list_nodes
List MRML nodes via the Slicer Web Server API.
The filter_type parameter specifies the type of node information to retrieve.
Possible values include "names" (node names), "ids" (node IDs), and "properties" (node properties).
The default value is "names".
The class_name, name, and id parameters are optional and can be used to further filter nodes.
The class_name parameter allows filtering nodes by class name.
The name parameter allows filtering nodes by name.
The id parameter allows filtering nodes by ID.
Examples:
- List the names of all nodes: {"tool": "list_nodes", "arguments": {"filter_type": "names"}}
- List the IDs of nodes of a specific class: {"tool": "list_nodes", "arguments": {"filter_type": "ids", "class_name": "vtkMRMLModelNode"}}
- List the properties of nodes with a specific name: {"tool": "list_nodes", "arguments": {"filter_type": "properties", "name": "MyModel"}}
- List nodes with a specific ID: {"tool": "list_nodes", "arguments": {"filter_type": "ids", "id": "vtkMRMLModelNode123"}}
Returns a dictionary containing node information.
If filter_type is "names" or "ids", the returned dictionary contains a "nodes" key, whose value is a list containing node names or IDs.
Example: {"nodes": ["node1", "node2", ...]} or {"nodes": ["id1", "id2", ...]}
If filter_type is "properties", the returned dictionary contains a "nodes" key, whose value is a dictionary containing node properties.
Example: {"nodes": {"node1": {"property1": "value1", "property2": "value2"}, ...}}
If an error occurs, a dictionary containing an "error" key is returned, whose value is a string describing the error.
