Houdini Node Help
Use when writing or editing help documentation for a Houdini node or digital asset — the node help card, the Help tab of Type Properties, or a .txt file under help/nodes/. Also use when help text renders wrong, a parameter's help does not appear beside its parameter, or a help file is not picked up by the help server.
Houdini Locator
Locates Houdini installations across Windows and Linux. Honors the HFS environment variable as highest priority when it points at a real install; otherwise scans standard Side Effects Software directories on Windows and /opt/hfs* paths on Linux. Use this when you need to find where Houdini is installed, which versions are available, or the path to hython/houdinifx.
Houdini Env
Houdini environment variables and package configuration. Use when the user needs to set up, debug, or understand Houdini environment variables, houdini.env files, or JSON package plugins.
Houdini Lite
Inspect Houdini bgeo.sc geometry caches, OpenVDB volume caches, and USD scene files using MCP tools, without loading full geometry into memory. Use when the user needs to read cache metadata, VDB grid lists, attribute info, frame sequences, USD hierarchy, composition arcs, cameras, replace anchors, add / insert / remove sublayers, or stitch USD value clips.
Houdini Cli
Interact with Houdini command-line tools (ginfo, gconvert, hrender, hython, etc.). Use when user needs to analyze geometry, convert files, render scenes, or run Houdini Python scripts.
Houdini Docs Local
Use when looking up Houdini documentation — a HOM method signature, a VEX function, an expression function, an hscript command, a node's parameters — and especially when sidefx.com is unreachable, blocked by a studio network, or slow. Also use when the answer must match the installed Houdini version rather than the current release.
Houdini Tools
Lightweight Houdini toolkit: CLI skills + MCP server for inspecting .bgeo.sc caches and USD scenes — no Houdini installation required. Plugin for Claude Code, Codex, and Gemini CLI.
