Pipeline skill — viewport capture/flipbook plus ROP render settings and render execution through typed, runtime-aware tools. Exports report written_files, elapsed time, and separate error/warning diagnostics without hanging the host. Pair with houdini-camera-light to set up cameras and lights first.
Scene skill — read-only inspection of the active Houdini hip file and node graphs. Use when you need frame range, hip path, object-level nodes, or node details. Not for creating geometry, sims, or exports — use authoring or interchange skills.
Authoring skill — inspect and edit Houdini node parameters, parameter templates, spare parameters, and channel expressions through typed atomic tools. Use instead of arbitrary Python for reading/setting parms, adding spare parms, and managing expressions. For node connections use houdini-node-graph.
Pipeline skill — generic, adapter-owned project and shot/package automation: set/query the project root, tag and read portable asset metadata, validate a scene for missing files / bad output dirs / dirty state / cook errors, collect file dependencies into a manifest (no copying), and export a shot/package manifest (frame range, cameras, output nodes, caches, written files). No dependency on private production services.
Scene-management skill — typed Houdini scene lifecycle (new/open/save with dirty-scene safeguards), selection (get/set/find), camera discovery, and bounding-box queries. Use these atomic tools instead of arbitrary Python for everyday scene navigation and file operations. Not for node authoring (use houdini-nodes) or geometry/transform edits (use houdini-object-ops).
Set up dcc-mcp-houdini for an agent or operator: install Houdini Python dependencies with hython, generate MCP host configuration, guide the user through the Houdini package / 123.py autostart load step, and run a first live-tool smoke prompt.

Typed CHOP tools for agents. All tools are affinity: main.
network: create_chop_network — create and manage CHOP container networks.motion: create_motionclip — import or create motion clip CHOPs for
animation data.audio: create_audio_driven — set up audio-driven animation channels
using Audio/Envelope CHOPs.filter: apply_filter — apply procedural CHOP filters (lag, spring,
noise, smooth).export: export_to_keyframes — bake CHOP channel data to object
keyframes.inspect: get_channel_info — inspect CHOP node channels (names, sample
rate, length, value range).create_chop_network(network_path="/ch/motion_fx")create_motionclip(network_path="/ch/motion_fx", node_name="walk_cycle", clip_file="/tmp/walk.bclip")apply_filter(network_path="/ch/motion_fx", source_node="walk_cycle", filter_type="lag", amount=0.5)get_channel_info(node_path="/ch/motion_fx/lag1")export_to_keyframes(node_path="/ch/motion_fx/lag1", target_path="/obj/geo1", parm_names=["tx", "ty"])create_audio_driven can point at a .wav file or use an existing audio node.
The envelope follower produces amplitude-driven channels that can be wired to
any object parameter.
