dcc-mcp-maya-setup

dcc-mcp-maya setup

Use this skill when a user wants an agent to prepare a machine so any MCP host can use dcc-mcp-maya with Autodesk Maya.

This is an operator skill, not a Maya runtime skill. Do not load it through the Maya MCP server. Run it from the repository checkout or copy its steps into another agent's instructions.

If the user says "帮我参考 dcc-mcp/dcc-mcp-maya/install.md 去安装", read the root install.md first, then follow this skill.

Goal

End with:

• dcc-mcp-maya and its pip dependencies installed into the target Maya mayapy environment.
• An MCP host config snippet that points to the Maya plugin gateway.
• The user guided to load dcc_mcp_maya_plugin.py in Maya's Plug-in Manager.
• A live smoke prompt that proves the agent can discover and call Maya tools.

Fast Path

From the repository root, run:

python skills/dcc-mcp-maya-setup/scripts/setup_dcc_mcp_maya.py

The script:

1. Finds mayapy from --mayapy, MAYAPY, DCC_MCP_MAYA_MAYAPY, PATH, or common Autodesk install locations.
2. Installs this checkout into Maya with the sidecar extra: mayapy -m pip install -e ".[sidecar]".
3. Verifies adapter imports and requires the installed Core version to satisfy dcc-mcp-core>=0.19.45,<1.0.0.
4. Writes reusable MCP JSON snippets under .dcc-mcp/agent-setup/.

Use PyPI instead of the local checkout when setting up an end-user machine:

python skills/dcc-mcp-maya-setup/scripts/setup_dcc_mcp_maya.py --source pypi

If discovery fails, ask the user for the full mayapy path and re-run:

python skills/dcc-mcp-maya-setup/scripts/setup_dcc_mcp_maya.py --mayapy "C:\Program Files\Autodesk\Maya2025\bin\mayapy.exe"

MCP Configuration

Plugin sidecar mode is the preferred default. Configure the MCP host with:

{
  "mcpServers": {
    "maya": {
      "url": "http://127.0.0.1:9765/mcp"
    }
  }
}

For an explicit direct connection, run dcc-mcp-cli list and use the exact instance URL published there; do not hardcode an instance port.

When editing an existing MCP config, preserve unrelated servers. Merge only the maya server entry unless the user asks for a different server name.

User Hand-Off: Load the Maya Plugin

After pip setup and MCP JSON generation, tell the user:

1. Open Autodesk Maya.
2. Go to Window > Settings/Preferences > Plug-in Manager.
3. Add or find dcc_mcp_maya_plugin.py.
4. Check Loaded; optionally check Auto load.
5. Watch Script Editor output for the MCP URL.

Expected plugin-mode URL is usually http://127.0.0.1:9765/mcp.

If the plugin is not visible, verify that maya/plugin/dcc_mcp_maya_plugin.py is on MAYA_PLUG_IN_PATH or copy it into the user's Maya plug-ins folder.

First Live Smoke Prompt

Ask the MCP host to run this prompt after Maya is open and the plugin is loaded:

Use the Maya MCP server. First call dcc_capability_manifest with loaded_only=false.
Then load the maya-primitives skill, create a sphere named mcp_setup_smoke_sphere
with radius 2, list scene objects, and tell me the MCP URL and created object name.
Use typed tools where available and avoid execute_python unless no typed tool fits.

Expected behavior:

• The agent discovers capabilities without dumping every schema.
• The agent loads maya-primitives.
• The agent calls maya_primitives__create_sphere.
• The new object appears in the Maya scene.
• maya_scene__list_objects or another scene query confirms it exists.

Troubleshooting

• mayapy not found: ask for the exact Maya version and mayapy path.
• Pip bootstrap fails: run mayapy -m ensurepip --upgrade, then repeat install.
• MCP connection refused: Maya is not running, the plugin is not loaded, or the host cached a stale direct URL; use gateway 9765 or refresh with dcc-mcp-cli list.
• Tool missing: call dcc_capability_manifest or search_skills, then load_skill("<skill-name>").
• Plugin loaded but hangs: check Script Editor output, firewall/localhost rules, and whether a blocking Maya dialog is open.
