maya-expressions SKILL.md skillA
maya-expressions from dcc-mcp/dcc-mcp-maya is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dcc-mcp/dcc-mcp-maya/maya-expressions@git:20261101.26ecf7ePins git:20261101.26ecf7e in mdr.lock. Pin the fingerprint instead.

Authoring stage Maya expression nodes: create, list, delete procedural expressions that drive attributes. Use for procedural animation / rig logic. Not for keyframe animation (maya-animation) or arbitrary scripting (maya-scripting).
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
# maya-expressions (Authoring stage) Lifecycle for Maya expression nodes (`expression` DG nodes). Four small scripts � kept as a dedicated skill rather than folded into `maya-scripting` because they have a stable schema and benefit from typed parameters. ## Scripts - `create_expression` � Create a Maya expression node - `list_expressions` � List Maya expression nodes in the scene - `delete_expression` � Delete a Maya expression node by name - `get_expression_string` � Read the MEL expression body of a node ## Restricted mode `create_expression` and `edit_expression` are **code-bearing**: the expression string is evaluated by Maya and a MEL expression can embed `python(...)`. When `DCC_MCP_MAYA_DISABLE_ARBITRARY_SCRIPT=1` is set before Maya starts, both tools return a structured operator-policy refusal before touching the host. This is an adapter-local tool policy, not a sandbox: read-only tools (`list_expressions`, `delete_expression`) remain available, and code already present in the session is out of scope. See `dcc_mcp_maya._code_policy` for the canonical inventory.

How to install
mdr add dcc-mcp/dcc-mcp-maya/maya-expressions@sha256:287fc73db22691d0The line at the top of this page pins the label git:20261101.26ecf7e, 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.
