cops

cops

MCP tool wrappers for Houdini COP (Copernicus) operations.

Each tool delegates to the corresponding handler running inside Houdini via the HTTP bridge.

Functions:

Name	Description
create_cop_node	Create a COP node in the specified network.
get_cop_geometry	Get geometry representation from a COP node.
get_cop_info	Get information about a COP node.
get_cop_layer	Get image layer data from a COP node.
get_cop_vdb	Get VDB volumetric data from a COP node.
list_cop_node_types	List available COP node types.
set_cop_flags	Set flags on a COP node.

Functions

create_cop_node async

create_cop_node(
    ctx: Context, parent_path: str, cop_type: str, name: Optional[str] = None
) -> dict

Create a COP node in the specified network.

Before using this, call list_node_types(context='Cop', filter='') for Copernicus nodes (Houdini 20+), or context='Cop2' for legacy COPs. Copernicus is the modern image processing system and is preferred over COP2 (deprecated as of Houdini 20.5). COPs has many dedicated image-processing nodes — blur, sharpen, levels, contrast, over, multiply, luminance, premultiply, channelcopy, noise, ramp, fractalnoise, worleynoise, rasterizegeo, heighttonormal, sdfshape — that may cover the operation without needing a VEX COP or Python.

Parameters:

Name	Type	Description	Default
parent_path	str	Path to the parent COP network.	required
cop_type	str	COP node type to create.	required
name	Optional[str]	Override node name.	None

get_cop_geometry async

get_cop_geometry(ctx: Context, node_path: str, output_index: int = 0) -> dict

Get geometry representation from a COP node.

Parameters:

Name	Type	Description	Default
node_path	str	Path to the COP node.	required
output_index	int	Output connector index.	0

get_cop_info async

get_cop_info(ctx: Context, node_path: str) -> dict

Get information about a COP node.

Parameters:

Name	Type	Description	Default
node_path	str	Path to the COP node.	required

get_cop_layer async

get_cop_layer(ctx: Context, node_path: str, output_index: int = 0) -> dict

Get image layer data from a COP node.

Parameters:

Name	Type	Description	Default
node_path	str	Path to the COP node.	required
output_index	int	Output connector index.	0

get_cop_vdb async

get_cop_vdb(ctx: Context, node_path: str, output_index: int = 0) -> dict

output_index	int	Output connector index.	0

list_cop_node_types async

list_cop_node_types(ctx: Context, filter: Optional[str] = None) -> dict

List available COP node types.

Parameters:

Name	Type	Description	Default
filter	Optional[str]	Substring filter for node type names.	None

set_cop_flags async

set_cop_flags(
    ctx: Context,
    node_path: str,
    display: Optional[bool] = None,
    export_flag: Optional[bool] = None,
    compress: Optional[bool] = None,
) -> dict

Set flags on a COP node.

Parameters:

Name	Type	Description	Default
node_path	str	Path to the COP node.	required
display	Optional[bool]	Display flag state.	None
export_flag	Optional[bool]	Render/export flag state.	None
compress	Optional[bool]	Compress flag state.	None
