MCP-Slicer

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.
