Houdini MCP

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 — 188 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: 318 stars, MIT, PyPI 2.25.0 (5 Oct 2026, repo pushed the same day), tested through Houdini 22.0.368 — 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: 285 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 and SideFX's own page calls it 'a preview for a tool which will be released later on' — trade coverage from SIGGRAPH 2026 describes an APEX Script MCP server headed to SideFX Labs, but as of Sep 2026 SideFX has not documented one and it is not in the core product. Do not plan a pipeline around it yet. For Cinema 4D, Maxon now ships an official server inside C4D 2026.4 (see cinema4d); on older versions the community ttiimmaacc/cinema4d-mcp (129 stars, last push Mar 2026, C4D 2024+, MoGraph/Redshift tools) is the equivalent.
