unreal-metasound SKILL.md skillA
unreal-metasound from dcc-mcp/dcc-mcp-unreal is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dcc-mcp/dcc-mcp-unreal/unreal-metasound@git:20260726.7b7839fPins git:20260726.7b7839f in mdr.lock. Pin the fingerprint instead.

Unreal Engine MetaSound Source authoring through the reflected Builder API: create sources, add typed inputs and exact registered nodes, connect opaque vertex handles, set defaults, inspect nodes, build, save, and validate. Use for procedural audio graphs in Unreal Engine 5.4+. Not for arbitrary asset management or Blueprint gameplay logic.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Unreal MetaSound Tools
Author MetaSound Source assets through Unreal's public reflected APIs:
`MetaSoundBuilderSubsystem`, `MetaSoundEditorSubsystem`, and
`EditorValidatorSubsystem`.
## Workflow
1. Call `unreal_metasound__create_metasound_source`. Keep the returned initial
output/input handle tokens.
2. Add graph inputs or nodes. Nodes require an exact registry identity
(`namespace`, `class_name`, `variant`, `major_version`); this skill never
maps a broad label such as "Filter" to an arbitrary class.
3. Use the exact vertex handles returned by create/add/inspect with
`unreal_metasound__connect_metasound_nodes`.
4. Set supported graph-input defaults, then build and validate.
For example, Unreal 5.8 registers a sine oscillator as:
```json
{
"namespace": "UE",
"class_name": "Sine",
"variant": "Audio",
"major_version": 1
}
```
## Handle contract
Node and pin handles are opaque Unreal Builder tokens:
```text
(NodeID=0123456789ABCDEF0123456789ABCDEF)
(NodeID=0123456789ABCDEF0123456789ABCDEF,VertexID=FEDCBA9876543210FEDCBA9876543210)
```
Do not edit or synthesize them. A mutating call verifies that each handle
belongs to the target graph before changing it.

How to install
mdr add dcc-mcp/dcc-mcp-unreal/unreal-metasound@sha256:f5f513340fd78a17The line at the top of this page pins the label git:20260726.7b7839f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
