UE Audio MCP

AI-powered game audio toolkit — MetaSounds graph generation & export, project scanning, and Wwise/Blueprint knowledge base via MCP for Unreal Engine 5.7.

One MCP server. UE5 Plugin, three audio engines, five custom nodes for SID chip emulation. 81 tools. 195 engine-verified MetaSounds nodes. Optimised for Unreal Engine 5.7 and Wwise 2025.

"Create a footsteps sound setup for my character -- use MetaSounds noise and filter in the patch, Blueprint trigger on anim notify"

MCP generates the MetaSounds DSP graph (noise -> filter -> AD envelope) and outputs Blueprint wiring for the animation trigger.

Setup

# 1. MCP Server (Python)
git clone https://github.com/koshimazaki/UE-AUDIO-MCP.git
cd UE-AUDIO-MCP && pip install -e ".[dev]"
ue-audio-mcp
// 2. MCP Client Config (Claude Code, Cursor, etc.)
{
  "mcpServers": {
    "ue-audio-mcp": { "command": "ue-audio-mcp", "transport": "stdio" }
  }
}
// 3. UE5 Plugin — copy to project Plugins/ folder, enable in plugin manager
ue5_plugin/UEAudioMCP/        → Editor module (TCP server, 48 commands)
ue5_plugin/SIDMetaSoundNodes/  → Runtime module (SID chip nodes)

Works without Wwise or UE5 running -- knowledge base, templates, and offline mode always available.

Requirement

Version

Unreal Engine

5.7.2+ (MetaSounds Builder API, experimental since 5.4)

Wwise

2025.1.4+ (WAAPI enabled, WebSocket on localhost:8080)

See TOOLS_AND_COMMANDS.md for full tool listing, command reference, sound designer workflows, template catalogue, and knowledge base details. Run python scripts/db_inventory.py to reconcile source catalogue, SQLite, and engine export counts.


ReSID SIDKIT Edition -- C64 SID Chip in MetaSounds

5 custom C++ MetaSounds nodes wrapping a cycle-accurate MOS 6581/8580 SID chip emulator. The same reSID core running in the SIDKIT project, now available as native MetaSounds DSP nodes.

Node

Type

Description

SID Oscillator

Audio

24-bit accumulator, 8 waveforms (saw/tri/pulse/noise + combined)

SID Envelope

Float

Non-linear exponential ADSR with authentic SID timing and delay bug

SID Filter

Audio

Route any audio through the 6581's analog filter -- VICE VCR model

SID Voice

Audio

Oscillator x Envelope convenience combo

SID Chip

Audio

Complete 3-voice SID with filter, FM cross-modulation, per-voice outputs

SIDMetaSoundNodes is a separate Runtime module -- ships in games without the MCP TCP server.
