Houdini MCP Integration

Example Use Cases

• 1

  Programmatically create, modify, and delete 3D objects and materials inside Houdini via MCP.

• 2

  Run arbitrary Python code inside Houdini and trigger renders from an external AI assistant.

• 3

  Inspect and query detailed scene and object information to inform automated modeling or scene-management tasks.

Description

HoudiniMCP implements a socket-based MCP server that lets an external agent (Claude) interact directly with a running Houdini instance. It provides two-way communication for creating, modifying, and deleting objects, applying materials, querying scene and object details, executing arbitrary Python code in Houdini, and triggering renders. The Houdini extension runs a background socket thread while executing commands on Houdini's main thread for thread-safety. This is a third-party, experimental integration—use caution with execute_houdini_code and always save your work before running complex operations.
