dcc-mcp-openusd 0.2.0

OpenUSD MCP server with daemon runtime — uvx-launchable, defaults to Pixar USD bindings

dcc-mcp-openusd

OpenUSD adapter and skills for the DCC Model Context Protocol ecosystem.

dcc-mcp-openusd runs a headless OpenUSD-oriented MCP server that can create portable USD project folders, author simple stages, add references, validate stages, and package USDZ-like archives. It is designed to plug into the dcc-mcp-core gateway and skills-first workflow.

Install

pip install dcc-mcp-openusd

This release train requires dcc-mcp-core>=0.18.2.

For full OpenUSD runtime behavior, install the optional Pixar USD bindings:

pip install "dcc-mcp-openusd[openusd]"

Run

dcc-mcp-openusd --port 8765

Then connect an MCP client to:

http://127.0.0.1:8765/mcp

Bundled Skills

The first version ships three bundled skills:

Skill	Purpose
openusd-project	Create self-contained project folders and snapshots.
openusd-stage	Create stages, list prims, define xforms, and add references.
openusd-validate	Validate stage invariants and package a USDZ-style archive.

Agents should follow the normal DCC-MCP flow:

1. search_skills(query="openusd stage")
2. load_skill("openusd-stage")
3. Call a typed tool such as openusd_stage__create_stage
4. Validate with openusd_validate__validate_stage

Scope

This repository is intentionally an adapter/domain-skill package, not a new core USD engine. dcc-mcp-core remains the shared transport, gateway, validation, telemetry, and skill-loading foundation. This package owns OpenUSD-specific project semantics, stage authoring tools, validation policy, and packaging workflows.

Development

pip install -e ".[dev]"
pytest
ruff check src tests tools
python -m build

Release

The repository uses release-please. The baseline version is 0.0.0 so the first release PR will cut v0.1.0. PyPI publishing is wired through the pypi GitHub environment.
