Unreal Engine context, in any IDE
One URL, one API key. If your AI tool supports MCP, it can inspect, search, and build inside your running Unreal Editor — right now.
Standard HTTP endpoint
Plain HTTP + JSON-RPC — the official MCP transport. No SDKs, no plugins on the client side.
Works on any device
Desktop IDEs, cloud workspaces, CI pipelines — if it can POST to a URL, it connects.
Any LLM, any provider
Claude, GPT, Gemini, Llama, Qwen, Mistral — your model, your client, your choice.
The Flop Agent
The full Unreal Engine AI
Lives inside Unreal Engine. Plans multi-step workflows, writes and executes code, recovers from errors, and iterates until the job is done. It doesn't just call tools — it reasons about your scene, your Blueprints, and your intent.
Decomposes complex requests into steps and adapts when something goes wrong.
Tuned prompts, specialized routing, deep knowledge of UE APIs and Blueprints.
Detects failures, reads error output, retries with corrections.
Maintains scene state, remembers prior actions across long conversations.
Executes commands directly inside the Unreal Editor — spawning actors, editing Blueprints, building levels.
Routes to the best model per task — Opus for reasoning, Flash for lookups.
Flop MCP
Unreal data in your IDE
Exposes your Unreal project as tools that any MCP-compatible IDE can call. Your IDE's AI does the reasoning — the MCP provides the data. Great for quick lookups, project exploration, and keeping Unreal context in your coding workflow.
Works in any MCP client
Cursor, Claude Code, Windsurf, Cline, or local LLMs via Ollama.
Uses your IDE's AI
No Flop Agent credits consumed — billed through your IDE subscription.
Free tier available
11 read-only tools permanently — inspect scenes, assets, Blueprints, and more.
Keep in mind: The Flop MCP provides data through fixed tool interfaces. It can't plan workflows, recover from errors, or adapt its approach. For complex Unreal work, the Flop Agent is purpose-built for that.
