// Overview of the Flopperam Unreal Engine MCP server -- tool categories, workflows, and cross-tool relationships. Use when first connecting to a running Unreal Editor, when unsure which tool handles a task, or when the user asks about available capabilities.
Blueprint authoring workflow for the Flopperam Unreal Engine MCP. Covers the full create, author, commit, verify cycle using the narrow bp_* tool surface. Use when creating or editing Blueprints, adding variables/components/events/functions, wiring graphs, or debugging compile errors.
Material authoring and VFX workflow for the Flopperam Unreal Engine MCP. Covers material creation, expression graphs, Niagara particle systems, Chaos destruction, and curve assets. Use when creating materials, material instances, Niagara systems, destruction effects, or procedural audio.
Scene and world building workflow for the Flopperam Unreal Engine MCP. Covers actor management, landscape sculpting, foliage scattering, AI setup, cinematics, and level verification. Use when placing actors, building environments, working with landscapes/foliage, setting up AI characters, or creating Level Sequences.

This MCP server controls a live Unreal Editor instance over WebSocket. Every tool operates on the running editor — if a tool returns a connection error, the editor may not be running or the FlopAI plugin is not loaded.
Before calling any tool, classify what the user needs:
When intent is unclear, default to answering rather than modifying.
