Runtime Schema & MCP Contract

Supercharge your AI in the real world.

The standard contract any AI assistant uses to drive the RakuAI runtime — 17 native MCP tools, adapter manifests, scene-state snapshots. 9,500+ REST endpoints. 10,328 bound engine functions.

For AI Assistants & Agents

17 Native MCP Tools

The MCP server exposes a fixed surface — get_scene_state, add_scene_node, load_world_model, … (5 read-only + 12 mutation; see mcp.html). Read-only tools work in every mode; mutating tools are sandbox/dev only.

Standard Contract, Any Agent

Drive the runtime from Claude Desktop, Cursor, custom GPTs, or any MCP-capable client. The tool surface is the same. Wiring guides for Claude Desktop are live now; more clients are in flight.

API Reference

Full server, adapter, and scene-state schemas are available under NDA. Request NDA access for the complete integration kit.

The MCP Surface

Every external agent reaches the engine through the same 17 native tools. Deny-by-default permissions, typed schemas, full audit log. The server is the boundary — the engine remains the authority on physics, collision, scoring, and multiplayer state.

Engine Subsystems

The Raku engine is modular with subsystems covering rendering, physics, audio, AI, XR, networking, animation, and more. Adapters plug in over the MCP boundary; the engine retains deterministic authority.
