mcp add -H "Authorization: Bearer YOUR_API_KEY" --transport http flopperam-unreal https://agent.flopperam.com/mcp

VS Code / Copilot — .vscode/mcp.json:
json
{
  "servers": {
    "flopperam-unreal": {
      "type": "http",
      "url": "https://agent.flopperam.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cline / Local LLMs (Ollama, LM Studio, etc.):
json
{
  "mcpServers": {
    "flopperam-unreal": {
      "type": "streamableHttp",
      "url": "https://agent.flopperam.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Verify the server shows as connected in your IDE and start prompting.
