Houdini MCP
Drive SideFX Houdini nodes and procedural FX from your agent.
What it does
Two credible community servers cover Houdini. capoomgit/houdini-mcp is the original: a Python plugin plus bridge script that creates and wires nodes and executes code over a localhost socket. healkeiser/fxhoudinimcp is the larger and more actively developed one — 179 tools across SOPs, LOPs/USD, DOPs, PDG/TOPs, COPs, HDAs, animation, rendering and VEX, with a one-command installer. Either opens Houdini's procedural FX and sim toolset to agent-driven work; neither is from SideFX.
Connect
Local install: pip install fxhoudinimcp && python -m fxhoudinimcp install (registers both the Houdini package and the client entry). capoomgit/houdini-mcp is manual: copy its plugin into the Houdini scripts dir.
Field notes
healkeiser/fxhoudinimcp: 168 stars, MIT, PyPI 2.10.0, pushed Jul 29 2026 — fewer stars than the original but far broader coverage and the better-maintained of the two; it is the one to try first. capoomgit/houdini-mcp: 279 stars, MIT, last push Jun 11 2026, still early-stage and manual to install. SideFX itself has no shipping MCP: the H22 'APEX Script comfort package' (AI-assisted rigging-code authoring, autocomplete, validation) was shown at the Houdini 22 keynote in June 2026 and SideFX's own page calls it 'a preview for a tool which will be released later on' — trade coverage describes an APEX Script MCP server headed to SideFX Labs, but SideFX has not documented one. Do not plan a pipeline around it yet. For Cinema 4D, the leading equivalent is ttiimmaacc/cinema4d-mcp (110 stars, last push Mar 2026, C4D 2024+, MoGraph/Redshift tools).
