chops

chops

MCP tool wrappers for Houdini CHOP (Channel Operator) operations.

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

Functions:

Name	Description
create_chop_node	Create a new CHOP node.
export_chop_to_parm	Export a CHOP channel to a parameter via a chop() expression.
get_chop_data	Get CHOP node track data.
list_chop_channels	List all channels on a CHOP node.

Functions

create_chop_node async

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

Create a new CHOP node.

Before using this, call list_node_types(context='Chop', filter='') to verify the correct node type. CHOPs has many dedicated nodes for motion and timing — noise, wave, spring, jiggle, lag, limit, filter, math, function, blend, shift, stretch, trim, cycle, speed, constraintlookatat, constraintpath — that may already do what you need.

Parameters:

Name	Type	Description	Default
parent_path	str	Parent network path.	required
chop_type	str	CHOP node type to create.	required
name	Optional[str]	Node name override.	None

export_chop_to_parm async

export_chop_to_parm(
    ctx: Context,
    chop_path: str,
    channel_name: str,
    target_node_path: str,
    target_parm_name: str,
) -> dict

Export a CHOP channel to a parameter via a chop() expression.

Parameters:

Name	Type	Description	Default

target_parm_name	str	Parameter to receive the export.	required

get_chop_data async

get_chop_data(
    ctx: Context,
    node_path: str,
    channel_name: Optional[str] = None,
    start: Optional[int] = None,
    end: Optional[int] = None,
) -> dict

Get CHOP node track data.

Parameters:

Name	Type	Description	Default
node_path	str	CHOP node path.	required
channel_name	Optional[str]	Specific channel to retrieve.	None
start	Optional[int]	Start sample index.	None
end	Optional[int]	End sample index.	None

list_chop_channels async

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