3D Slicer

Execute Python code in 3D Slicer. Parameters: code (str): The Python code to execute. The code parameter is a string containing the Python code to be executed in 3D Slicer's Python environment. The code should be executable by Python's `exec()` function. To get return values, the code should assign the result to a variable named `__execResult`. Examples: - Create a sphere model: {"tool": "execute_python_code", "arguments": {"code": "sphere = slicer.vtkMRMLModelNode(); slicer.mrmlScene.AddNode(sphere); sphere.SetName('MySphere'); __execResult = sphere.GetID()"}} - Get the number of nodes in the current scene: {"tool": "execute_python_code", "arguments": {"code": "__execResult = len(slicer.mrmlScene.GetNodes())"}} - Calculate 1+1: {"tool": "execute_python_code", "arguments": {"code": "__execResult = 1 + 1"}} Returns: dict: A dictionary containing the execution result. If the code execution is successful, the dictionary will contain the following key-value pairs: - "success": True - "message": The result of the code execution. If the code assigns the result to `__execResult`, the value of `__execResult` is returned, otherwise it returns empty. If the code execution fails, the dictionary will contain the following key-value pairs: - "success": False - "message": A string containing an error message indicating the cause of the failure. The error message may come from the Slicer Web Server or the Python interpreter. Examples: - Successful execution: {"success": True, "message": 2} # Assuming the result of 1+1 is 2 - Successful execution: {"success": True, "message": "vtkMRMLScene1"} # Assuming the created sphere id is vtkMRMLScene1 - Python execution error: {"success": False, "message": "Server error: name 'slicer' is not defined"} - Connection error: {"success": False, "message": "Connection error: ..."} - HTTP error: {"success": False, "message": "HTTP Error 404: Not Found"}

Capture a screenshot from 3D Slicer's views. This tool provides real-time visual feedback of the current state of Slicer, enabling AI to observe the GUI and make informed decisions in a complete REACT loop. Parameters: view_type (str): Type of screenshot to capture. Options: - "application" (default): Full application window including all panels and views - "slice": A specific slice view (Red/Yellow/Green) - "3d": The 3D rendering view view_name (str): For slice views, specify which view to capture. Options: "red", "yellow", "green" Only used when view_type="slice" slice_offset (float): For slice views, offset in mm relative to slice origin. Only used when view_type="slice" slice_orientation (str): For slice views, specify orientation. Options: "axial", "sagittal", "coronal" Only used when view_type="slice" camera_axis (str): For 3D views, specify camera view direction. Options: "L" (Left), "R" (Right), "A" (Anterior), "P" (Posterior), "I" (Inferior), "S" (Superior) Only used when view_type="3d" image_size (int): Pixel size of output image (for slice and 3D views). Only used when view_type="slice" or view_type="3d" Returns: A list containing text and/or image content. The image is returned in MCP's standard format for proper display in AI clients. Examples: - Capture full application: {"tool": "capture_screenshot", "arguments": {"view_type": "application"}} - Capture Red slice view: {"tool": "capture_screenshot", "arguments": {"view_type": "slice", "view_name": "red"}} - Capture 3D view from anterior: {"tool": "capture_screenshot", "arguments": {"view_type": "3d", "camera_axis": "A"}} - Capture axial slice: {"tool": "capture_screenshot", "arguments": {"view_type": "slice", "view_name": "red", "slice_orientation": "axial"}}
